Name
 
  cmake - Cross-Platform Makefile Generator.
 
------------------------------------------------------------------------------
Usage
 
  cmake [options] <path-to-source>
  cmake [options] <path-to-existing-build>
 
------------------------------------------------------------------------------
Description
 
The "cmake" executable is the CMake command-line interface.  It may be used
to configure projects in scripts.  Project configuration settings may be
specified on the command line with the -D option.  The -i option will cause
cmake to interactively prompt for such settings.
 
CMake is a cross-platform build system generator.  Projects specify their
build process with platform-independent CMake listfiles included in each
directory of a source tree with the name CMakeLists.txt.  Users build a
project by using CMake to generate a build system for a native tool on their
platform.
 
------------------------------------------------------------------------------
Options
 
  -C <initial-cache>
      Pre-load a script to populate the cache.
 
      When cmake is first run in an empty build tree, it creates a
      CMakeCache.txt file and populates it with customizable settings for
      the project.  This option may be used to specify a file from which to
      load cache entries before the first pass through the project's cmake
      listfiles.  The loaded entries take priority over the project's
      default values.  The given file should be a CMake script containing
      SET commands that use the CACHE option, not a cache-format file.
 
  -D <var>:<type>=<value>
      Create a cmake cache entry.
 
      When cmake is first run in an empty build tree, it creates a
      CMakeCache.txt file and populates it with customizable settings for
      the project.  This option may be used to specify a setting that takes
      priority over the project's default value.  The option may be repeated
      for as many cache entries as desired.
 
  -U <globbing_expr>
      Remove matching entries from CMake cache.
 
      This option may be used to remove one or more variables from the
      CMakeCache.txt file, globbing expressions using * and ? are supported.
      The option may be repeated for as many cache entries as desired.
 
      Use with care, you can make your CMakeCache.txt non-working.
 
  -G <generator-name>
      Specify a makefile generator.
 
      CMake may support multiple native build systems on certain platforms.
      A makefile generator is responsible for generating a particular build
      system.  Possible generator names are specified in the Generators
      section.
 
  -Wno-dev
      Suppress developer warnings.
 
      Suppress warnings that are meant for the author of the CMakeLists.txt
      files.
 
  -Wdev
      Enable developer warnings.
 
      Enable warnings that are meant for the author of the CMakeLists.txt
      files.
 
  -E
      CMake command mode.
 
      For true platform independence, CMake provides a list of commands that
      can be used on all systems.  Run with -E help for the usage
      information.  Commands available are: chdir, compare_files, copy,
      copy_directory, copy_if_different, echo, echo_append, environment,
      make_directory, md5sum, remove, remove_directory, rename, tar, time,
      touch, touch_nocreate.  In addition, some platform specific commands
      are available.  On Windows: comspec, delete_regv, write_regv.  On
      UNIX: create_symlink.
 
  -i
      Run in wizard mode.
 
      Wizard mode runs cmake interactively without a GUI.  The user is
      prompted to answer questions about the project configuration.  The
      answers are used to set cmake cache values.
 
  -L[A][H]
      List non-advanced cached variables.
 
      List cache variables will run CMake and list all the variables from
      the CMake cache that are not marked as INTERNAL or ADVANCED.  This
      will effectively display current CMake settings, which can be then
      changed with -D option.  Changing some of the variable may result in
      more variables being created.  If A is specified, then it will display
      also advanced variables.  If H is specified, it will also display help
      for each variable.
 
  --build <dir>
      Build a CMake-generated project binary tree.
 
      This abstracts a native build tool's command-line interface with the
      following options:
 
        <dir>          = Project binary directory to be built.
        --target <tgt> = Build <tgt> instead of default targets.
        --config <cfg> = For multi-configuration tools, choose <cfg>.
        --clean-first  = Build target 'clean' first, then build.
                          (To clean only, use --target 'clean'.)
        --use-stderr  =  Don't merge stdout/stderr.
        --            = Pass remaining options to the native tool.
 
      Run cmake --build with no options for quick help.
 
  -N
      View mode only.
 
      Only load the cache.  Do not actually run configure and generate
      steps.
 
  -P <file>
      Process script mode.
 
      Process the given cmake file as a script written in the CMake
      language.  No configure or generate step is performed and the cache is
      not modified.  If variables are defined using -D, this must be done
      before the -P argument.
 
  --find-package
      Run in pkg-config like mode.
 
      Search a package using find_package() and print the resulting flags to
      stdout.  This can be used to use cmake instead of pkg-config to find
      installed libraries in plain Makefile-based projects or in
      autoconf-based projects (via share/aclocal/cmake.m4).
 
  --graphviz=[file]
      Generate graphviz of dependencies.
 
      Generate a graphviz input file that will contain all the library and
      executable dependencies in the project.
 
  --system-information [file]
      Dump information about this system.
 
      Dump a wide range of information about the current system.  If run
      from the top of a binary tree for a CMake project it will dump
      additional information such as the cache, log files etc.
 
  --debug-trycompile
      Do not delete the try_compile build tree.  Only useful on one
      try_compile at a time.
 
      Do not delete the files and directories created for try_compile calls.
      This is useful in debugging failed try_compiles.  It may however
      change the results of the try-compiles as old junk from a previous
      try-compile may cause a different test to either pass or fail
      incorrectly.  This option is best used for one try-compile at a time,
      and only when debugging.
 
  --debug-output
      Put cmake in a debug mode.
 
      Print extra stuff during the cmake run like stack traces with
      message(send_error ) calls.
 
  --trace
      Put cmake in trace mode.
 
      Print a trace of all calls made and from where with message(send_error
      ) calls.
 
  --warn-uninitialized
      Warn about uninitialized values.
 
      Print a warning when an uninitialized variable is used.
 
  --warn-unused-vars
      Warn about unused variables.
 
      Find variables that are declared or set, but not used.
 
  --no-warn-unused-cli
      Don't warn about command line options.
 
      Don't find variables that are declared on the command line, but not
      used.
 
  --check-system-vars
      Find problems with variable usage in system files.
 
      Normally, unused and uninitialized variables are searched for only in
      CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR.  This flag tells CMake to warn
      about other files as well.

Generators
 
The following generators are available on this platform:
 
  Ninja
      Generates build.ninja files (experimental).
 
      A build.ninja file is generated into the build tree.  Recent versions
      of the ninja program can build the project through the "all" target.
      An "install" target is also provided.
 
  Unix Makefiles
      Generates standard UNIX makefiles.
 
      A hierarchy of UNIX makefiles is generated into the build tree.  Any
      standard UNIX-style make program can build the project through the
      default make target.  A "make install" target is also provided.
 
  CodeBlocks - Ninja
      Generates CodeBlocks project files.
 
      Project files for CodeBlocks will be created in the top directory and
      in every subdirectory which features a CMakeLists.txt file containing
      a PROJECT() call.  Additionally a hierarchy of makefiles is generated
      into the build tree.  The appropriate make program can build the
      project through the default make target.  A "make install" target is
      also provided.

------------------------------------------------------------------------------
Commands
 
  add_custom_command
      Add a custom build rule to the generated build system.
 
      There are two main signatures for add_custom_command The first
      signature is for adding a custom command to produce an output.
 
        add_custom_command(OUTPUT output1 [output2 ...]
                            COMMAND command1 [ARGS] [args1...]
                            [COMMAND command2 [ARGS] [args2...] ...]
                            [MAIN_DEPENDENCY depend]
                            [DEPENDS [depends...]]
                            [IMPLICIT_DEPENDS <lang1> depend1 ...]
                            [WORKING_DIRECTORY dir]
                            [COMMENT comment] [VERBATIM] [APPEND])
 
      This defines a command to generate specified OUTPUT file(s).  A target
      created in the same directory (CMakeLists.txt file) that specifies any
      output of the custom command as a source file is given a rule to
      generate the file using the command at build time.  Do not list the
      output in more than one independent target that may build in parallel
      or the two instances of the rule may conflict (instead use
      add_custom_target to drive the command and make the other targets
      depend on that one).  If an output name is a relative path it will be
      interpreted relative to the build tree directory corresponding to the
      current source directory.  Note that MAIN_DEPENDENCY is completely
      optional and is used as a suggestion to visual studio about where to
      hang the custom command.  In makefile terms this creates a new target
      in the following form:
 
        OUTPUT: MAIN_DEPENDENCY DEPENDS
                COMMAND
 
      If more than one command is specified they will be executed in order.
      The optional ARGS argument is for backward compatibility and will be
      ignored.
 
      The second signature adds a custom command to a target such as a
      library or executable.  This is useful for performing an operation
      before or after building the target.  The command becomes part of the
      target and will only execute when the target itself is built.  If the
      target is already built, the command will not execute.
 
        add_custom_command(TARGET target
                            PRE_BUILD | PRE_LINK | POST_BUILD
                            COMMAND command1 [ARGS] [args1...]
                            [COMMAND command2 [ARGS] [args2...] ...]
                            [WORKING_DIRECTORY dir]
                            [COMMENT comment] [VERBATIM])
 
      This defines a new command that will be associated with building the
      specified target.  When the command will happen is determined by which
      of the following is specified:
 
        PRE_BUILD - run before all other dependencies
        PRE_LINK - run after other dependencies
        POST_BUILD - run after the target has been built
 
      Note that the PRE_BUILD option is only supported on Visual Studio 7 or
      later.  For all other generators PRE_BUILD will be treated as
      PRE_LINK.
 
      If WORKING_DIRECTORY is specified the command will be executed in the
      directory given.  If it is a relative path it will be interpreted
      relative to the build tree directory corresponding to the current
      source directory.  If COMMENT is set, the value will be displayed as a
      message before the commands are executed at build time.  If APPEND is
      specified the COMMAND and DEPENDS option values are appended to the
      custom command for the first output specified.  There must have
      already been a previous call to this command with the same output.
      The COMMENT, WORKING_DIRECTORY, and MAIN_DEPENDENCY options are
      currently ignored when APPEND is given, but may be used in the future.
 
      If VERBATIM is given then all arguments to the commands will be
      escaped properly for the build tool so that the invoked command
      receives each argument unchanged.  Note that one level of escapes is
      still used by the CMake language processor before add_custom_command
      even sees the arguments.  Use of VERBATIM is recommended as it enables
      correct behavior.  When VERBATIM is not given the behavior is platform
      specific because there is no protection of tool-specific special
      characters.
 
      If the output of the custom command is not actually created as a file
      on disk it should be marked as SYMBOLIC with
      SET_SOURCE_FILES_PROPERTIES.
 
      The IMPLICIT_DEPENDS option requests scanning of implicit dependencies
      of an input file.  The language given specifies the programming
      language whose corresponding dependency scanner should be used.
      Currently only C and CXX language scanners are supported.
      Dependencies discovered from the scanning are added to those of the
      custom command at build time.  Note that the IMPLICIT_DEPENDS option
      is currently supported only for Makefile generators and will be
      ignored by other generators.
 
      If COMMAND specifies an executable target (created by ADD_EXECUTABLE)
      it will automatically be replaced by the location of the executable
      created at build time.  Additionally a target-level dependency will be
      added so that the executable target will be built before any target
      using this custom command.  However this does NOT add a file-level
      dependency that would cause the custom command to re-run whenever the
      executable is recompiled.
 
      Arguments to COMMAND may use "generator expressions" with the syntax
      "$<...>".  Generator expressions are evaluted during build system
      generation to produce information specific to each build
      configuration.  Valid expressions are:
 
        $<0:...>                  = empty string (ignores "...")
        $<1:...>                  = content of "..."
        $<CONFIG:cfg>            = '1' if config is "cfg", else '0'
        $<CONFIGURATION>          = configuration name
        $<BOOL:...>              = '1' if the '...' is true, else '0'
        $<STREQUAL:a,b>          = '1' if a is STREQUAL b, else '0'
        $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
        $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
        $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
        $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
        $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)
 
      where "tgt" is the name of a target.  Target file expressions produce
      a full path, but _DIR and _NAME versions can produce the directory and
      file name components:
 
        $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
        $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
        $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>
 
     
 
        $<TARGET_PROPERTY:tgt,prop>  = The value of the property prop
 
      on the target tgt.  Note that tgt is not added as a dependency of
 
      the target this expression is evaluated on.
 
      Boolean expressions:
 
        $<AND:?[,?]...>          = '1' if all '?' are '1', else '0'
        $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
        $<NOT:?>                  = '0' if '?' is '1', else '1'
 
      where '?' is always either '0' or '1'.
 
      Expressions with an implicit 'this' target:
 
        $<TARGET_PROPERTY:prop>  = The value of the property prop on
 
      the target on which the generator expression is evaluated.
 
      References to target names in generator expressions imply target-level
      dependencies, but NOT file-level dependencies.  List target names with
      the DEPENDS option to add file dependencies.
 
      The DEPENDS option specifies files on which the command depends.  If
      any dependency is an OUTPUT of another custom command in the same
      directory (CMakeLists.txt file) CMake automatically brings the other
      custom command into the target in which this command is built.  If
      DEPENDS is not specified the command will run whenever the OUTPUT is
      missing; if the command does not actually create the OUTPUT then the
      rule will always run.  If DEPENDS specifies any target (created by an
      ADD_* command) a target-level dependency is created to make sure the
      target is built before any target using this custom command.
      Additionally, if the target is an executable or library a file-level
      dependency is created to cause the custom command to re-run whenever
      the target is recompiled.
 
 
  add_custom_target
      Add a target with no output so it will always be built.
 
        add_custom_target(Name [ALL] [command1 [args1...]]
                          [COMMAND command2 [args2...] ...]
                          [DEPENDS depend depend depend ... ]
                          [WORKING_DIRECTORY dir]
                          [COMMENT comment] [VERBATIM]
                          [SOURCES src1 [src2...]])
 
      Adds a target with the given name that executes the given commands.
      The target has no output file and is ALWAYS CONSIDERED OUT OF DATE
      even if the commands try to create a file with the name of the target.
      Use ADD_CUSTOM_COMMAND to generate a file with dependencies.  By
      default nothing depends on the custom target.  Use ADD_DEPENDENCIES to
      add dependencies to or from other targets.  If the ALL option is
      specified it indicates that this target should be added to the default
      build target so that it will be run every time (the command cannot be
      called ALL).  The command and arguments are optional and if not
      specified an empty target will be created.  If WORKING_DIRECTORY is
      set, then the command will be run in that directory.  If it is a
      relative path it will be interpreted relative to the build tree
      directory corresponding to the current source directory.  If COMMENT
      is set, the value will be displayed as a message before the commands
      are executed at build time.  Dependencies listed with the DEPENDS
      argument may reference files and outputs of custom commands created
      with add_custom_command() in the same directory (CMakeLists.txt file).
 
      If VERBATIM is given then all arguments to the commands will be
      escaped properly for the build tool so that the invoked command
      receives each argument unchanged.  Note that one level of escapes is
      still used by the CMake language processor before add_custom_target
      even sees the arguments.  Use of VERBATIM is recommended as it enables
      correct behavior.  When VERBATIM is not given the behavior is platform
      specific because there is no protection of tool-specific special
      characters.
 
      The SOURCES option specifies additional source files to be included in
      the custom target.  Specified source files will be added to IDE
      project files for convenience in editing even if they have not build
      rules.
 
  add_definitions
      Adds -D define flags to the compilation of source files.
 
        add_definitions(-DFOO -DBAR ...)
 
      Adds flags to the compiler command line for sources in the current
      directory and below.  This command can be used to add any flags, but
      it was originally intended to add preprocessor definitions.  Flags
      beginning in -D or /D that look like preprocessor definitions are
      automatically added to the COMPILE_DEFINITIONS property for the
      current directory.  Definitions with non-trival values may be left in
      the set of flags instead of being converted for reasons of backwards
      compatibility.  See documentation of the directory, target, and source
      file COMPILE_DEFINITIONS properties for details on adding preprocessor
      definitions to specific scopes and configurations.
 
  add_dependencies
      Add a dependency between top-level targets.
 
        add_dependencies(target-name depend-target1
                          depend-target2 ...)
 
      Make a top-level target depend on other top-level targets.  A
      top-level target is one created by ADD_EXECUTABLE, ADD_LIBRARY, or
      ADD_CUSTOM_TARGET.  Adding dependencies with this command can be used
      to make sure one target is built before another target.  Dependencies
      added to an IMPORTED target are followed transitively in its place
      since the target itself does not build.  See the DEPENDS option of
      ADD_CUSTOM_TARGET and ADD_CUSTOM_COMMAND for adding file-level
      dependencies in custom rules.  See the OBJECT_DEPENDS option in
      SET_SOURCE_FILES_PROPERTIES to add file-level dependencies to object
      files.
 
  add_executable
      Add an executable to the project using the specified source files.
 
        add_executable(<name> [WIN32] [MACOSX_BUNDLE]
                        [EXCLUDE_FROM_ALL]
                        source1 source2 ... sourceN)
 
      Adds an executable target called <name> to be built from the source
      files listed in the command invocation.  The <name> corresponds to the
      logical target name and must be globally unique within a project.  The
      actual file name of the executable built is constructed based on
      conventions of the native platform (such as <name>.exe or just
      <name>).
 
      By default the executable file will be created in the build tree
      directory corresponding to the source tree directory in which the
      command was invoked.  See documentation of the
      RUNTIME_OUTPUT_DIRECTORY target property to change this location.  See
      documentation of the OUTPUT_NAME target property to change the <name>
      part of the final file name.
 
      If WIN32 is given the property WIN32_EXECUTABLE will be set on the
      target created.  See documentation of that target property for
      details.
 
      If MACOSX_BUNDLE is given the corresponding property will be set on
      the created target.  See documentation of the MACOSX_BUNDLE target
      property for details.
 
      If EXCLUDE_FROM_ALL is given the corresponding property will be set on
      the created target.  See documentation of the EXCLUDE_FROM_ALL target
      property for details.
 
      The add_executable command can also create IMPORTED executable targets
      using this signature:
 
        add_executable(<name> IMPORTED [GLOBAL])
 
      An IMPORTED executable target references an executable file located
      outside the project.  No rules are generated to build it.  The target
      name has scope in the directory in which it is created and below, but
      the GLOBAL option extends visibility.  It may be referenced like any
      target built within the project.  IMPORTED executables are useful for
      convenient reference from commands like add_custom_command.  Details
      about the imported executable are specified by setting properties
      whose names begin in "IMPORTED_".  The most important such property is
      IMPORTED_LOCATION (and its per-configuration version
      IMPORTED_LOCATION_<CONFIG>) which specifies the location of the main
      executable file on disk.  See documentation of the IMPORTED_*
      properties for more information.
 
  add_library
      Add a library to the project using the specified source files.
 
        add_library(<name> [STATIC | SHARED | MODULE]
                    [EXCLUDE_FROM_ALL]
                    source1 source2 ... sourceN)
 
      Adds a library target called <name> to be built from the source files
      listed in the command invocation.  The <name> corresponds to the
      logical target name and must be globally unique within a project.  The
      actual file name of the library built is constructed based on
      conventions of the native platform (such as lib<name>.a or
      <name>.lib).
 
      STATIC, SHARED, or MODULE may be given to specify the type of library
      to be created.  STATIC libraries are archives of object files for use
      when linking other targets.  SHARED libraries are linked dynamically
      and loaded at runtime.  MODULE libraries are plugins that are not
      linked into other targets but may be loaded dynamically at runtime
      using dlopen-like functionality.  If no type is given explicitly the
      type is STATIC or SHARED based on whether the current value of the
      variable BUILD_SHARED_LIBS is true.  For SHARED and MODULE libraries
      the POSITION_INDEPENDENT_CODE target property is set to TRUE
      automatically.
 
      By default the library file will be created in the build tree
      directory corresponding to the source tree directory in which the
      command was invoked.  See documentation of the
      ARCHIVE_OUTPUT_DIRECTORY, LIBRARY_OUTPUT_DIRECTORY, and
      RUNTIME_OUTPUT_DIRECTORY target properties to change this location.
      See documentation of the OUTPUT_NAME target property to change the
      <name> part of the final file name.
 
      If EXCLUDE_FROM_ALL is given the corresponding property will be set on
      the created target.  See documentation of the EXCLUDE_FROM_ALL target
      property for details.
 
      The add_library command can also create IMPORTED library targets using
      this signature:
 
        add_library(<name> <SHARED|STATIC|MODULE|UNKNOWN> IMPORTED
                    [GLOBAL])
 
      An IMPORTED library target references a library file located outside
      the project.  No rules are generated to build it.  The target name has
      scope in the directory in which it is created and below, but the
      GLOBAL option extends visibility.  It may be referenced like any
      target built within the project.  IMPORTED libraries are useful for
      convenient reference from commands like target_link_libraries.
      Details about the imported library are specified by setting properties
      whose names begin in "IMPORTED_".  The most important such property is
      IMPORTED_LOCATION (and its per-configuration version
      IMPORTED_LOCATION_<CONFIG>) which specifies the location of the main
      library file on disk.  See documentation of the IMPORTED_* properties
      for more information.
 
      The signature
 
        add_library(<name> OBJECT <src>...)
 
      creates a special "object library" target.  An object library compiles
      source files but does not archive or link their object files into a
      library.  Instead other targets created by add_library or
      add_executable may reference the objects using an expression of the
      form $<TARGET_OBJECTS:objlib> as a source, where "objlib" is the
      object library name.  For example:
 
        add_library(... $<TARGET_OBJECTS:objlib> ...)
        add_executable(... $<TARGET_OBJECTS:objlib> ...)
 
      will include objlib's object files in a library and an executable
      along with those compiled from their own sources.  Object libraries
      may contain only sources (and headers) that compile to object files.
      They may contain custom commands generating such sources, but not
      PRE_BUILD, PRE_LINK, or POST_BUILD commands.  Object libraries cannot
      be imported, exported, installed, or linked.
 
  add_subdirectory
      Add a subdirectory to the build.
 
        add_subdirectory(source_dir [binary_dir]
                          [EXCLUDE_FROM_ALL])
 
      Add a subdirectory to the build.  The source_dir specifies the
      directory in which the source CmakeLists.txt and code files are
      located.  If it is a relative path it will be evaluated with respect
      to the current directory (the typical usage), but it may also be an
      absolute path.  The binary_dir specifies the directory in which to
      place the output files.  If it is a relative path it will be evaluated
      with respect to the current output directory, but it may also be an
      absolute path.  If binary_dir is not specified, the value of
      source_dir, before expanding any relative path, will be used (the
      typical usage).  The CMakeLists.txt file in the specified source
      directory will be processed immediately by CMake before processing in
      the current input file continues beyond this command.
 
      If the EXCLUDE_FROM_ALL argument is provided then targets in the
      subdirectory will not be included in the ALL target of the parent
      directory by default, and will be excluded from IDE project files.
      Users must explicitly build targets in the subdirectory.  This is
      meant for use when the subdirectory contains a separate part of the
      project that is useful but not necessary, such as a set of examples.
      Typically the subdirectory should contain its own project() command
      invocation so that a full build system will be generated in the
      subdirectory (such as a VS IDE solution file).  Note that inter-target
      dependencies supercede this exclusion.  If a target built by the
      parent project depends on a target in the subdirectory, the dependee
      target will be included in the parent project build system to satisfy
      the dependency.
 
  add_test
      Add a test to the project with the specified arguments.
 
        add_test(testname Exename arg1 arg2 ... )
 
      If the ENABLE_TESTING command has been run, this command adds a test
      target to the current directory.  If ENABLE_TESTING has not been run,
      this command does nothing.  The tests are run by the testing subsystem
      by executing Exename with the specified arguments.  Exename can be
      either an executable built by this project or an arbitrary executable
      on the system (like tclsh).  The test will be run with the current
      working directory set to the CMakeList.txt files corresponding
      directory in the binary tree.
 
     
 
        add_test(NAME <name> [CONFIGURATIONS [Debug|Release|...]]
                  [WORKING_DIRECTORY dir]
                  COMMAND <command> [arg1 [arg2 ...]])
 
      If COMMAND specifies an executable target (created by add_executable)
      it will automatically be replaced by the location of the executable
      created at build time.  If a CONFIGURATIONS option is given then the
      test will be executed only when testing under one of the named
      configurations.  If a WORKING_DIRECTORY option is given then the test
      will be executed in the given directory.
 
      Arguments after COMMAND may use "generator expressions" with the
      syntax "$<...>".  Generator expressions are evaluted during build
      system generation to produce information specific to each build
      configuration.  Valid expressions are:
 
        $<0:...>                  = empty string (ignores "...")
        $<1:...>                  = content of "..."
        $<CONFIG:cfg>            = '1' if config is "cfg", else '0'
        $<CONFIGURATION>          = configuration name
        $<BOOL:...>              = '1' if the '...' is true, else '0'
        $<STREQUAL:a,b>          = '1' if a is STREQUAL b, else '0'
        $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
        $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
        $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
        $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
        $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)
 
      where "tgt" is the name of a target.  Target file expressions produce
      a full path, but _DIR and _NAME versions can produce the directory and
      file name components:
 
        $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
        $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
        $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>
 
     
 
        $<TARGET_PROPERTY:tgt,prop>  = The value of the property prop
 
      on the target tgt.  Note that tgt is not added as a dependency of
 
      the target this expression is evaluated on.
 
      Boolean expressions:
 
        $<AND:?[,?]...>          = '1' if all '?' are '1', else '0'
        $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
        $<NOT:?>                  = '0' if '?' is '1', else '1'
 
      where '?' is always either '0' or '1'.
 
      Example usage:
 
        add_test(NAME mytest
                  COMMAND testDriver --config $<CONFIGURATION>
                                    --exe $<TARGET_FILE:myexe>)
 
      This creates a test "mytest" whose command runs a testDriver tool
      passing the configuration name and the full path to the executable
      file produced by target "myexe".
 
  aux_source_directory
      Find all source files in a directory.
 
        aux_source_directory(<dir> <variable>)
 
      Collects the names of all the source files in the specified directory
      and stores the list in the <variable> provided.  This command is
      intended to be used by projects that use explicit template
      instantiation.  Template instantiation files can be stored in a
      "Templates" subdirectory and collected automatically using this
      command to avoid manually listing all instantiations.
 
      It is tempting to use this command to avoid writing the list of source
      files for a library or executable target.  While this seems to work,
      there is no way for CMake to generate a build system that knows when a
      new source file has been added.  Normally the generated build system
      knows when it needs to rerun CMake because the CMakeLists.txt file is
      modified to add a new source.  When the source is just added to the
      directory without modifying this file, one would have to manually
      rerun CMake to generate a build system incorporating the new file.
 
  break
      Break from an enclosing foreach or while loop.
 
        break()
 
      Breaks from an enclosing foreach loop or while loop
 
  build_command
      Get the command line to build this project.
 
        build_command(<variable>
                      [CONFIGURATION <config>]
                      [PROJECT_NAME <projname>]
                      [TARGET <target>])
 
      Sets the given <variable> to a string containing the command line for
      building one configuration of a target in a project using the build
      tool appropriate for the current CMAKE_GENERATOR.
 
      If CONFIGURATION is omitted, CMake chooses a reasonable default value
      for multi-configuration generators.  CONFIGURATION is ignored for
      single-configuration generators.
 
      If PROJECT_NAME is omitted, the resulting command line will build the
      top level PROJECT in the current build tree.
 
      If TARGET is omitted, the resulting command line will build
      everything, effectively using build target 'all' or 'ALL_BUILD'.
 
        build_command(<cachevariable> <makecommand>)
 
      This second signature is deprecated, but still available for backwards
      compatibility.  Use the first signature instead.
 
      Sets the given <cachevariable> to a string containing the command to
      build this project from the root of the build tree using the build
      tool given by <makecommand>.  <makecommand> should be the full path to
      msdev, devenv, nmake, make or one of the end user build tools.
 
  cmake_minimum_required
      Set the minimum required version of cmake for a project.
 
        cmake_minimum_required(VERSION major[.minor[.patch[.tweak]]]
                                [FATAL_ERROR])
 
      If the current version of CMake is lower than that required it will
      stop processing the project and report an error.  When a version
      higher than 2.4 is specified the command implicitly invokes
 
        cmake_policy(VERSION major[.minor[.patch[.tweak]]])
 
      which sets the cmake policy version level to the version specified.
      When version 2.4 or lower is given the command implicitly invokes
 
        cmake_policy(VERSION 2.4)
 
      which enables compatibility features for CMake 2.4 and lower.
 
      The FATAL_ERROR option is accepted but ignored by CMake 2.6 and
      higher.  It should be specified so CMake versions 2.4 and lower fail
      with an error instead of just a warning.
 
  cmake_policy
      Manage CMake Policy settings.
 
      As CMake evolves it is sometimes necessary to change existing behavior
      in order to fix bugs or improve implementations of existing features.
      The CMake Policy mechanism is designed to help keep existing projects
      building as new versions of CMake introduce changes in behavior.  Each
      new policy (behavioral change) is given an identifier of the form
      "CMP<NNNN>" where "<NNNN>" is an integer index.  Documentation
      associated with each policy describes the OLD and NEW behavior and the
      reason the policy was introduced.  Projects may set each policy to
      select the desired behavior.  When CMake needs to know which behavior
      to use it checks for a setting specified by the project.  If no
      setting is available the OLD behavior is assumed and a warning is
      produced requesting that the policy be set.
 
      The cmake_policy command is used to set policies to OLD or NEW
      behavior.  While setting policies individually is supported, we
      encourage projects to set policies based on CMake versions.
 
        cmake_policy(VERSION major.minor[.patch[.tweak]])
 
      Specify that the current CMake list file is written for the given
      version of CMake.  All policies introduced in the specified version or
      earlier will be set to use NEW behavior.  All policies introduced
      after the specified version will be unset (unless variable
      CMAKE_POLICY_DEFAULT_CMP<NNNN> sets a default).  This effectively
      requests behavior preferred as of a given CMake version and tells
      newer CMake versions to warn about their new policies.  The policy
      version specified must be at least 2.4 or the command will report an
      error.  In order to get compatibility features supporting versions
      earlier than 2.4 see documentation of policy CMP0001.
 
        cmake_policy(SET CMP<NNNN> NEW)
        cmake_policy(SET CMP<NNNN> OLD)
 
      Tell CMake to use the OLD or NEW behavior for a given policy.
      Projects depending on the old behavior of a given policy may silence a
      policy warning by setting the policy state to OLD.  Alternatively one
      may fix the project to work with the new behavior and set the policy
      state to NEW.
 
        cmake_policy(GET CMP<NNNN> <variable>)
 
      Check whether a given policy is set to OLD or NEW behavior.  The
      output variable value will be "OLD" or "NEW" if the policy is set, and
      empty otherwise.
 
      CMake keeps policy settings on a stack, so changes made by the
      cmake_policy command affect only the top of the stack.  A new entry on
      the policy stack is managed automatically for each subdirectory to
      protect its parents and siblings.  CMake also manages a new entry for
      scripts loaded by include() and find_package() commands except when
      invoked with the NO_POLICY_SCOPE option (see also policy CMP0011).
      The cmake_policy command provides an interface to manage custom
      entries on the policy stack:
 
        cmake_policy(PUSH)
        cmake_policy(POP)
 
      Each PUSH must have a matching POP to erase any changes.  This is
      useful to make temporary changes to policy settings.
 
      Functions and macros record policy settings when they are created and
      use the pre-record policies when they are invoked.  If the function or
      macro implementation sets policies, the changes automatically
      propagate up through callers until they reach the closest nested
      policy stack entry.
 
  configure_file
      Copy a file to another location and modify its contents.
 
        configure_file(<input> <output>
                        [COPYONLY] [ESCAPE_QUOTES] [@ONLY]
                        [NEWLINE_STYLE [UNIX|DOS|WIN32|LF|CRLF] ])
 
      Copies a file <input> to file <output> and substitutes variable values
      referenced in the file content.  If <input> is a relative path it is
      evaluated with respect to the current source directory.  The <input>
      must be a file, not a directory.  If <output> is a relative path it is
      evaluated with respect to the current binary directory.  If <output>
      names an existing directory the input file is placed in that directory
      with its original name.
 
      This command replaces any variables in the input file referenced as
      ${VAR} or @VAR@ with their values as determined by CMake.  If a
      variable is not defined, it will be replaced with nothing.  If
      COPYONLY is specified, then no variable expansion will take place.  If
      ESCAPE_QUOTES is specified then any substituted quotes will be C-style
      escaped.  The file will be configured with the current values of CMake
      variables.  If @ONLY is specified, only variables of the form @VAR@
      will be replaces and ${VAR} will be ignored.  This is useful for
      configuring scripts that use ${VAR}.  Any occurrences of #cmakedefine
      VAR will be replaced with either #define VAR or /* #undef VAR */
      depending on the setting of VAR in CMake.  Any occurrences of
      #cmakedefine01 VAR will be replaced with either #define VAR 1 or
      #define VAR 0 depending on whether VAR evaluates to TRUE or FALSE in
      CMake.
 
      With NEWLINE_STYLE the line ending could be adjusted:
 
          'UNIX' or 'LF' for \n, 'DOS', 'WIN32' or 'CRLF' for \r\n.
 
      COPYONLY must not be used with NEWLINE_STYLE.
 
 
  create_test_sourcelist
      Create a test driver and source list for building test programs.
 
        create_test_sourcelist(sourceListName driverName
                                test1 test2 test3
                                EXTRA_INCLUDE include.h
                                FUNCTION function)
 
      A test driver is a program that links together many small tests into a
      single executable.  This is useful when building static executables
      with large libraries to shrink the total required size.  The list of
      source files needed to build the test driver will be in
      sourceListName.  DriverName is the name of the test driver program.
      The rest of the arguments consist of a list of test source files, can
      be semicolon separated.  Each test source file should have a function
      in it that is the same name as the file with no extension (foo.cxx
      should have int foo(int, char*[]);) DriverName will be able to call
      each of the tests by name on the command line.  If EXTRA_INCLUDE is
      specified, then the next argument is included into the generated file.
      If FUNCTION is specified, then the next argument is taken as a
      function name that is passed a pointer to ac and av.  This can be used
      to add extra command line processing to each test.  The cmake variable
      CMAKE_TESTDRIVER_BEFORE_TESTMAIN can be set to have code that will be
      placed directly before calling the test main function.
      CMAKE_TESTDRIVER_AFTER_TESTMAIN can be set to have code that will be
      placed directly after the call to the test main function.
 
  define_property
      Define and document custom properties.
 
        define_property(<GLOBAL | DIRECTORY | TARGET | SOURCE |
                          TEST | VARIABLE | CACHED_VARIABLE>
                          PROPERTY <name> [INHERITED]
                          BRIEF_DOCS <brief-doc> [docs...]
                          FULL_DOCS <full-doc> [docs...])
 
      Define one property in a scope for use with the set_property and
      get_property commands.  This is primarily useful to associate
      documentation with property names that may be retrieved with the
      get_property command.  The first argument determines the kind of scope
      in which the property should be used.  It must be one of the
      following:
 
        GLOBAL    = associated with the global namespace
        DIRECTORY = associated with one directory
        TARGET    = associated with one target
        SOURCE    = associated with one source file
        TEST      = associated with a test named with add_test
        VARIABLE  = documents a CMake language variable
        CACHED_VARIABLE = documents a CMake cache variable
 
      Note that unlike set_property and get_property no actual scope needs
      to be given; only the kind of scope is important.
 
      The required PROPERTY option is immediately followed by the name of
      the property being defined.
 
      If the INHERITED option then the get_property command will chain up to
      the next higher scope when the requested property is not set in the
      scope given to the command.  DIRECTORY scope chains to GLOBAL.
      TARGET, SOURCE, and TEST chain to DIRECTORY.
 
      The BRIEF_DOCS and FULL_DOCS options are followed by strings to be
      associated with the property as its brief and full documentation.
      Corresponding options to the get_property command will retrieve the
      documentation.
 
  else
      Starts the else portion of an if block.

      See the if command.
 
  enable_language
      Enable a language (CXX/C/Fortran/etc)
 
        enable_language(languageName [OPTIONAL] )
 
      This command enables support for the named language in CMake.  This is
      the same as the project command but does not create any of the extra
      variables that are created by the project command.  Example languages
      are CXX, C, Fortran.  If OPTIONAL is used, use the
      CMAKE_<languageName>_COMPILER_WORKS variable to check whether the
      language has been enabled successfully.
 
  enable_testing
      Enable testing for current directory and below.
 
        enable_testing()
 
      Enables testing for this directory and below.  See also the add_test
      command.  Note that ctest expects to find a test file in the build
      directory root.  Therefore, this command should be in the source
      directory root.

  execute_process
      Execute one or more child processes.
 
        execute_process(COMMAND <cmd1> [args1...]]
                        [COMMAND <cmd2> [args2...] [...]]
                        [WORKING_DIRECTORY <directory>]
                        [TIMEOUT <seconds>]
                        [RESULT_VARIABLE <variable>]
                        [OUTPUT_VARIABLE <variable>]
                        [ERROR_VARIABLE <variable>]
                        [INPUT_FILE <file>]
                        [OUTPUT_FILE <file>]
                        [ERROR_FILE <file>]
                        [OUTPUT_QUIET]
                        [ERROR_QUIET]
                        [OUTPUT_STRIP_TRAILING_WHITESPACE]
                        [ERROR_STRIP_TRAILING_WHITESPACE])
 
      Runs the given sequence of one or more commands with the standard
      output of each process piped to the standard input of the next.  A
      single standard error pipe is used for all processes.  If
      WORKING_DIRECTORY is given the named directory will be set as the
      current working directory of the child processes.  If TIMEOUT is given
      the child processes will be terminated if they do not finish in the
      specified number of seconds (fractions are allowed).  If
      RESULT_VARIABLE is given the variable will be set to contain the
      result of running the processes.  This will be an integer return code
      from the last child or a string describing an error condition.  If
      OUTPUT_VARIABLE or ERROR_VARIABLE are given the variable named will be
      set with the contents of the standard output and standard error pipes
      respectively.  If the same variable is named for both pipes their
      output will be merged in the order produced.  If INPUT_FILE,
      OUTPUT_FILE, or ERROR_FILE is given the file named will be attached to
      the standard input of the first process, standard output of the last
      process, or standard error of all processes respectively.  If
      OUTPUT_QUIET or ERROR_QUIET is given then the standard output or
      standard error results will be quietly ignored.  If more than one
      OUTPUT_* or ERROR_* option is given for the same pipe the precedence
      is not specified.  If no OUTPUT_* or ERROR_* options are given the
      output will be shared with the corresponding pipes of the CMake
      process itself.
 
      The execute_process command is a newer more powerful version of
      exec_program, but the old command has been kept for compatibility.
 
  export
      Export targets from the build tree for use by outside projects.
 
        export(TARGETS [target1 [target2 [...]]] [NAMESPACE <namespace>]
                [APPEND] FILE <filename>)
 
      Create a file <filename> that may be included by outside projects to
      import targets from the current project's build tree.  This is useful
      during cross-compiling to build utility executables that can run on
      the host platform in one project and then import them into another
      project being compiled for the target platform.  If the NAMESPACE
      option is given the <namespace> string will be prepended to all target
      names written to the file.  If the APPEND option is given the
      generated code will be appended to the file instead of overwriting it.
      If a library target is included in the export but a target to which it
      links is not included the behavior is unspecified.
 
      The file created by this command is specific to the build tree and
      should never be installed.  See the install(EXPORT) command to export
      targets from an installation tree.
 
      Do not set properties that affect the location of a target after
      passing it to this command.  These include properties whose names
      match "(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CONFIG>)?",
      "(IMPLIB_)?(PREFIX|SUFFIX)", or "LINKER_LANGUAGE".  Failure to follow
      this rule is not diagnosed and leaves the location of the target
      undefined.
 
        export(PACKAGE <name>)
 
      Store the current build directory in the CMake user package registry
      for package <name>.  The find_package command may consider the
      directory while searching for package <name>.  This helps dependent
      projects find and use a package from the current project's build tree
      without help from the user.  Note that the entry in the package
      registry that this command creates works only in conjunction with a
      package configuration file (<name>Config.cmake) that works with the
      build tree.
 
  file
      File manipulation command.
 
        file(WRITE filename "message to write"... )
        file(APPEND filename "message to write"... )
        file(READ filename variable [LIMIT numBytes] [OFFSET offset] [HEX])
        file(<MD5|SHA1|SHA224|SHA256|SHA384|SHA512> filename variable)
        file(STRINGS filename variable [LIMIT_COUNT num]
              [LIMIT_INPUT numBytes] [LIMIT_OUTPUT numBytes]
              [LENGTH_MINIMUM numBytes] [LENGTH_MAXIMUM numBytes]
              [NEWLINE_CONSUME] [REGEX regex]
              [NO_HEX_CONVERSION])
        file(GLOB variable [RELATIVE path] [globbing expressions]...)
        file(GLOB_RECURSE variable [RELATIVE path]
              [FOLLOW_SYMLINKS] [globbing expressions]...)
        file(RENAME <oldname> <newname>)
        file(REMOVE [file1 ...])
        file(REMOVE_RECURSE [file1 ...])
        file(MAKE_DIRECTORY [directory1 directory2 ...])
        file(RELATIVE_PATH variable directory file)
        file(TO_CMAKE_PATH path result)
        file(TO_NATIVE_PATH path result)
        file(DOWNLOAD url file [INACTIVITY_TIMEOUT timeout]
              [TIMEOUT timeout] [STATUS status] [LOG log] [SHOW_PROGRESS]
              [EXPECTED_HASH ALGO=value] [EXPECTED_MD5 sum]
              [TLS_VERIFY on|off] [TLS_CAINFO file])
        file(UPLOAD filename url [INACTIVITY_TIMEOUT timeout]
              [TIMEOUT timeout] [STATUS status] [LOG log] [SHOW_PROGRESS])
 
      WRITE will write a message into a file called 'filename'.  It
      overwrites the file if it already exists, and creates the file if it
      does not exist.
 
      APPEND will write a message into a file same as WRITE, except it will
      append it to the end of the file
 
      READ will read the content of a file and store it into the variable.
      It will start at the given offset and read up to numBytes.  If the
      argument HEX is given, the binary data will be converted to
      hexadecimal representation and this will be stored in the variable.
 
      MD5, SHA1, SHA224, SHA256, SHA384, and SHA512 will compute a
      cryptographic hash of the content of a file.
 
      STRINGS will parse a list of ASCII strings from a file and store it in
      a variable.  Binary data in the file are ignored.  Carriage return
      (CR) characters are ignored.  It works also for Intel Hex and Motorola
      S-record files, which are automatically converted to binary format
      when reading them.  Disable this using NO_HEX_CONVERSION.
 
      LIMIT_COUNT sets the maximum number of strings to return.  LIMIT_INPUT
      sets the maximum number of bytes to read from the input file.
      LIMIT_OUTPUT sets the maximum number of bytes to store in the output
      variable.  LENGTH_MINIMUM sets the minimum length of a string to
      return.  Shorter strings are ignored.  LENGTH_MAXIMUM sets the maximum
      length of a string to return.  Longer strings are split into strings
      no longer than the maximum length.  NEWLINE_CONSUME allows newlines to
      be included in strings instead of terminating them.
 
      REGEX specifies a regular expression that a string must match to be
      returned.  Typical usage
 
        file(STRINGS myfile.txt myfile)
 
      stores a list in the variable "myfile" in which each item is a line
      from the input file.
 
      GLOB will generate a list of all files that match the globbing
      expressions and store it into the variable.  Globbing expressions are
      similar to regular expressions, but much simpler.  If RELATIVE flag is
      specified for an expression, the results will be returned as a
      relative path to the given path.  (We do not recommend using GLOB to
      collect a list of source files from your source tree.  If no
      CMakeLists.txt file changes when a source is added or removed then the
      generated build system cannot know when to ask CMake to regenerate.)
 
      Examples of globbing expressions include:
 
          *.cxx      - match all files with extension cxx
          *.vt?      - match all files with extension vta,...,vtz
          f[3-5].txt - match files f3.txt, f4.txt, f5.txt
 
      GLOB_RECURSE will generate a list similar to the regular GLOB, except
      it will traverse all the subdirectories of the matched directory and
      match the files.  Subdirectories that are symlinks are only traversed
      if FOLLOW_SYMLINKS is given or cmake policy CMP0009 is not set to NEW.
      See cmake --help-policy CMP0009 for more information.
 
      Examples of recursive globbing include:
 
          /dir/*.py  - match all python files in /dir and subdirectories
 
      MAKE_DIRECTORY will create the given directories, also if their parent
      directories don't exist yet
 
      RENAME moves a file or directory within a filesystem, replacing the
      destination atomically.
 
      REMOVE will remove the given files, also in subdirectories
 
      REMOVE_RECURSE will remove the given files and directories, also
      non-empty directories
 
      RELATIVE_PATH will determine relative path from directory to the given
      file.
 
      TO_CMAKE_PATH will convert path into a cmake style path with unix /.
      The input can be a single path or a system path like "$ENV{PATH}".
      Note the double quotes around the ENV call TO_CMAKE_PATH only takes
      one argument.  This command will also convert the native list
      delimiters for a list of paths like the PATH environment variable.
 
      TO_NATIVE_PATH works just like TO_CMAKE_PATH, but will convert from a
      cmake style path into the native path style \ for windows and / for
      UNIX.
 
      DOWNLOAD will download the given URL to the given file.  If LOG var is
      specified a log of the download will be put in var.  If STATUS var is
      specified the status of the operation will be put in var.  The status
      is returned in a list of length 2.  The first element is the numeric
      return value for the operation, and the second element is a string
      value for the error.  A 0 numeric error means no error in the
      operation.  If TIMEOUT time is specified, the operation will timeout
      after time seconds, time should be specified as an integer.  The
      INACTIVITY_TIMEOUT specifies an integer number of seconds of
      inactivity after which the operation should terminate.  If
      EXPECTED_HASH ALGO=value is specified, the operation will verify that
      the downloaded file's actual hash matches the expected value, where
      ALGO is one of MD5, SHA1, SHA224, SHA256, SHA384, or SHA512.  If it
      does not match, the operation fails with an error.  ("EXPECTED_MD5
      sum" is short-hand for "EXPECTED_HASH MD5=sum".) If SHOW_PROGRESS is
      specified, progress information will be printed as status messages
      until the operation is complete.  For https URLs CMake must be built
      with OpenSSL.  TLS/SSL certificates are not checked by default.  Set
      TLS_VERIFY to ON to check certificates and/or use EXPECTED_HASH to
      verify downloaded content.  Set TLS_CAINFO to specify a custom
      Certificate Authority file.  If either TLS option is not given CMake
      will check variables CMAKE_TLS_VERIFY and CMAKE_TLS_CAINFO,
      respectively.
 
      UPLOAD will upload the given file to the given URL.  If LOG var is
      specified a log of the upload will be put in var.  If STATUS var is
      specified the status of the operation will be put in var.  The status
      is returned in a list of length 2.  The first element is the numeric
      return value for the operation, and the second element is a string
      value for the error.  A 0 numeric error means no error in the
      operation.  If TIMEOUT time is specified, the operation will timeout
      after time seconds, time should be specified as an integer.  The
      INACTIVITY_TIMEOUT specifies an integer number of seconds of
      inactivity after which the operation should terminate.  If
      SHOW_PROGRESS is specified, progress information will be printed as
      status messages until the operation is complete.
 
      The file() command also provides COPY and INSTALL signatures:
 
        file(<COPY|INSTALL> files... DESTINATION <dir>
              [FILE_PERMISSIONS permissions...]
              [DIRECTORY_PERMISSIONS permissions...]
              [NO_SOURCE_PERMISSIONS] [USE_SOURCE_PERMISSIONS]
              [FILES_MATCHING]
              [[PATTERN <pattern> | REGEX <regex>]
              [EXCLUDE] [PERMISSIONS permissions...]] [...])
 
      The COPY signature copies files, directories, and symlinks to a
      destination folder.  Relative input paths are evaluated with respect
      to the current source directory, and a relative destination is
      evaluated with respect to the current build directory.  Copying
      preserves input file timestamps, and optimizes out a file if it exists
      at the destination with the same timestamp.  Copying preserves input
      permissions unless explicit permissions or NO_SOURCE_PERMISSIONS are
      given (default is USE_SOURCE_PERMISSIONS).  See the install(DIRECTORY)
      command for documentation of permissions, PATTERN, REGEX, and EXCLUDE
      options.
 
      The INSTALL signature differs slightly from COPY: it prints status
      messages, and NO_SOURCE_PERMISSIONS is default.  Installation scripts
      generated by the install() command use this signature (with some
      undocumented options for internal use).
 
  find_file
      Find the full path to a file.
 
          find_file(<VAR> name1 [path1 path2 ...])
 
      This is the short-hand signature for the command that is sufficient in
      many cases.  It is the same as find_file(<VAR> name1 [PATHS path1
      path2 ...])
 
          find_file(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    [HINTS path1 [path2 ... ENV var]]
                    [PATHS path1 [path2 ... ENV var]]
                    [PATH_SUFFIXES suffix1 [suffix2 ...]]
                    [DOC "cache documentation string"]
                    [NO_DEFAULT_PATH]
                    [NO_CMAKE_ENVIRONMENT_PATH]
                    [NO_CMAKE_PATH]
                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_PATH]
                    [CMAKE_FIND_ROOT_PATH_BOTH |
                    ONLY_CMAKE_FIND_ROOT_PATH |
                    NO_CMAKE_FIND_ROOT_PATH]
                  )
 
      This command is used to find a full path to named file.  A cache entry
      named by <VAR> is created to store the result of this command.  If the
      full path to a file is found the result is stored in the variable and
      the search will not be repeated unless the variable is cleared.  If
      nothing is found, the result will be <VAR>-NOTFOUND, and the search
      will be attempted again the next time find_file is invoked with the
      same variable.  The name of the full path to a file that is searched
      for is specified by the names listed after the NAMES argument.
      Additional search locations can be specified after the PATHS argument.
      If ENV var is found in the HINTS or PATHS section the environment
      variable var will be read and converted from a system environment
      variable to a cmake style list of paths.  For example ENV PATH would
      be a way to list the system path variable.  The argument after DOC
      will be used for the documentation string in the cache.  PATH_SUFFIXES
      specifies additional subdirectories to check below each search path.
 
      If NO_DEFAULT_PATH is specified, then no additional paths are added to
      the search.  If NO_DEFAULT_PATH is not specified, the search process
      is as follows:
 
      1.  Search paths specified in cmake-specific cache variables.  These
      are intended to be used on the command line with a -DVAR=value.  This
      can be skipped if NO_CMAKE_PATH is passed.
 
          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH
 
      2.  Search paths specified in cmake-specific environment variables.
      These are intended to be set in the user's shell configuration.  This
      can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
 
          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH
 
      3.  Search the paths specified by the HINTS option.  These should be
      paths computed by system introspection, such as a hint provided by the
      location of another item already found.  Hard-coded guesses should be
      specified with the PATHS option.
 
      4.  Search the standard system environment variables.  This can be
      skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.
 
          PATH
          INCLUDE
 
      5.  Search cmake variables defined in the Platform files for the
      current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
      passed.
 
          <prefix>/include for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_INCLUDE_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH
 
      6.  Search the paths specified by the PATHS option or in the
      short-hand version of the command.  These are typically hard-coded
      guesses.
 
      On Darwin or systems supporting OS X Frameworks, the cmake variable
      CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:
 
          "FIRST"  - Try to find frameworks before standard
                    libraries or headers. This is the default on Darwin.
          "LAST"  - Try to find frameworks after standard
                    libraries or headers.
          "ONLY"  - Only try to find frameworks.
          "NEVER" - Never try to find frameworks.
 
      On Darwin or systems supporting OS X Application Bundles, the cmake
      variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
      following:
 
          "FIRST"  - Try to find application bundles before standard
                    programs. This is the default on Darwin.
          "LAST"  - Try to find application bundles after standard
                    programs.
          "ONLY"  - Only try to find application bundles.
          "NEVER" - Never try to find application bundles.
 
      The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
      directories to be prepended to all other search directories.  This
      effectively "re-roots" the entire search under given locations.  By
      default it is empty.  It is especially useful when cross-compiling to
      point to the root directory of the target environment and CMake will
      search there too.  By default at first the directories listed in
      CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
      searched.  The default behavior can be adjusted by setting
      CMAKE_FIND_ROOT_PATH_MODE_INCLUDE.  This behavior can be manually
      overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
      the search order will be as described above.  If
      NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
      used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
      directories will be searched.
 
      The default search order is designed to be most-specific to
      least-specific for common use cases.  Projects may override the order
      by simply calling the command multiple times and using the NO_*
      options:
 
          find_file(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_file(<VAR> NAMES name)
 
      Once one of the calls succeeds the result variable will be set and
      stored in the cache so that no call will search again.
 
  find_library
      Find a library.
 
          find_library(<VAR> name1 [path1 path2 ...])
 
      This is the short-hand signature for the command that is sufficient in
      many cases.  It is the same as find_library(<VAR> name1 [PATHS path1
      path2 ...])
 
          find_library(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    [HINTS path1 [path2 ... ENV var]]
                    [PATHS path1 [path2 ... ENV var]]
                    [PATH_SUFFIXES suffix1 [suffix2 ...]]
                    [DOC "cache documentation string"]
                    [NO_DEFAULT_PATH]
                    [NO_CMAKE_ENVIRONMENT_PATH]
                    [NO_CMAKE_PATH]
                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_PATH]
                    [CMAKE_FIND_ROOT_PATH_BOTH |
                    ONLY_CMAKE_FIND_ROOT_PATH |
                    NO_CMAKE_FIND_ROOT_PATH]
                  )
 
      This command is used to find a library.  A cache entry named by <VAR>
      is created to store the result of this command.  If the library is
      found the result is stored in the variable and the search will not be
      repeated unless the variable is cleared.  If nothing is found, the
      result will be <VAR>-NOTFOUND, and the search will be attempted again
      the next time find_library is invoked with the same variable.  The
      name of the library that is searched for is specified by the names
      listed after the NAMES argument.  Additional search locations can be
      specified after the PATHS argument.  If ENV var is found in the HINTS
      or PATHS section the environment variable var will be read and
      converted from a system environment variable to a cmake style list of
      paths.  For example ENV PATH would be a way to list the system path
      variable.  The argument after DOC will be used for the documentation
      string in the cache.  PATH_SUFFIXES specifies additional
      subdirectories to check below each search path.
 
      If NO_DEFAULT_PATH is specified, then no additional paths are added to
      the search.  If NO_DEFAULT_PATH is not specified, the search process
      is as follows:
 
      1.  Search paths specified in cmake-specific cache variables.  These
      are intended to be used on the command line with a -DVAR=value.  This
      can be skipped if NO_CMAKE_PATH is passed.
 
          <prefix>/lib/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <prefix>/lib for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_LIBRARY_PATH
          CMAKE_FRAMEWORK_PATH
 
      2.  Search paths specified in cmake-specific environment variables.
      These are intended to be set in the user's shell configuration.  This
      can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
 
          <prefix>/lib/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <prefix>/lib for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_LIBRARY_PATH
          CMAKE_FRAMEWORK_PATH
 
      3.  Search the paths specified by the HINTS option.  These should be
      paths computed by system introspection, such as a hint provided by the
      location of another item already found.  Hard-coded guesses should be
      specified with the PATHS option.
 
      4.  Search the standard system environment variables.  This can be
      skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.
 
          PATH
          LIB
 
      5.  Search cmake variables defined in the Platform files for the
      current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
      passed.
 
          <prefix>/lib/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <prefix>/lib for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_LIBRARY_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH
 
      6.  Search the paths specified by the PATHS option or in the
      short-hand version of the command.  These are typically hard-coded
      guesses.
 
      On Darwin or systems supporting OS X Frameworks, the cmake variable
      CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:
 
          "FIRST"  - Try to find frameworks before standard
                    libraries or headers. This is the default on Darwin.
          "LAST"  - Try to find frameworks after standard
                    libraries or headers.
          "ONLY"  - Only try to find frameworks.
          "NEVER" - Never try to find frameworks.
 
      On Darwin or systems supporting OS X Application Bundles, the cmake
      variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
      following:
 
          "FIRST"  - Try to find application bundles before standard
                    programs. This is the default on Darwin.
          "LAST"  - Try to find application bundles after standard
                    programs.
          "ONLY"  - Only try to find application bundles.
          "NEVER" - Never try to find application bundles.
 
      The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
      directories to be prepended to all other search directories.  This
      effectively "re-roots" the entire search under given locations.  By
      default it is empty.  It is especially useful when cross-compiling to
      point to the root directory of the target environment and CMake will
      search there too.  By default at first the directories listed in
      CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
      searched.  The default behavior can be adjusted by setting
      CMAKE_FIND_ROOT_PATH_MODE_LIBRARY.  This behavior can be manually
      overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
      the search order will be as described above.  If
      NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
      used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
      directories will be searched.
 
      The default search order is designed to be most-specific to
      least-specific for common use cases.  Projects may override the order
      by simply calling the command multiple times and using the NO_*
      options:
 
          find_library(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_library(<VAR> NAMES name)
 
      Once one of the calls succeeds the result variable will be set and
      stored in the cache so that no call will search again.
 
      If the library found is a framework, then VAR will be set to the full
      path to the framework <fullPath>/A.framework.  When a full path to a
      framework is used as a library, CMake will use a -framework A, and a
      -F<fullPath> to link the framework to the target.
 
      If the global property FIND_LIBRARY_USE_LIB64_PATHS is set all search
      paths will be tested as normal, with "64/" appended, and with all
      matches of "lib/" replaced with "lib64/".  This property is
      automatically set for the platforms that are known to need it if at
      least one of the languages supported by the PROJECT command is
      enabled.
 
  find_package
      Load settings for an external project.
 
        find_package(<package> [version] [EXACT] [QUIET] [MODULE]
                      [REQUIRED] [[COMPONENTS] [components...]]
                      [OPTIONAL_COMPONENTS components...]
                      [NO_POLICY_SCOPE])
 
      Finds and loads settings from an external project.  <package>_FOUND
      will be set to indicate whether the package was found.  When the
      package is found package-specific information is provided through
      variables documented by the package itself.  The QUIET option disables
      messages if the package cannot be found.  The MODULE option disables
      the second signature documented below.  The REQUIRED option stops
      processing with an error message if the package cannot be found.
 
      A package-specific list of required components may be listed after the
      COMPONENTS option (or after the REQUIRED option if present).
      Additional optional components may be listed after
      OPTIONAL_COMPONENTS.  Available components and their influence on
      whether a package is considered to be found are defined by the target
      package.
 
      The [version] argument requests a version with which the package found
      should be compatible (format is major[.minor[.patch[.tweak]]]).  The
      EXACT option requests that the version be matched exactly.  If no
      [version] and/or component list is given to a recursive invocation
      inside a find-module, the corresponding arguments are forwarded
      automatically from the outer call (including the EXACT flag for
      [version]).  Version support is currently provided only on a
      package-by-package basis (details below).
 
      User code should generally look for packages using the above simple
      signature.  The remainder of this command documentation specifies the
      full command signature and details of the search process.  Project
      maintainers wishing to provide a package to be found by this command
      are encouraged to read on.
 
      The command has two modes by which it searches for packages: "Module"
      mode and "Config" mode.  Module mode is available when the command is
      invoked with the above reduced signature.  CMake searches for a file
      called "Find<package>.cmake" in the CMAKE_MODULE_PATH followed by the
      CMake installation.  If the file is found, it is read and processed by
      CMake.  It is responsible for finding the package, checking the
      version, and producing any needed messages.  Many find-modules provide
      limited or no support for versioning; check the module documentation.
      If no module is found and the MODULE option is not given the command
      proceeds to Config mode.
 
      The complete Config mode command signature is:
 
        find_package(<package> [version] [EXACT] [QUIET]
                      [REQUIRED] [[COMPONENTS] [components...]]
                      [CONFIG|NO_MODULE]
                      [NO_POLICY_SCOPE]
                      [NAMES name1 [name2 ...]]
                      [CONFIGS config1 [config2 ...]]
                      [HINTS path1 [path2 ... ]]
                      [PATHS path1 [path2 ... ]]
                      [PATH_SUFFIXES suffix1 [suffix2 ...]]
                      [NO_DEFAULT_PATH]
                      [NO_CMAKE_ENVIRONMENT_PATH]
                      [NO_CMAKE_PATH]
                      [NO_SYSTEM_ENVIRONMENT_PATH]
                      [NO_CMAKE_PACKAGE_REGISTRY]
                      [NO_CMAKE_BUILDS_PATH]
                      [NO_CMAKE_SYSTEM_PATH]
                      [NO_CMAKE_SYSTEM_PACKAGE_REGISTRY]
                      [CMAKE_FIND_ROOT_PATH_BOTH |
                      ONLY_CMAKE_FIND_ROOT_PATH |
                      NO_CMAKE_FIND_ROOT_PATH])
 
      The CONFIG option may be used to skip Module mode explicitly and
      switch to Config mode.  It is synonymous to using NO_MODULE.  Config
      mode is also implied by use of options not specified in the reduced
      signature.
 
      Config mode attempts to locate a configuration file provided by the
      package to be found.  A cache entry called <package>_DIR is created to
      hold the directory containing the file.  By default the command
      searches for a package with the name <package>.  If the NAMES option
      is given the names following it are used instead of <package>.  The
      command searches for a file called "<name>Config.cmake" or
      "<lower-case-name>-config.cmake" for each name specified.  A
      replacement set of possible configuration file names may be given
      using the CONFIGS option.  The search procedure is specified below.
      Once found, the configuration file is read and processed by CMake.
      Since the file is provided by the package it already knows the
      location of package contents.  The full path to the configuration file
      is stored in the cmake variable <package>_CONFIG.
 
      All configuration files which have been considered by CMake while
      searching for an installation of the package with an appropriate
      version are stored in the cmake variable <package>_CONSIDERED_CONFIGS,
      the associated versions in <package>_CONSIDERED_VERSIONS.
 
      If the package configuration file cannot be found CMake will generate
      an error describing the problem unless the QUIET argument is
      specified.  If REQUIRED is specified and the package is not found a
      fatal error is generated and the configure step stops executing.  If
      <package>_DIR has been set to a directory not containing a
      configuration file CMake will ignore it and search from scratch.
 
      When the [version] argument is given Config mode will only find a
      version of the package that claims compatibility with the requested
      version (format is major[.minor[.patch[.tweak]]]).  If the EXACT
      option is given only a version of the package claiming an exact match
      of the requested version may be found.  CMake does not establish any
      convention for the meaning of version numbers.  Package version
      numbers are checked by "version" files provided by the packages
      themselves.  For a candidate package configuration file
      "<config-file>.cmake" the corresponding version file is located next
      to it and named either "<config-file>-version.cmake" or
      "<config-file>Version.cmake".  If no such version file is available
      then the configuration file is assumed to not be compatible with any
      requested version.  A basic version file containing generic version
      matching code can be created using the macro
      write_basic_package_version_file(), see its documentation for more
      details.  When a version file is found it is loaded to check the
      requested version number.  The version file is loaded in a nested
      scope in which the following variables have been defined:
 
        PACKAGE_FIND_NAME          = the <package> name
        PACKAGE_FIND_VERSION      = full requested version string
        PACKAGE_FIND_VERSION_MAJOR = major version if requested, else 0
        PACKAGE_FIND_VERSION_MINOR = minor version if requested, else 0
        PACKAGE_FIND_VERSION_PATCH = patch version if requested, else 0
        PACKAGE_FIND_VERSION_TWEAK = tweak version if requested, else 0
        PACKAGE_FIND_VERSION_COUNT = number of version components, 0 to 4
 
      The version file checks whether it satisfies the requested version and
      sets these variables:
 
        PACKAGE_VERSION            = full provided version string
        PACKAGE_VERSION_EXACT      = true if version is exact match
        PACKAGE_VERSION_COMPATIBLE = true if version is compatible
        PACKAGE_VERSION_UNSUITABLE = true if unsuitable as any version
 
      These variables are checked by the find_package command to determine
      whether the configuration file provides an acceptable version.  They
      are not available after the find_package call returns.  If the version
      is acceptable the following variables are set:
 
        <package>_VERSION      = full provided version string
        <package>_VERSION_MAJOR = major version if provided, else 0
        <package>_VERSION_MINOR = minor version if provided, else 0
        <package>_VERSION_PATCH = patch version if provided, else 0
        <package>_VERSION_TWEAK = tweak version if provided, else 0
        <package>_VERSION_COUNT = number of version components, 0 to 4
 
      and the corresponding package configuration file is loaded.  When
      multiple package configuration files are available whose version files
      claim compatibility with the version requested it is unspecified which
      one is chosen.  No attempt is made to choose a highest or closest
      version number.
 
      Config mode provides an elaborate interface and search procedure.
      Much of the interface is provided for completeness and for use
      internally by find-modules loaded by Module mode.  Most user code
      should simply call
 
        find_package(<package> [major[.minor]] [EXACT] [REQUIRED|QUIET])
 
      in order to find a package.  Package maintainers providing CMake
      package configuration files are encouraged to name and install them
      such that the procedure outlined below will find them without
      requiring use of additional options.
 
      CMake constructs a set of possible installation prefixes for the
      package.  Under each prefix several directories are searched for a
      configuration file.  The tables below show the directories searched.
      Each entry is meant for installation trees following Windows (W), UNIX
      (U), or Apple (A) conventions.
 
        <prefix>/                                              (W)
        <prefix>/(cmake|CMake)/                                (W)
        <prefix>/<name>*/                                      (W)
        <prefix>/<name>*/(cmake|CMake)/                        (W)
        <prefix>/(lib/<arch>|lib|share)/cmake/<name>*/          (U)
        <prefix>/(lib/<arch>|lib|share)/<name>*/                (U)
        <prefix>/(lib/<arch>|lib|share)/<name>*/(cmake|CMake)/  (U)
 
      On systems supporting OS X Frameworks and Application Bundles the
      following directories are searched for frameworks or bundles
      containing a configuration file:
 
        <prefix>/<name>.framework/Resources/                    (A)
        <prefix>/<name>.framework/Resources/CMake/              (A)
        <prefix>/<name>.framework/Versions/*/Resources/        (A)
        <prefix>/<name>.framework/Versions/*/Resources/CMake/  (A)
        <prefix>/<name>.app/Contents/Resources/                (A)
        <prefix>/<name>.app/Contents/Resources/CMake/          (A)
 
      In all cases the <name> is treated as case-insensitive and corresponds
      to any of the names specified (<package> or names given by NAMES).
      Paths with lib/<arch> are enabled if CMAKE_LIBRARY_ARCHITECTURE is
      set.  If PATH_SUFFIXES is specified the suffixes are appended to each
      (W) or (U) directory entry one-by-one.
 
      This set of directories is intended to work in cooperation with
      projects that provide configuration files in their installation trees.
      Directories above marked with (W) are intended for installations on
      Windows where the prefix may point at the top of an application's
      installation directory.  Those marked with (U) are intended for
      installations on UNIX platforms where the prefix is shared by multiple
      packages.  This is merely a convention, so all (W) and (U) directories
      are still searched on all platforms.  Directories marked with (A) are
      intended for installations on Apple platforms.  The cmake variables
      CMAKE_FIND_FRAMEWORK and CMAKE_FIND_APPBUNDLE determine the order of
      preference as specified below.
 
      The set of installation prefixes is constructed using the following
      steps.  If NO_DEFAULT_PATH is specified all NO_* options are enabled.
 
      1.  Search paths specified in cmake-specific cache variables.  These
      are intended to be used on the command line with a -DVAR=value.  This
      can be skipped if NO_CMAKE_PATH is passed.
 
          CMAKE_PREFIX_PATH
          CMAKE_FRAMEWORK_PATH
          CMAKE_APPBUNDLE_PATH
 
      2.  Search paths specified in cmake-specific environment variables.
      These are intended to be set in the user's shell configuration.  This
      can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
 
          <package>_DIR
          CMAKE_PREFIX_PATH
          CMAKE_FRAMEWORK_PATH
          CMAKE_APPBUNDLE_PATH
 
      3.  Search paths specified by the HINTS option.  These should be paths
      computed by system introspection, such as a hint provided by the
      location of another item already found.  Hard-coded guesses should be
      specified with the PATHS option.
 
      4.  Search the standard system environment variables.  This can be
      skipped if NO_SYSTEM_ENVIRONMENT_PATH is passed.  Path entries ending
      in "/bin" or "/sbin" are automatically converted to their parent
      directories.
 
          PATH
 
      5.  Search project build trees recently configured in a CMake GUI.
      This can be skipped if NO_CMAKE_BUILDS_PATH is passed.  It is intended
      for the case when a user is building multiple dependent projects one
      after another.
 
      6.  Search paths stored in the CMake user package registry.  This can
      be skipped if NO_CMAKE_PACKAGE_REGISTRY is passed.  On Windows a
      <package> may appear under registry key
 
        HKEY_CURRENT_USER\Software\Kitware\CMake\Packages\<package>
 
      as a REG_SZ value, with arbitrary name, that specifies the directory
      containing the package configuration file.  On UNIX platforms a
      <package> may appear under the directory
 
        ~/.cmake/packages/<package>
 
      as a file, with arbitrary name, whose content specifies the directory
      containing the package configuration file.  See the export(PACKAGE)
      command to create user package registry entries for project build
      trees.
 
      7.  Search cmake variables defined in the Platform files for the
      current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
      passed.
 
          CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH
          CMAKE_SYSTEM_APPBUNDLE_PATH
 
      8.  Search paths stored in the CMake system package registry.  This
      can be skipped if NO_CMAKE_SYSTEM_PACKAGE_REGISTRY is passed.  On
      Windows a <package> may appear under registry key
 
        HKEY_LOCAL_MACHINE\Software\Kitware\CMake\Packages\<package>
 
      as a REG_SZ value, with arbitrary name, that specifies the directory
      containing the package configuration file.  There is no system package
      registry on non-Windows platforms.
 
      9.  Search paths specified by the PATHS option.  These are typically
      hard-coded guesses.
 
      On Darwin or systems supporting OS X Frameworks, the cmake variable
      CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:
 
          "FIRST"  - Try to find frameworks before standard
                    libraries or headers. This is the default on Darwin.
          "LAST"  - Try to find frameworks after standard
                    libraries or headers.
          "ONLY"  - Only try to find frameworks.
          "NEVER" - Never try to find frameworks.
 
      On Darwin or systems supporting OS X Application Bundles, the cmake
      variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
      following:
 
          "FIRST"  - Try to find application bundles before standard
                    programs. This is the default on Darwin.
          "LAST"  - Try to find application bundles after standard
                    programs.
          "ONLY"  - Only try to find application bundles.
          "NEVER" - Never try to find application bundles.
 
      The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
      directories to be prepended to all other search directories.  This
      effectively "re-roots" the entire search under given locations.  By
      default it is empty.  It is especially useful when cross-compiling to
      point to the root directory of the target environment and CMake will
      search there too.  By default at first the directories listed in
      CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
      searched.  The default behavior can be adjusted by setting
      CMAKE_FIND_ROOT_PATH_MODE_PACKAGE.  This behavior can be manually
      overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
      the search order will be as described above.  If
      NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
      used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
      directories will be searched.
 
      The default search order is designed to be most-specific to
      least-specific for common use cases.  Projects may override the order
      by simply calling the command multiple times and using the NO_*
      options:
 
          find_package(<package> PATHS paths... NO_DEFAULT_PATH)
          find_package(<package>)
 
      Once one of the calls succeeds the result variable will be set and
      stored in the cache so that no call will search again.
 
      Every non-REQUIRED find_package() call can be disabled by setting the
      variable CMAKE_DISABLE_FIND_PACKAGE_<package> to TRUE.  See the
      documentation for the CMAKE_DISABLE_FIND_PACKAGE_<package> variable
      for more information.
 
      When loading a find module or package configuration file find_package
      defines variables to provide information about the call arguments (and
      restores their original state before returning):
 
        <package>_FIND_REQUIRED      = true if REQUIRED option was given
        <package>_FIND_QUIETLY      = true if QUIET option was given
        <package>_FIND_VERSION      = full requested version string
        <package>_FIND_VERSION_MAJOR = major version if requested, else 0
        <package>_FIND_VERSION_MINOR = minor version if requested, else 0
        <package>_FIND_VERSION_PATCH = patch version if requested, else 0
        <package>_FIND_VERSION_TWEAK = tweak version if requested, else 0
        <package>_FIND_VERSION_COUNT = number of version components, 0 to 4
        <package>_FIND_VERSION_EXACT = true if EXACT option was given
        <package>_FIND_COMPONENTS    = list of requested components
        <package>_FIND_REQUIRED_<c>  = true if component <c> is required
                                      false if component <c> is optional
 
      In Module mode the loaded find module is responsible to honor the
      request detailed by these variables; see the find module for details.
      In Config mode find_package handles REQUIRED, QUIET, and version
      options automatically but leaves it to the package configuration file
      to handle components in a way that makes sense for the package.  The
      package configuration file may set <package>_FOUND to false to tell
      find_package that component requirements are not satisfied.
 
      See the cmake_policy() command documentation for discussion of the
      NO_POLICY_SCOPE option.
 
  find_path
      Find the directory containing a file.
 
          find_path(<VAR> name1 [path1 path2 ...])
 
      This is the short-hand signature for the command that is sufficient in
      many cases.  It is the same as find_path(<VAR> name1 [PATHS path1
      path2 ...])
 
          find_path(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    [HINTS path1 [path2 ... ENV var]]
                    [PATHS path1 [path2 ... ENV var]]
                    [PATH_SUFFIXES suffix1 [suffix2 ...]]
                    [DOC "cache documentation string"]
                    [NO_DEFAULT_PATH]
                    [NO_CMAKE_ENVIRONMENT_PATH]
                    [NO_CMAKE_PATH]
                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_PATH]
                    [CMAKE_FIND_ROOT_PATH_BOTH |
                    ONLY_CMAKE_FIND_ROOT_PATH |
                    NO_CMAKE_FIND_ROOT_PATH]
                  )
 
      This command is used to find a directory containing the named file.  A
      cache entry named by <VAR> is created to store the result of this
      command.  If the file in a directory is found the result is stored in
      the variable and the search will not be repeated unless the variable
      is cleared.  If nothing is found, the result will be <VAR>-NOTFOUND,
      and the search will be attempted again the next time find_path is
      invoked with the same variable.  The name of the file in a directory
      that is searched for is specified by the names listed after the NAMES
      argument.  Additional search locations can be specified after the
      PATHS argument.  If ENV var is found in the HINTS or PATHS section the
      environment variable var will be read and converted from a system
      environment variable to a cmake style list of paths.  For example ENV
      PATH would be a way to list the system path variable.  The argument
      after DOC will be used for the documentation string in the cache.
      PATH_SUFFIXES specifies additional subdirectories to check below each
      search path.
 
      If NO_DEFAULT_PATH is specified, then no additional paths are added to
      the search.  If NO_DEFAULT_PATH is not specified, the search process
      is as follows:
 
      1.  Search paths specified in cmake-specific cache variables.  These
      are intended to be used on the command line with a -DVAR=value.  This
      can be skipped if NO_CMAKE_PATH is passed.
 
          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH
 
      2.  Search paths specified in cmake-specific environment variables.
      These are intended to be set in the user's shell configuration.  This
      can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
 
          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH
 
      3.  Search the paths specified by the HINTS option.  These should be
      paths computed by system introspection, such as a hint provided by the
      location of another item already found.  Hard-coded guesses should be
      specified with the PATHS option.
 
      4.  Search the standard system environment variables.  This can be
      skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.
 
          PATH
          INCLUDE
 
      5.  Search cmake variables defined in the Platform files for the
      current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
      passed.
 
          <prefix>/include for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_INCLUDE_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH
 
      6.  Search the paths specified by the PATHS option or in the
      short-hand version of the command.  These are typically hard-coded
      guesses.
 
      On Darwin or systems supporting OS X Frameworks, the cmake variable
      CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:
 
          "FIRST"  - Try to find frameworks before standard
                    libraries or headers. This is the default on Darwin.
          "LAST"  - Try to find frameworks after standard
                    libraries or headers.
          "ONLY"  - Only try to find frameworks.
          "NEVER" - Never try to find frameworks.
 
      On Darwin or systems supporting OS X Application Bundles, the cmake
      variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
      following:
 
          "FIRST"  - Try to find application bundles before standard
                    programs. This is the default on Darwin.
          "LAST"  - Try to find application bundles after standard
                    programs.
          "ONLY"  - Only try to find application bundles.
          "NEVER" - Never try to find application bundles.
 
      The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
      directories to be prepended to all other search directories.  This
      effectively "re-roots" the entire search under given locations.  By
      default it is empty.  It is especially useful when cross-compiling to
      point to the root directory of the target environment and CMake will
      search there too.  By default at first the directories listed in
      CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
      searched.  The default behavior can be adjusted by setting
      CMAKE_FIND_ROOT_PATH_MODE_INCLUDE.  This behavior can be manually
      overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
      the search order will be as described above.  If
      NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
      used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
      directories will be searched.
 
      The default search order is designed to be most-specific to
      least-specific for common use cases.  Projects may override the order
      by simply calling the command multiple times and using the NO_*
      options:
 
          find_path(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_path(<VAR> NAMES name)
 
      Once one of the calls succeeds the result variable will be set and
      stored in the cache so that no call will search again.
 
      When searching for frameworks, if the file is specified as A/b.h, then
      the framework search will look for A.framework/Headers/b.h.  If that
      is found the path will be set to the path to the framework.  CMake
      will convert this to the correct -F option to include the file.
 
  find_program
      Find an executable program.
 
          find_program(<VAR> name1 [path1 path2 ...])
 
      This is the short-hand signature for the command that is sufficient in
      many cases.  It is the same as find_program(<VAR> name1 [PATHS path1
      path2 ...])
 
          find_program(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    [HINTS path1 [path2 ... ENV var]]
                    [PATHS path1 [path2 ... ENV var]]
                    [PATH_SUFFIXES suffix1 [suffix2 ...]]
                    [DOC "cache documentation string"]
                    [NO_DEFAULT_PATH]
                    [NO_CMAKE_ENVIRONMENT_PATH]
                    [NO_CMAKE_PATH]
                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_PATH]
                    [CMAKE_FIND_ROOT_PATH_BOTH |
                    ONLY_CMAKE_FIND_ROOT_PATH |
                    NO_CMAKE_FIND_ROOT_PATH]
                  )
 
      This command is used to find a program.  A cache entry named by <VAR>
      is created to store the result of this command.  If the program is
      found the result is stored in the variable and the search will not be
      repeated unless the variable is cleared.  If nothing is found, the
      result will be <VAR>-NOTFOUND, and the search will be attempted again
      the next time find_program is invoked with the same variable.  The
      name of the program that is searched for is specified by the names
      listed after the NAMES argument.  Additional search locations can be
      specified after the PATHS argument.  If ENV var is found in the HINTS
      or PATHS section the environment variable var will be read and
      converted from a system environment variable to a cmake style list of
      paths.  For example ENV PATH would be a way to list the system path
      variable.  The argument after DOC will be used for the documentation
      string in the cache.  PATH_SUFFIXES specifies additional
      subdirectories to check below each search path.
 
      If NO_DEFAULT_PATH is specified, then no additional paths are added to
      the search.  If NO_DEFAULT_PATH is not specified, the search process
      is as follows:
 
      1.  Search paths specified in cmake-specific cache variables.  These
      are intended to be used on the command line with a -DVAR=value.  This
      can be skipped if NO_CMAKE_PATH is passed.
 
          <prefix>/[s]bin for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_PROGRAM_PATH
          CMAKE_APPBUNDLE_PATH
 
      2.  Search paths specified in cmake-specific environment variables.
      These are intended to be set in the user's shell configuration.  This
      can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
 
          <prefix>/[s]bin for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_PROGRAM_PATH
          CMAKE_APPBUNDLE_PATH
 
      3.  Search the paths specified by the HINTS option.  These should be
      paths computed by system introspection, such as a hint provided by the
      location of another item already found.  Hard-coded guesses should be
      specified with the PATHS option.
 
      4.  Search the standard system environment variables.  This can be
      skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.
 
          PATH
         
 
      5.  Search cmake variables defined in the Platform files for the
      current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
      passed.
 
          <prefix>/[s]bin for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_PROGRAM_PATH
          CMAKE_SYSTEM_APPBUNDLE_PATH
 
      6.  Search the paths specified by the PATHS option or in the
      short-hand version of the command.  These are typically hard-coded
      guesses.
 
      On Darwin or systems supporting OS X Frameworks, the cmake variable
      CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:
 
          "FIRST"  - Try to find frameworks before standard
                    libraries or headers. This is the default on Darwin.
          "LAST"  - Try to find frameworks after standard
                    libraries or headers.
          "ONLY"  - Only try to find frameworks.
          "NEVER" - Never try to find frameworks.
 
      On Darwin or systems supporting OS X Application Bundles, the cmake
      variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
      following:
 
          "FIRST"  - Try to find application bundles before standard
                    programs. This is the default on Darwin.
          "LAST"  - Try to find application bundles after standard
                    programs.
          "ONLY"  - Only try to find application bundles.
          "NEVER" - Never try to find application bundles.
 
      The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
      directories to be prepended to all other search directories.  This
      effectively "re-roots" the entire search under given locations.  By
      default it is empty.  It is especially useful when cross-compiling to
      point to the root directory of the target environment and CMake will
      search there too.  By default at first the directories listed in
      CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
      searched.  The default behavior can be adjusted by setting
      CMAKE_FIND_ROOT_PATH_MODE_PROGRAM.  This behavior can be manually
      overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
      the search order will be as described above.  If
      NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
      used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
      directories will be searched.
 
      The default search order is designed to be most-specific to
      least-specific for common use cases.  Projects may override the order
      by simply calling the command multiple times and using the NO_*
      options:
 
          find_program(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_program(<VAR> NAMES name)
 
      Once one of the calls succeeds the result variable will be set and
      stored in the cache so that no call will search again.
 
  fltk_wrap_ui
      Create FLTK user interfaces Wrappers.
 
        fltk_wrap_ui(resultingLibraryName source1
                      source2 ... sourceN )
 
      Produce .h and .cxx files for all the .fl and .fld files listed.  The
      resulting .h and .cxx files will be added to a variable named
      resultingLibraryName_FLTK_UI_SRCS which should be added to your
      library.
 
  foreach
      Evaluate a group of commands for each value in a list.
 
        foreach(loop_var arg1 arg2 ...)
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        endforeach(loop_var)
 
      All commands between foreach and the matching endforeach are recorded
      without being invoked.  Once the endforeach is evaluated, the recorded
      list of commands is invoked once for each argument listed in the
      original foreach command.  Before each iteration of the loop
      "${loop_var}" will be set as a variable with the current value in the
      list.
 
        foreach(loop_var RANGE total)
        foreach(loop_var RANGE start stop [step])
 
      Foreach can also iterate over a generated range of numbers.  There are
      three types of this iteration:
 
      * When specifying single number, the range will have elements 0 to
      "total".
 
      * When specifying two numbers, the range will have elements from the
      first number to the second number.
 
      * The third optional number is the increment used to iterate from the
      first number to the second number.
 
        foreach(loop_var IN [LISTS [list1 [...]]]
                            [ITEMS [item1 [...]]])
 
      Iterates over a precise list of items.  The LISTS option names
      list-valued variables to be traversed, including empty elements (an
      empty string is a zero-length list).  The ITEMS option ends argument
      parsing and includes all arguments following it in the iteration.
 
  function
      Start recording a function for later invocation as a command.
 
        function(<name> [arg1 [arg2 [arg3 ...]]])
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        endfunction(<name>)
 
      Define a function named <name> that takes arguments named arg1 arg2
      arg3 (...).  Commands listed after function, but before the matching
      endfunction, are not invoked until the function is invoked.  When it
      is invoked, the commands recorded in the function are first modified
      by replacing formal parameters (${arg1}) with the arguments passed,
      and then invoked as normal commands.  In addition to referencing the
      formal parameters you can reference the variable ARGC which will be
      set to the number of arguments passed into the function as well as
      ARGV0 ARGV1 ARGV2 ...  which will have the actual values of the
      arguments passed in.  This facilitates creating functions with
      optional arguments.  Additionally ARGV holds the list of all arguments
      given to the function and ARGN holds the list of argument past the
      last expected argument.
 
      See the cmake_policy() command documentation for the behavior of
      policies inside functions.
 
  get_cmake_property
      Get a property of the CMake instance.
 
        get_cmake_property(VAR property)
 
      Get a property from the CMake instance.  The value of the property is
      stored in the variable VAR.  If the property is not found, VAR will be
      set to "NOTFOUND".  Some supported properties include: VARIABLES,
      CACHE_VARIABLES, COMMANDS, MACROS, and COMPONENTS.
 
      See also the more general get_property() command.
 
  get_directory_property
      Get a property of DIRECTORY scope.
 
        get_directory_property(<variable> [DIRECTORY <dir>] <prop-name>)
 
      Store a property of directory scope in the named variable.  If the
      property is not defined the empty-string is returned.  The DIRECTORY
      argument specifies another directory from which to retrieve the
      property value.  The specified directory must have already been
      traversed by CMake.
 
        get_directory_property(<variable> [DIRECTORY <dir>]
                                DEFINITION <var-name>)
 
      Get a variable definition from a directory.  This form is useful to
      get a variable definition from another directory.
 
      See also the more general get_property() command.
 
  get_filename_component
      Get a specific component of a full filename.
 
        get_filename_component(<VAR> FileName
                                PATH|ABSOLUTE|NAME|EXT|NAME_WE|REALPATH
                                [CACHE])
 
      Set <VAR> to be the path (PATH), file name (NAME), file extension
      (EXT), file name without extension (NAME_WE) of FileName, the full
      path (ABSOLUTE), or the full path with all symlinks resolved
      (REALPATH).  Note that the path is converted to Unix slashes format
      and has no trailing slashes.  The longest file extension is always
      considered.  If the optional CACHE argument is specified, the result
      variable is added to the cache.
 
        get_filename_component(<VAR> FileName
                                PROGRAM [PROGRAM_ARGS <ARG_VAR>]
                                [CACHE])
 
      The program in FileName will be found in the system search path or
      left as a full path.  If PROGRAM_ARGS is present with PROGRAM, then
      any command-line arguments present in the FileName string are split
      from the program name and stored in <ARG_VAR>.  This is used to
      separate a program name from its arguments in a command line string.
 
  get_property
      Get a property.
 
        get_property(<variable>
                      <GLOBAL            |
                      DIRECTORY [dir]    |
                      TARGET    <target> |
                      SOURCE    <source> |
                      TEST      <test>  |
                      CACHE    <entry>  |
                      VARIABLE>
                      PROPERTY <name>
                      [SET | DEFINED | BRIEF_DOCS | FULL_DOCS])
 
      Get one property from one object in a scope.  The first argument
      specifies the variable in which to store the result.  The second
      argument determines the scope from which to get the property.  It must
      be one of the following:
 
      GLOBAL scope is unique and does not accept a name.
 
      DIRECTORY scope defaults to the current directory but another
      directory (already processed by CMake) may be named by full or
      relative path.
 
      TARGET scope must name one existing target.
 
      SOURCE scope must name one source file.
 
      TEST scope must name one existing test.
 
      CACHE scope must name one cache entry.
 
      VARIABLE scope is unique and does not accept a name.
 
      The required PROPERTY option is immediately followed by the name of
      the property to get.  If the property is not set an empty value is
      returned.  If the SET option is given the variable is set to a boolean
      value indicating whether the property has been set.  If the DEFINED
      option is given the variable is set to a boolean value indicating
      whether the property has been defined such as with define_property.
      If BRIEF_DOCS or FULL_DOCS is given then the variable is set to a
      string containing documentation for the requested property.  If
      documentation is requested for a property that has not been defined
      NOTFOUND is returned.
 
  get_source_file_property
      Get a property for a source file.
 
        get_source_file_property(VAR file property)
 
      Get a property from a source file.  The value of the property is
      stored in the variable VAR.  If the property is not found, VAR will be
      set to "NOTFOUND".  Use set_source_files_properties to set property
      values.  Source file properties usually control how the file is built.
      One property that is always there is LOCATION
 
      See also the more general get_property() command.
 
  get_target_property
      Get a property from a target.
 
        get_target_property(VAR target property)
 
      Get a property from a target.  The value of the property is stored in
      the variable VAR.  If the property is not found, VAR will be set to
      "NOTFOUND".  Use set_target_properties to set property values.
      Properties are usually used to control how a target is built, but some
      query the target instead.  This command can get properties for any
      target so far created.  The targets do not need to be in the current
      CMakeLists.txt file.
 
      See also the more general get_property() command.
 
  get_test_property
      Get a property of the test.
 
        get_test_property(test property VAR)
 
      Get a property from the Test.  The value of the property is stored in
      the variable VAR.  If the property is not found, VAR will be set to
      "NOTFOUND".  For a list of standard properties you can type cmake
      --help-property-list
 
      See also the more general get_property() command.
 
  if
      Conditionally execute a group of commands.
 
        if(expression)
          # then section.
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        elseif(expression2)
          # elseif section.
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        else(expression)
          # else section.
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        endif(expression)
 
      Evaluates the given expression.  If the result is true, the commands
      in the THEN section are invoked.  Otherwise, the commands in the else
      section are invoked.  The elseif and else sections are optional.  You
      may have multiple elseif clauses.  Note that the expression in the
      else and endif clause is optional.  Long expressions can be used and
      there is a traditional order of precedence.  Parenthetical expressions
      are evaluated first followed by unary operators such as EXISTS,
      COMMAND, and DEFINED.  Then any EQUAL, LESS, GREATER, STRLESS,
      STRGREATER, STREQUAL, MATCHES will be evaluated.  Then NOT operators
      and finally AND, OR operators will be evaluated.  Possible expressions
      are:
 
        if(<constant>)
 
      True if the constant is 1, ON, YES, TRUE, Y, or a non-zero number.
      False if the constant is 0, OFF, NO, FALSE, N, IGNORE, NOTFOUND, '',
      or ends in the suffix '-NOTFOUND'.  Named boolean constants are
      case-insensitive.  If the argument is not one of these constants, it
      is treated as a variable:
 
        if(<variable>)
 
      True if the variable is defined to a value that is not a false
      constant.  False otherwise.  (Note macro arguments are not variables.)
 
        if(NOT <expression>)
 
      True if the expression is not true.
 
        if(<expr1> AND <expr2>)
 
      True if both expressions would be considered true individually.
 
        if(<expr1> OR <expr2>)
 
      True if either expression would be considered true individually.
 
        if(COMMAND command-name)
 
      True if the given name is a command, macro or function that can be
      invoked.
 
        if(POLICY policy-id)
 
      True if the given name is an existing policy (of the form CMP<NNNN>).
 
        if(TARGET target-name)
 
      True if the given name is an existing target, built or imported.
 
        if(EXISTS file-name)
        if(EXISTS directory-name)
 
      True if the named file or directory exists.  Behavior is well-defined
      only for full paths.
 
        if(file1 IS_NEWER_THAN file2)
 
      True if file1 is newer than file2 or if one of the two files doesn't
      exist.  Behavior is well-defined only for full paths.  If the file
      time stamps are exactly the same, an IS_NEWER_THAN comparison returns
      true, so that any dependent build operations will occur in the event
      of a tie.  This includes the case of passing the same file name for
      both file1 and file2.
 
        if(IS_DIRECTORY directory-name)
 
      True if the given name is a directory.  Behavior is well-defined only
      for full paths.
 
        if(IS_SYMLINK file-name)
 
      True if the given name is a symbolic link.  Behavior is well-defined
      only for full paths.
 
        if(IS_ABSOLUTE path)
 
      True if the given path is an absolute path.
 
        if(<variable|string> MATCHES regex)
 
      True if the given string or variable's value matches the given regular
      expression.
 
        if(<variable|string> LESS <variable|string>)
        if(<variable|string> GREATER <variable|string>)
        if(<variable|string> EQUAL <variable|string>)
 
      True if the given string or variable's value is a valid number and the
      inequality or equality is true.
 
        if(<variable|string> STRLESS <variable|string>)
        if(<variable|string> STRGREATER <variable|string>)
        if(<variable|string> STREQUAL <variable|string>)
 
      True if the given string or variable's value is lexicographically less
      (or greater, or equal) than the string or variable on the right.
 
        if(<variable|string> VERSION_LESS <variable|string>)
        if(<variable|string> VERSION_EQUAL <variable|string>)
        if(<variable|string> VERSION_GREATER <variable|string>)
 
      Component-wise integer version number comparison (version format is
      major[.minor[.patch[.tweak]]]).
 
        if(DEFINED <variable>)
 
      True if the given variable is defined.  It does not matter if the
      variable is true or false just if it has been set.
 
        if((expression) AND (expression OR (expression)))
 
      The expressions inside the parenthesis are evaluated first and then
      the remaining expression is evaluated as in the previous examples.
      Where there are nested parenthesis the innermost are evaluated as part
      of evaluating the expression that contains them.
 
      The if command was written very early in CMake's history, predating
      the ${} variable evaluation syntax, and for convenience evaluates
      variables named by its arguments as shown in the above signatures.
      Note that normal variable evaluation with ${} applies before the if
      command even receives the arguments.  Therefore code like
 
        set(var1 OFF)
        set(var2 "var1")
        if(${var2})
 
      appears to the if command as
 
        if(var1)
 
      and is evaluated according to the if(<variable>) case documented
      above.  The result is OFF which is false.  However, if we remove the
      ${} from the example then the command sees
 
        if(var2)
 
      which is true because var2 is defined to "var1" which is not a false
      constant.
 
      Automatic evaluation applies in the other cases whenever the
      above-documented signature accepts <variable|string>:
 
      1) The left hand argument to MATCHES is first checked to see if it is
      a defined variable, if so the variable's value is used, otherwise the
      original value is used.
 
      2) If the left hand argument to MATCHES is missing it returns false
      without error
 
      3) Both left and right hand arguments to LESS GREATER EQUAL are
      independently tested to see if they are defined variables, if so their
      defined values are used otherwise the original value is used.
 
      4) Both left and right hand arguments to STRLESS STREQUAL STRGREATER
      are independently tested to see if they are defined variables, if so
      their defined values are used otherwise the original value is used.
 
      5) Both left and right hand argumemnts to VERSION_LESS VERSION_EQUAL
      VERSION_GREATER are independently tested to see if they are defined
      variables, if so their defined values are used otherwise the original
      value is used.
 
      6) The right hand argument to NOT is tested to see if it is a boolean
      constant, if so the value is used, otherwise it is assumed to be a
      variable and it is dereferenced.
 
      7) The left and right hand arguments to AND OR are independently
      tested to see if they are boolean constants, if so they are used as
      such, otherwise they are assumed to be variables and are dereferenced.
 
 
 
  include
      Read CMake listfile code from the given file.
 
        include(<file|module> [OPTIONAL] [RESULT_VARIABLE <VAR>]
                              [NO_POLICY_SCOPE])
 
      Reads CMake listfile code from the given file.  Commands in the file
      are processed immediately as if they were written in place of the
      include command.  If OPTIONAL is present, then no error is raised if
      the file does not exist.  If RESULT_VARIABLE is given the variable
      will be set to the full filename which has been included or NOTFOUND
      if it failed.
 
      If a module is specified instead of a file, the file with name
      <modulename>.cmake is searched first in CMAKE_MODULE_PATH, then in the
      CMake module directory.  There is one exception to this: if the file
      which calls include() is located itself in the CMake module directory,
      then first the CMake module directory is searched and
      CMAKE_MODULE_PATH afterwards.  See also policy CMP0017.
 
      See the cmake_policy() command documentation for discussion of the
      NO_POLICY_SCOPE option.
 
  include_directories
      Add include directories to the build.
 
        include_directories([AFTER|BEFORE] [SYSTEM] dir1 dir2 ...)
 
      Add the given directories to those the compiler uses to search for
      include files.  These directories are added to the directory property
      INCLUDE_DIRECTORIES for the current CMakeLists file.  They are also
      added to the target property INCLUDE_DIRECTORIES for each target in
      the current CMakeLists file.  The target property values are the ones
      used by the generators.
 
      By default the directories are appended onto the current list of
      directories.  This default behavior can be changed by setting
      CMAKE_INCLUDE_DIRECTORIES_BEFORE to ON.  By using AFTER or BEFORE
      explicitly, you can select between appending and prepending,
      independent of the default.  If the SYSTEM option is given, the
      compiler will be told the directories are meant as system include
      directories on some platforms.
 
  include_external_msproject
      Include an external Microsoft project file in a workspace.
 
        include_external_msproject(projectname location
                                    [TYPE projectTypeGUID]
                                    [GUID projectGUID]
                                    [PLATFORM platformName]
                                    dep1 dep2 ...)
 
      Includes an external Microsoft project in the generated workspace
      file.  Currently does nothing on UNIX.  This will create a target
      named [projectname].  This can be used in the add_dependencies command
      to make things depend on the external project.
 
      TYPE, GUID and PLATFORM are optional parameters that allow one to
      specify the type of project, id (GUID) of the project and the name of
      the target platform.  This is useful for projects requiring values
      other than the default (e.g.  WIX projects).  These options are not
      supported by the Visual Studio 6 generator.
 
  include_regular_expression
      Set the regular expression used for dependency checking.
 
        include_regular_expression(regex_match [regex_complain])
 
      Set the regular expressions used in dependency checking.  Only files
      matching regex_match will be traced as dependencies.  Only files
      matching regex_complain will generate warnings if they cannot be found
      (standard header paths are not searched).  The defaults are:
 
        regex_match    = "^.*$" (match everything)
        regex_complain = "^$" (match empty string only)
 
  install
      Specify rules to run at install time.
 
      This command generates installation rules for a project.  Rules
      specified by calls to this command within a source directory are
      executed in order during installation.  The order across directories
      is not defined.
 
      There are multiple signatures for this command.  Some of them define
      installation properties for files and targets.  Properties common to
      multiple signatures are covered here but they are valid only for
      signatures that specify them.
 
      DESTINATION arguments specify the directory on disk to which a file
      will be installed.  If a full path (with a leading slash or drive
      letter) is given it is used directly.  If a relative path is given it
      is interpreted relative to the value of CMAKE_INSTALL_PREFIX.  The
      prefix can be relocated at install time using DESTDIR mechanism
      explained in the CMAKE_INSTALL_PREFIX variable documentation.
 
      PERMISSIONS arguments specify permissions for installed files.  Valid
      permissions are OWNER_READ, OWNER_WRITE, OWNER_EXECUTE, GROUP_READ,
      GROUP_WRITE, GROUP_EXECUTE, WORLD_READ, WORLD_WRITE, WORLD_EXECUTE,
      SETUID, and SETGID.  Permissions that do not make sense on certain
      platforms are ignored on those platforms.
 
      The CONFIGURATIONS argument specifies a list of build configurations
      for which the install rule applies (Debug, Release, etc.).
 
      The COMPONENT argument specifies an installation component name with
      which the install rule is associated, such as "runtime" or
      "development".  During component-specific installation only install
      rules associated with the given component name will be executed.
      During a full installation all components are installed.  If COMPONENT
      is not provided a default component "Unspecified" is created.  The
      default component name may be controlled with the
      CMAKE_INSTALL_DEFAULT_COMPONENT_NAME variable.
 
      The RENAME argument specifies a name for an installed file that may be
      different from the original file.  Renaming is allowed only when a
      single file is installed by the command.
 
      The OPTIONAL argument specifies that it is not an error if the file to
      be installed does not exist.
 
      The TARGETS signature:
 
        install(TARGETS targets... [EXPORT <export-name>]
                [[ARCHIVE|LIBRARY|RUNTIME|FRAMEWORK|BUNDLE|
                  PRIVATE_HEADER|PUBLIC_HEADER|RESOURCE]
                  [DESTINATION <dir>]
                  [PERMISSIONS permissions...]
                  [CONFIGURATIONS [Debug|Release|...]]
                  [COMPONENT <component>]
                  [OPTIONAL] [NAMELINK_ONLY|NAMELINK_SKIP]
                ] [...])
 
      The TARGETS form specifies rules for installing targets from a
      project.  There are five kinds of target files that may be installed:
      ARCHIVE, LIBRARY, RUNTIME, FRAMEWORK, and BUNDLE.  Executables are
      treated as RUNTIME targets, except that those marked with the
      MACOSX_BUNDLE property are treated as BUNDLE targets on OS X.  Static
      libraries are always treated as ARCHIVE targets.  Module libraries are
      always treated as LIBRARY targets.  For non-DLL platforms shared
      libraries are treated as LIBRARY targets, except that those marked
      with the FRAMEWORK property are treated as FRAMEWORK targets on OS X.
      For DLL platforms the DLL part of a shared library is treated as a
      RUNTIME target and the corresponding import library is treated as an
      ARCHIVE target.  All Windows-based systems including Cygwin are DLL
      platforms.  The ARCHIVE, LIBRARY, RUNTIME, and FRAMEWORK arguments
      change the type of target to which the subsequent properties apply.
      If none is given the installation properties apply to all target
      types.  If only one is given then only targets of that type will be
      installed (which can be used to install just a DLL or just an import
      library).
 
      The PRIVATE_HEADER, PUBLIC_HEADER, and RESOURCE arguments cause
      subsequent properties to be applied to installing a FRAMEWORK shared
      library target's associated files on non-Apple platforms.  Rules
      defined by these arguments are ignored on Apple platforms because the
      associated files are installed into the appropriate locations inside
      the framework folder.  See documentation of the PRIVATE_HEADER,
      PUBLIC_HEADER, and RESOURCE target properties for details.
 
      Either NAMELINK_ONLY or NAMELINK_SKIP may be specified as a LIBRARY
      option.  On some platforms a versioned shared library has a symbolic
      link such as
 
        lib<name>.so -> lib<name>.so.1
 
      where "lib<name>.so.1" is the soname of the library and "lib<name>.so"
      is a "namelink" allowing linkers to find the library when given
      "-l<name>".  The NAMELINK_ONLY option causes installation of only the
      namelink when a library target is installed.  The NAMELINK_SKIP option
      causes installation of library files other than the namelink when a
      library target is installed.  When neither option is given both
      portions are installed.  On platforms where versioned shared libraries
      do not have namelinks or when a library is not versioned the
      NAMELINK_SKIP option installs the library and the NAMELINK_ONLY option
      installs nothing.  See the VERSION and SOVERSION target properties for
      details on creating versioned shared libraries.
 
      One or more groups of properties may be specified in a single call to
      the TARGETS form of this command.  A target may be installed more than
      once to different locations.  Consider hypothetical targets "myExe",
      "mySharedLib", and "myStaticLib".  The code
 
          install(TARGETS myExe mySharedLib myStaticLib
                  RUNTIME DESTINATION bin
                  LIBRARY DESTINATION lib
                  ARCHIVE DESTINATION lib/static)
          install(TARGETS mySharedLib DESTINATION /some/full/path)
 
      will install myExe to <prefix>/bin and myStaticLib to
      <prefix>/lib/static.  On non-DLL platforms mySharedLib will be
      installed to <prefix>/lib and /some/full/path.  On DLL platforms the
      mySharedLib DLL will be installed to <prefix>/bin and /some/full/path
      and its import library will be installed to <prefix>/lib/static and
      /some/full/path.
 
      The EXPORT option associates the installed target files with an export
      called <export-name>.  It must appear before any RUNTIME, LIBRARY, or
      ARCHIVE options.  To actually install the export file itself, call
      install(EXPORT).  See documentation of the install(EXPORT ...)
      signature below for details.
 
      Installing a target with EXCLUDE_FROM_ALL set to true has undefined
      behavior.
 
      The FILES signature:
 
        install(FILES files... DESTINATION <dir>
                [PERMISSIONS permissions...]
                [CONFIGURATIONS [Debug|Release|...]]
                [COMPONENT <component>]
                [RENAME <name>] [OPTIONAL])
 
      The FILES form specifies rules for installing files for a project.
      File names given as relative paths are interpreted with respect to the
      current source directory.  Files installed by this form are by default
      given permissions OWNER_WRITE, OWNER_READ, GROUP_READ, and WORLD_READ
      if no PERMISSIONS argument is given.
 
      The PROGRAMS signature:
 
        install(PROGRAMS files... DESTINATION <dir>
                [PERMISSIONS permissions...]
                [CONFIGURATIONS [Debug|Release|...]]
                [COMPONENT <component>]
                [RENAME <name>] [OPTIONAL])
 
      The PROGRAMS form is identical to the FILES form except that the
      default permissions for the installed file also include OWNER_EXECUTE,
      GROUP_EXECUTE, and WORLD_EXECUTE.  This form is intended to install
      programs that are not targets, such as shell scripts.  Use the TARGETS
      form to install targets built within the project.
 
      The DIRECTORY signature:
 
        install(DIRECTORY dirs... DESTINATION <dir>
                [FILE_PERMISSIONS permissions...]
                [DIRECTORY_PERMISSIONS permissions...]
                [USE_SOURCE_PERMISSIONS] [OPTIONAL]
                [CONFIGURATIONS [Debug|Release|...]]
                [COMPONENT <component>] [FILES_MATCHING]
                [[PATTERN <pattern> | REGEX <regex>]
                  [EXCLUDE] [PERMISSIONS permissions...]] [...])
 
      The DIRECTORY form installs contents of one or more directories to a
      given destination.  The directory structure is copied verbatim to the
      destination.  The last component of each directory name is appended to
      the destination directory but a trailing slash may be used to avoid
      this because it leaves the last component empty.  Directory names
      given as relative paths are interpreted with respect to the current
      source directory.  If no input directory names are given the
      destination directory will be created but nothing will be installed
      into it.  The FILE_PERMISSIONS and DIRECTORY_PERMISSIONS options
      specify permissions given to files and directories in the destination.
      If USE_SOURCE_PERMISSIONS is specified and FILE_PERMISSIONS is not,
      file permissions will be copied from the source directory structure.
      If no permissions are specified files will be given the default
      permissions specified in the FILES form of the command, and the
      directories will be given the default permissions specified in the
      PROGRAMS form of the command.
 
      Installation of directories may be controlled with fine granularity
      using the PATTERN or REGEX options.  These "match" options specify a
      globbing pattern or regular expression to match directories or files
      encountered within input directories.  They may be used to apply
      certain options (see below) to a subset of the files and directories
      encountered.  The full path to each input file or directory (with
      forward slashes) is matched against the expression.  A PATTERN will
      match only complete file names: the portion of the full path matching
      the pattern must occur at the end of the file name and be preceded by
      a slash.  A REGEX will match any portion of the full path but it may
      use '/' and '$' to simulate the PATTERN behavior.  By default all
      files and directories are installed whether or not they are matched.
      The FILES_MATCHING option may be given before the first match option
      to disable installation of files (but not directories) not matched by
      any expression.  For example, the code
 
        install(DIRECTORY src/ DESTINATION include/myproj
                FILES_MATCHING PATTERN "*.h")
 
      will extract and install header files from a source tree.
 
      Some options may follow a PATTERN or REGEX expression and are applied
      only to files or directories matching them.  The EXCLUDE option will
      skip the matched file or directory.  The PERMISSIONS option overrides
      the permissions setting for the matched file or directory.  For
      example the code
 
        install(DIRECTORY icons scripts/ DESTINATION share/myproj
                PATTERN "CVS" EXCLUDE
                PATTERN "scripts/*"
                PERMISSIONS OWNER_EXECUTE OWNER_WRITE OWNER_READ
                            GROUP_EXECUTE GROUP_READ)
 
      will install the icons directory to share/myproj/icons and the scripts
      directory to share/myproj.  The icons will get default file
      permissions, the scripts will be given specific permissions, and any
      CVS directories will be excluded.
 
      The SCRIPT and CODE signature:
 
        install([[SCRIPT <file>] [CODE <code>]] [...])
 
      The SCRIPT form will invoke the given CMake script files during
      installation.  If the script file name is a relative path it will be
      interpreted with respect to the current source directory.  The CODE
      form will invoke the given CMake code during installation.  Code is
      specified as a single argument inside a double-quoted string.  For
      example, the code
 
        install(CODE "MESSAGE(\"Sample install message.\")")
 
      will print a message during installation.
 
      The EXPORT signature:
 
        install(EXPORT <export-name> DESTINATION <dir>
                [NAMESPACE <namespace>] [FILE <name>.cmake]
                [PERMISSIONS permissions...]
                [CONFIGURATIONS [Debug|Release|...]]
                [COMPONENT <component>])
 
      The EXPORT form generates and installs a CMake file containing code to
      import targets from the installation tree into another project.
      Target installations are associated with the export <export-name>
      using the EXPORT option of the install(TARGETS ...) signature
      documented above.  The NAMESPACE option will prepend <namespace> to
      the target names as they are written to the import file.  By default
      the generated file will be called <export-name>.cmake but the FILE
      option may be used to specify a different name.  The value given to
      the FILE option must be a file name with the ".cmake" extension.  If a
      CONFIGURATIONS option is given then the file will only be installed
      when one of the named configurations is installed.  Additionally, the
      generated import file will reference only the matching target
      configurations.  If a COMPONENT option is specified that does not
      match that given to the targets associated with <export-name> the
      behavior is undefined.  If a library target is included in the export
      but a target to which it links is not included the behavior is
      unspecified.
 
      The EXPORT form is useful to help outside projects use targets built
      and installed by the current project.  For example, the code
 
        install(TARGETS myexe EXPORT myproj DESTINATION bin)
        install(EXPORT myproj NAMESPACE mp_ DESTINATION lib/myproj)
 
      will install the executable myexe to <prefix>/bin and code to import
      it in the file "<prefix>/lib/myproj/myproj.cmake".  An outside project
      may load this file with the include command and reference the myexe
      executable from the installation tree using the imported target name
      mp_myexe as if the target were built in its own tree.
 
      NOTE: This command supercedes the INSTALL_TARGETS command and the
      target properties PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT.  It also
      replaces the FILES forms of the INSTALL_FILES and INSTALL_PROGRAMS
      commands.  The processing order of these install rules relative to
      those generated by INSTALL_TARGETS, INSTALL_FILES, and
      INSTALL_PROGRAMS commands is not defined.
 
 
  link_directories
      Specify directories in which the linker will look for libraries.
 
        link_directories(directory1 directory2 ...)
 
      Specify the paths in which the linker should search for libraries.
      The command will apply only to targets created after it is called.
      For historical reasons, relative paths given to this command are
      passed to the linker unchanged (unlike many CMake commands which
      interpret them relative to the current source directory).
 
      Note that this command is rarely necessary.  Library locations
      returned by find_package() and find_library() are absolute paths.
      Pass these absolute library file paths directly to the
      target_link_libraries() command.  CMake will ensure the linker finds
      them.
 
  list
      List operations.
 
        list(LENGTH <list> <output variable>)
        list(GET <list> <element index> [<element index> ...]
              <output variable>)
        list(APPEND <list> <element> [<element> ...])
        list(FIND <list> <value> <output variable>)
        list(INSERT <list> <element_index> <element> [<element> ...])
        list(REMOVE_ITEM <list> <value> [<value> ...])
        list(REMOVE_AT <list> <index> [<index> ...])
        list(REMOVE_DUPLICATES <list>)
        list(REVERSE <list>)
        list(SORT <list>)
 
      LENGTH will return a given list's length.
 
      GET will return list of elements specified by indices from the list.
 
      APPEND will append elements to the list.
 
      FIND will return the index of the element specified in the list or -1
      if it wasn't found.
 
      INSERT will insert elements to the list to the specified location.
 
      REMOVE_AT and REMOVE_ITEM will remove items from the list.  The
      difference is that REMOVE_ITEM will remove the given items, while
      REMOVE_AT will remove the items at the given indices.
 
      REMOVE_DUPLICATES will remove duplicated items in the list.
 
      REVERSE reverses the contents of the list in-place.
 
      SORT sorts the list in-place alphabetically.
 
      The list subcommands APPEND, INSERT, REMOVE_AT, REMOVE_ITEM,
      REMOVE_DUPLICATES, REVERSE and SORT may create new values for the list
      within the current CMake variable scope.  Similar to the SET command,
      the LIST command creates new variable values in the current scope,
      even if the list itself is actually defined in a parent scope.  To
      propagate the results of these operations upwards, use SET with
      PARENT_SCOPE, SET with CACHE INTERNAL, or some other means of value
      propagation.
 
      NOTES: A list in cmake is a ; separated group of strings.  To create a
      list the set command can be used.  For example, set(var a b c d e)
      creates a list with a;b;c;d;e, and set(var "a b c d e") creates a
      string or a list with one item in it.
 
      When specifying index values, if <element index> is 0 or greater, it
      is indexed from the beginning of the list, with 0 representing the
      first list element.  If <element index> is -1 or lesser, it is indexed
      from the end of the list, with -1 representing the last list element.
      Be careful when counting with negative indices: they do not start from
      0.  -0 is equivalent to 0, the first list element.
 
 
  load_cache
      Load in the values from another project's CMake cache.
 
        load_cache(pathToCacheFile READ_WITH_PREFIX
                    prefix entry1...)
 
      Read the cache and store the requested entries in variables with their
      name prefixed with the given prefix.  This only reads the values, and
      does not create entries in the local project's cache.
 
        load_cache(pathToCacheFile [EXCLUDE entry1...]
                    [INCLUDE_INTERNALS entry1...])
 
      Load in the values from another cache and store them in the local
      project's cache as internal entries.  This is useful for a project
      that depends on another project built in a different tree.  EXCLUDE
      option can be used to provide a list of entries to be excluded.
      INCLUDE_INTERNALS can be used to provide a list of internal entries to
      be included.  Normally, no internal entries are brought in.  Use of
      this form of the command is strongly discouraged, but it is provided
      for backward compatibility.
 
  load_command
      Load a command into a running CMake.
 
        load_command(COMMAND_NAME <loc1> [loc2 ...])
 
      The given locations are searched for a library whose name is
      cmCOMMAND_NAME.  If found, it is loaded as a module and the command is
      added to the set of available CMake commands.  Usually, TRY_COMPILE is
      used before this command to compile the module.  If the command is
      successfully loaded a variable named
 
        CMAKE_LOADED_COMMAND_<COMMAND_NAME>
 
      will be set to the full path of the module that was loaded.  Otherwise
      the variable will not be set.
 
  macro
      Start recording a macro for later invocation as a command.
 
        macro(<name> [arg1 [arg2 [arg3 ...]]])
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        endmacro(<name>)
 
      Define a macro named <name> that takes arguments named arg1 arg2 arg3
      (...).  Commands listed after macro, but before the matching endmacro,
      are not invoked until the macro is invoked.  When it is invoked, the
      commands recorded in the macro are first modified by replacing formal
      parameters (${arg1}) with the arguments passed, and then invoked as
      normal commands.  In addition to referencing the formal parameters you
      can reference the values ${ARGC} which will be set to the number of
      arguments passed into the function as well as ${ARGV0} ${ARGV1}
      ${ARGV2} ...  which will have the actual values of the arguments
      passed in.  This facilitates creating macros with optional arguments.
      Additionally ${ARGV} holds the list of all arguments given to the
      macro and ${ARGN} holds the list of argument past the last expected
      argument.  Note that the parameters to a macro and values such as ARGN
      are not variables in the usual CMake sense.  They are string
      replacements much like the c preprocessor would do with a macro.  If
      you want true CMake variables you should look at the function command.
 
      See the cmake_policy() command documentation for the behavior of
      policies inside macros.
 
  mark_as_advanced
      Mark cmake cached variables as advanced.
 
        mark_as_advanced([CLEAR|FORCE] VAR VAR2 VAR...)
 
      Mark the named cached variables as advanced.  An advanced variable
      will not be displayed in any of the cmake GUIs unless the show
      advanced option is on.  If CLEAR is the first argument advanced
      variables are changed back to unadvanced.  If FORCE is the first
      argument, then the variable is made advanced.  If neither FORCE nor
      CLEAR is specified, new values will be marked as advanced, but if the
      variable already has an advanced/non-advanced state, it will not be
      changed.
 
      It does nothing in script mode.
 
  math
      Mathematical expressions.
 
        math(EXPR <output variable> <math expression>)
 
      EXPR evaluates mathematical expression and return result in the output
      variable.  Example mathematical expression is '5 * ( 10 + 13 )'.
      Supported operators are + - * / % | & ^ ~ << >> * / %.  They have the
      same meaning as they do in c code.
 
  message
      Display a message to the user.
 
        message([STATUS|WARNING|AUTHOR_WARNING|FATAL_ERROR|SEND_ERROR]
                "message to display" ...)
 
      The optional keyword determines the type of message:
 
        (none)        = Important information
        STATUS        = Incidental information
        WARNING        = CMake Warning, continue processing
        AUTHOR_WARNING = CMake Warning (dev), continue processing
        SEND_ERROR    = CMake Error, continue but skip generation
        FATAL_ERROR    = CMake Error, stop all processing
 
      The CMake command-line tool displays STATUS messages on stdout and all
      other message types on stderr.  The CMake GUI displays all messages in
      its log area.  The interactive dialogs (ccmake and CMakeSetup) show
      STATUS messages one at a time on a status line and other messages in
      interactive pop-up boxes.
 
      CMake Warning and Error message text displays using a simple markup
      language.  Non-indented text is formatted in line-wrapped paragraphs
      delimited by newlines.  Indented text is considered pre-formatted.
 
  option
      Provides an option that the user can optionally select.
 
        option(<option_variable> "help string describing option"
                [initial value])
 
      Provide an option for the user to select as ON or OFF.  If no initial
      value is provided, OFF is used.
 
      If you have options that depend on the values of other options, see
      the module help for CMakeDependentOption.
 
  project
      Set a name for the entire project.
 
        project(<projectname> [languageName1 languageName2 ... ] )
 
      Sets the name of the project.  Additionally this sets the variables
      <projectName>_BINARY_DIR and <projectName>_SOURCE_DIR to the
      respective values.
 
      Optionally you can specify which languages your project supports.
      Example languages are CXX (i.e.  C++), C, Fortran, etc.  By default C
      and CXX are enabled.  E.g.  if you do not have a C++ compiler, you can
      disable the check for it by explicitly listing the languages you want
      to support, e.g.  C.  By using the special language "NONE" all checks
      for any language can be disabled.  If a variable exists called
      CMAKE_PROJECT_<projectName>_INCLUDE, the file pointed to by that
      variable will be included as the last step of the project command.
 
  qt_wrap_cpp
      Create Qt Wrappers.
 
        qt_wrap_cpp(resultingLibraryName DestName
                    SourceLists ...)
 
      Produce moc files for all the .h files listed in the SourceLists.  The
      moc files will be added to the library using the DestName source list.
 
  qt_wrap_ui
      Create Qt user interfaces Wrappers.
 
        qt_wrap_ui(resultingLibraryName HeadersDestName
                    SourcesDestName SourceLists ...)
 
      Produce .h and .cxx files for all the .ui files listed in the
      SourceLists.  The .h files will be added to the library using the
      HeadersDestNamesource list.  The .cxx files will be added to the
      library using the SourcesDestNamesource list.
 
  remove_definitions
      Removes -D define flags added by add_definitions.
 
        remove_definitions(-DFOO -DBAR ...)
 
      Removes flags (added by add_definitions) from the compiler command
      line for sources in the current directory and below.
 
  return
      Return from a file, directory or function.
 
        return()
 
      Returns from a file, directory or function.  When this command is
      encountered in an included file (via include() or find_package()), it
      causes processing of the current file to stop and control is returned
      to the including file.  If it is encountered in a file which is not
      included by another file, e.g.  a CMakeLists.txt, control is returned
      to the parent directory if there is one.  If return is called in a
      function, control is returned to the caller of the function.  Note
      that a macro is not a function and does not handle return like a
      function does.
 
  separate_arguments
      Parse space-separated arguments into a semicolon-separated list.
 
        separate_arguments(<var> <UNIX|WINDOWS>_COMMAND "<args>")
 
      Parses a unix- or windows-style command-line string "<args>" and
      stores a semicolon-separated list of the arguments in <var>.  The
      entire command line must be given in one "<args>" argument.
 
      The UNIX_COMMAND mode separates arguments by unquoted whitespace.  It
      recognizes both single-quote and double-quote pairs.  A backslash
      escapes the next literal character (\" is "); there are no special
      escapes (\n is just n).
 
      The WINDOWS_COMMAND mode parses a windows command-line using the same
      syntax the runtime library uses to construct argv at startup.  It
      separates arguments by whitespace that is not double-quoted.
      Backslashes are literal unless they precede double-quotes.  See the
      MSDN article "Parsing C Command-Line Arguments" for details.
 
        separate_arguments(VARIABLE)
 
      Convert the value of VARIABLE to a semi-colon separated list.  All
      spaces are replaced with ';'.  This helps with generating command
      lines.
 
  set
      Set a CMake, cache or environment variable to a given value.
 
        set(<variable> <value>
            [[CACHE <type> <docstring> [FORCE]] | PARENT_SCOPE])
 
      Within CMake sets <variable> to the value <value>.  <value> is
      expanded before <variable> is set to it.  Normally, set will set a
      regular CMake variable.  If CACHE is present, then the <variable> is
      put in the cache instead, unless it is already in the cache.  See
      section 'Variable types in CMake' below for details of regular and
      cache variables and their interactions.  If CACHE is used, <type> and
      <docstring> are required.  <type> is used by the CMake GUI to choose a
      widget with which the user sets a value.  The value for <type> may be
      one of
 
        FILEPATH = File chooser dialog.
        PATH    = Directory chooser dialog.
        STRING  = Arbitrary string.
        BOOL    = Boolean ON/OFF checkbox.
        INTERNAL = No GUI entry (used for persistent variables).
 
      If <type> is INTERNAL, the cache variable is marked as internal, and
      will not be shown to the user in tools like cmake-gui.  This is
      intended for values that should be persisted in the cache, but which
      users should not normally change.  INTERNAL implies FORCE.
 
      Normally, set(...CACHE...) creates cache variables, but does not
      modify them.  If FORCE is specified, the value of the cache variable
      is set, even if the variable is already in the cache.  This should
      normally be avoided, as it will remove any changes to the cache
      variable's value by the user.
 
      If PARENT_SCOPE is present, the variable will be set in the scope
      above the current scope.  Each new directory or function creates a new
      scope.  This command will set the value of a variable into the parent
      directory or calling function (whichever is applicable to the case at
      hand).  PARENT_SCOPE cannot be combined with CACHE.
 
      If <value> is not specified then the variable is removed instead of
      set.  See also: the unset() command.
 
        set(<variable> <value1> ... <valueN>)
 
      In this case <variable> is set to a semicolon separated list of
      values.
 
      <variable> can be an environment variable such as:
 
        set( ENV{PATH} /home/martink )
 
      in which case the environment variable will be set.
 
      *** Variable types in CMake ***
 
      In CMake there are two types of variables: normal variables and cache
      variables.  Normal variables are meant for the internal use of the
      script (just like variables in most programming languages); they are
      not persisted across CMake runs.  Cache variables (unless set with
      INTERNAL) are mostly intended for configuration settings where the
      first CMake run determines a suitable default value, which the user
      can then override, by editing the cache with tools such as ccmake or
      cmake-gui.  Cache variables are stored in the CMake cache file, and
      are persisted across CMake runs.
 
      Both types can exist at the same time with the same name but different
      values.  When ${FOO} is evaluated, CMake first looks for a normal
      variable 'FOO' in scope and uses it if set.  If and only if no normal
      variable exists then it falls back to the cache variable 'FOO'.
 
      Some examples:
 
      The code 'set(FOO "x")' sets the normal variable 'FOO'.  It does not
      touch the cache, but it will hide any existing cache value 'FOO'.
 
      The code 'set(FOO "x" CACHE ...)' checks for 'FOO' in the cache,
      ignoring any normal variable of the same name.  If 'FOO' is in the
      cache then nothing happens to either the normal variable or the cache
      variable.  If 'FOO' is not in the cache, then it is added to the
      cache.
 
      Finally, whenever a cache variable is added or modified by a command,
      CMake also *removes* the normal variable of the same name from the
      current scope so that an immediately following evaluation of it will
      expose the newly cached value.
 
      Normally projects should avoid using normal and cache variables of the
      same name, as this interaction can be hard to follow.  However, in
      some situations it can be useful.  One example (used by some
      projects):
 
      A project has a subproject in its source tree.  The child project has
      its own CMakeLists.txt, which is included from the parent
      CMakeLists.txt using add_subdirectory().  Now, if the parent and the
      child project provide the same option (for example a compiler option),
      the parent gets the first chance to add a user-editable option to the
      cache.  Normally, the child would then use the same value that the
      parent uses.  However, it may be necessary to hard-code the value for
      the child project's option while still allowing the user to edit the
      value used by the parent project.  The parent project can achieve this
      simply by setting a normal variable with the same name as the option
      in a scope sufficient to hide the option's cache variable from the
      child completely.  The parent has already set the cache variable, so
      the child's set(...CACHE...) will do nothing, and evaluating the
      option variable will use the value from the normal variable, which
      hides the cache variable.
 
  set_directory_properties
      Set a property of the directory.
 
        set_directory_properties(PROPERTIES prop1 value1 prop2 value2)
 
      Set a property for the current directory and subdirectories.  If the
      property is not found, CMake will report an error.  The properties
      include: INCLUDE_DIRECTORIES, LINK_DIRECTORIES,
      INCLUDE_REGULAR_EXPRESSION, and ADDITIONAL_MAKE_CLEAN_FILES.
      ADDITIONAL_MAKE_CLEAN_FILES is a list of files that will be cleaned as
      a part of "make clean" stage.
 
  set_property
      Set a named property in a given scope.
 
        set_property(<GLOBAL                            |
                      DIRECTORY [dir]                  |
                      TARGET    [target1 [target2 ...]] |
                      SOURCE    [src1 [src2 ...]]      |
                      TEST      [test1 [test2 ...]]    |
                      CACHE    [entry1 [entry2 ...]]>
                      [APPEND] [APPEND_STRING]
                      PROPERTY <name> [value1 [value2 ...]])
 
      Set one property on zero or more objects of a scope.  The first
      argument determines the scope in which the property is set.  It must
      be one of the following:
 
      GLOBAL scope is unique and does not accept a name.
 
      DIRECTORY scope defaults to the current directory but another
      directory (already processed by CMake) may be named by full or
      relative path.
 
      TARGET scope may name zero or more existing targets.
 
      SOURCE scope may name zero or more source files.  Note that source
      file properties are visible only to targets added in the same
      directory (CMakeLists.txt).
 
      TEST scope may name zero or more existing tests.
 
      CACHE scope must name zero or more cache existing entries.
 
      The required PROPERTY option is immediately followed by the name of
      the property to set.  Remaining arguments are used to compose the
      property value in the form of a semicolon-separated list.  If the
      APPEND option is given the list is appended to any existing property
      value.If the APPEND_STRING option is given the string is append to any
      existing property value as string, i.e.  it results in a longer string
      and not a list of strings.
 
  set_source_files_properties
      Source files can have properties that affect how they are built.
 
        set_source_files_properties([file1 [file2 [...]]]
                                    PROPERTIES prop1 value1
                                    [prop2 value2 [...]])
 
      Set properties associated with source files using a key/value paired
      list.  See properties documentation for those known to CMake.
      Unrecognized properties are ignored.  Source file properties are
      visible only to targets added in the same directory (CMakeLists.txt).
 
  set_target_properties
      Targets can have properties that affect how they are built.
 
        set_target_properties(target1 target2 ...
                              PROPERTIES prop1 value1
                              prop2 value2 ...)
 
      Set properties on a target.  The syntax for the command is to list all
      the files you want to change, and then provide the values you want to
      set next.  You can use any prop value pair you want and extract it
      later with the GET_TARGET_PROPERTY command.
 
      Properties that affect the name of a target's output file are as
      follows.  The PREFIX and SUFFIX properties override the default target
      name prefix (such as "lib") and suffix (such as ".so").  IMPORT_PREFIX
      and IMPORT_SUFFIX are the equivalent properties for the import library
      corresponding to a DLL (for SHARED library targets).  OUTPUT_NAME sets
      the real name of a target when it is built and can be used to help
      create two targets of the same name even though CMake requires unique
      logical target names.  There is also a <CONFIG>_OUTPUT_NAME that can
      set the output name on a per-configuration basis.  <CONFIG>_POSTFIX
      sets a postfix for the real name of the target when it is built under
      the configuration named by <CONFIG> (in upper-case, such as
      "DEBUG_POSTFIX").  The value of this property is initialized when the
      target is created to the value of the variable CMAKE_<CONFIG>_POSTFIX
      (except for executable targets because earlier CMake versions which
      did not use this variable for executables).
 
      The LINK_FLAGS property can be used to add extra flags to the link
      step of a target.  LINK_FLAGS_<CONFIG> will add to the configuration
      <CONFIG>, for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO.
      DEFINE_SYMBOL sets the name of the preprocessor symbol defined when
      compiling sources in a shared library.  If not set here then it is set
      to target_EXPORTS by default (with some substitutions if the target is
      not a valid C identifier).  This is useful for headers to know whether
      they are being included from inside their library or outside to
      properly setup dllexport/dllimport decorations.  The COMPILE_FLAGS
      property sets additional compiler flags used to build sources within
      the target.  It may also be used to pass additional preprocessor
      definitions.
 
      The LINKER_LANGUAGE property is used to change the tool used to link
      an executable or shared library.  The default is set the language to
      match the files in the library.  CXX and C are common values for this
      property.
 
      For shared libraries VERSION and SOVERSION can be used to specify the
      build version and api version respectively.  When building or
      installing appropriate symlinks are created if the platform supports
      symlinks and the linker supports so-names.  If only one of both is
      specified the missing is assumed to have the same version number.  For
      executables VERSION can be used to specify the build version.  When
      building or installing appropriate symlinks are created if the
      platform supports symlinks.  For shared libraries and executables on
      Windows the VERSION attribute is parsed to extract a "major.minor"
      version number.  These numbers are used as the image version of the
      binary.
 
      There are a few properties used to specify RPATH rules.  INSTALL_RPATH
      is a semicolon-separated list specifying the rpath to use in installed
      targets (for platforms that support it).  INSTALL_RPATH_USE_LINK_PATH
      is a boolean that if set to true will append directories in the linker
      search path and outside the project to the INSTALL_RPATH.
      SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic
      generation of an rpath allowing the target to run from the build tree.
      BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the
      target in the build tree with the INSTALL_RPATH.  This takes
      precedence over SKIP_BUILD_RPATH and avoids the need for relinking
      before installation.  INSTALL_NAME_DIR is a string specifying the
      directory portion of the "install_name" field of shared libraries on
      Mac OSX to use in the installed targets.  When the target is created
      the values of the variables CMAKE_INSTALL_RPATH,
      CMAKE_INSTALL_RPATH_USE_LINK_PATH, CMAKE_SKIP_BUILD_RPATH,
      CMAKE_BUILD_WITH_INSTALL_RPATH, and CMAKE_INSTALL_NAME_DIR are used to
      initialize these properties.
 
      PROJECT_LABEL can be used to change the name of the target in an IDE
      like visual studio.  VS_KEYWORD can be set to change the visual studio
      keyword, for example Qt integration works better if this is set to
      Qt4VSv1.0.
 
      VS_SCC_PROJECTNAME, VS_SCC_LOCALPATH, VS_SCC_PROVIDER and
      VS_SCC_AUXPATH can be set to add support for source control bindings
      in a Visual Studio project file.
 
      VS_GLOBAL_<variable> can be set to add a Visual Studio
      project-specific global variable.  Qt integration works better if
      VS_GLOBAL_QtVersion is set to the Qt version FindQt4.cmake found.  For
      example, "4.7.3"
 
      The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
      way to specify CMake scripts to run before and after installing a
      target.  They are used only when the old INSTALL_TARGETS command is
      used to install the target.  Use the INSTALL command instead.
 
      The EXCLUDE_FROM_DEFAULT_BUILD property is used by the visual studio
      generators.  If it is set to 1 the target will not be part of the
      default build when you select "Build Solution".
 
  set_tests_properties
      Set a property of the tests.
 
        set_tests_properties(test1 [test2...] PROPERTIES prop1 value1 prop2 value2)
 
      Set a property for the tests.  If the property is not found, CMake
      will report an error.  The properties include:
 
      WILL_FAIL: If set to true, this will invert the pass/fail flag of the
      test.
 
      PASS_REGULAR_EXPRESSION: If set, the test output will be checked
      against the specified regular expressions and at least one of the
      regular expressions has to match, otherwise the test will fail.
 
        Example: PASS_REGULAR_EXPRESSION "TestPassed;All ok"
 
      FAIL_REGULAR_EXPRESSION: If set, if the output will match to one of
      specified regular expressions, the test will fail.
 
        Example: PASS_REGULAR_EXPRESSION "[^a-z]Error;ERROR;Failed"
 
      Both PASS_REGULAR_EXPRESSION and FAIL_REGULAR_EXPRESSION expect a list
      of regular expressions.
 
      TIMEOUT: Setting this will limit the test runtime to the number of
      seconds specified.
 
 
  site_name
      Set the given variable to the name of the computer.
 
        site_name(variable)
 
 
  source_group
      Define a grouping for sources in the makefile.
 
        source_group(name [REGULAR_EXPRESSION regex] [FILES src1 src2 ...])
 
      Defines a group into which sources will be placed in project files.
      This is mainly used to setup file tabs in Visual Studio.  Any file
      whose name is listed or matches the regular expression will be placed
      in this group.  If a file matches multiple groups, the LAST group that
      explicitly lists the file will be favored, if any.  If no group
      explicitly lists the file, the LAST group whose regular expression
      matches the file will be favored.
 
      The name of the group may contain backslashes to specify subgroups:
 
        source_group(outer\\inner ...)
 
      For backwards compatibility, this command is also supports the format:
 
        source_group(name regex)
 
  string
      String operations.
 
        string(REGEX MATCH <regular_expression>
                <output variable> <input> [<input>...])
        string(REGEX MATCHALL <regular_expression>
                <output variable> <input> [<input>...])
        string(REGEX REPLACE <regular_expression>
                <replace_expression> <output variable>
                <input> [<input>...])
        string(REPLACE <match_string>
                <replace_string> <output variable>
                <input> [<input>...])
        string(<MD5|SHA1|SHA224|SHA256|SHA384|SHA512>
                <output variable> <input>)
        string(COMPARE EQUAL <string1> <string2> <output variable>)
        string(COMPARE NOTEQUAL <string1> <string2> <output variable>)
        string(COMPARE LESS <string1> <string2> <output variable>)
        string(COMPARE GREATER <string1> <string2> <output variable>)
        string(ASCII <number> [<number> ...] <output variable>)
        string(CONFIGURE <string1> <output variable>
                [@ONLY] [ESCAPE_QUOTES])
        string(TOUPPER <string1> <output variable>)
        string(TOLOWER <string1> <output variable>)
        string(LENGTH <string> <output variable>)
        string(SUBSTRING <string> <begin> <length> <output variable>)
        string(STRIP <string> <output variable>)
        string(RANDOM [LENGTH <length>] [ALPHABET <alphabet>]
                [RANDOM_SEED <seed>] <output variable>)
        string(FIND <string> <substring> <output variable> [REVERSE])
 
      REGEX MATCH will match the regular expression once and store the match
      in the output variable.
 
      REGEX MATCHALL will match the regular expression as many times as
      possible and store the matches in the output variable as a list.
 
      REGEX REPLACE will match the regular expression as many times as
      possible and substitute the replacement expression for the match in
      the output.  The replace expression may refer to paren-delimited
      subexpressions of the match using \1, \2, ..., \9.  Note that two
      backslashes (\\1) are required in CMake code to get a backslash
      through argument parsing.
 
      REPLACE will replace all occurrences of match_string in the input with
      replace_string and store the result in the output.
 
      MD5, SHA1, SHA224, SHA256, SHA384, and SHA512 will compute a
      cryptographic hash of the input string.
 
      COMPARE EQUAL/NOTEQUAL/LESS/GREATER will compare the strings and store
      true or false in the output variable.
 
      ASCII will convert all numbers into corresponding ASCII characters.
 
      CONFIGURE will transform a string like CONFIGURE_FILE transforms a
      file.
 
      TOUPPER/TOLOWER will convert string to upper/lower characters.
 
      LENGTH will return a given string's length.
 
      SUBSTRING will return a substring of a given string.  If length is -1
      the remainder of the string starting at begin will be returned.
 
      STRIP will return a substring of a given string with leading and
      trailing spaces removed.
 
      RANDOM will return a random string of given length consisting of
      characters from the given alphabet.  Default length is 5 characters
      and default alphabet is all numbers and upper and lower case letters.
      If an integer RANDOM_SEED is given, its value will be used to seed the
      random number generator.
 
      FIND will return the position where the given substring was found in
      the supplied string.  If the REVERSE flag was used, the command will
      search for the position of the last occurrence of the specified
      substring.
 
      The following characters have special meaning in regular expressions:
 
          ^        Matches at beginning of a line
          $        Matches at end of a line
          .        Matches any single character
          [ ]      Matches any character(s) inside the brackets
          [^ ]      Matches any character(s) not inside the brackets
          -        Inside brackets, specifies an inclusive range between
                    characters on either side e.g. [a-f] is [abcdef]
          *        Matches preceding pattern zero or more times
          +        Matches preceding pattern one or more times
          ?        Matches preceding pattern zero or once only
          |        Matches a pattern on either side of the |
          ()        Saves a matched subexpression, which can be referenced
                    in the REGEX REPLACE operation. Additionally it is saved
                    by all regular expression-related commands, including
                    e.g. if( MATCHES ), in the variables CMAKE_MATCH_(0..9).
 
  target_link_libraries
      Link a target to given libraries.
 
        target_link_libraries(<target> [item1 [item2 [...]]]
                              [[debug|optimized|general] <item>] ...)
 
      Specify libraries or flags to use when linking a given target.  The
      named <target> must have been created in the current directory by a
      command such as add_executable or add_library.  The remaining
      arguments specify library names or flags.  Repeated calls for the same
      <target> append items in the order called.
 
      If a library name matches that of another target in the project a
      dependency will automatically be added in the build system to make
      sure the library being linked is up-to-date before the target links.
      Item names starting with '-', but not '-l' or '-framework', are
      treated as linker flags.
 
      A "debug", "optimized", or "general" keyword indicates that the
      library immediately following it is to be used only for the
      corresponding build configuration.  The "debug" keyword corresponds to
      the Debug configuration (or to configurations named in the
      DEBUG_CONFIGURATIONS global property if it is set).  The "optimized"
      keyword corresponds to all other configurations.  The "general"
      keyword corresponds to all configurations, and is purely optional
      (assumed if omitted).  Higher granularity may be achieved for
      per-configuration rules by creating and linking to IMPORTED library
      targets.  See the IMPORTED mode of the add_library command for more
      information.
 
      Library dependencies are transitive by default.  When this target is
      linked into another target then the libraries linked to this target
      will appear on the link line for the other target too.  See the
      LINK_INTERFACE_LIBRARIES target property to override the set of
      transitive link dependencies for a target.
 
        target_link_libraries(<target> LINK_INTERFACE_LIBRARIES
                              [[debug|optimized|general] <lib>] ...)
 
      The LINK_INTERFACE_LIBRARIES mode appends the libraries to the
      LINK_INTERFACE_LIBRARIES and its per-configuration equivalent target
      properties instead of using them for linking.  Libraries specified as
      "debug" are appended to the the LINK_INTERFACE_LIBRARIES_DEBUG
      property (or to the properties corresponding to configurations listed
      in the DEBUG_CONFIGURATIONS global property if it is set).  Libraries
      specified as "optimized" are appended to the the
      LINK_INTERFACE_LIBRARIES property.  Libraries specified as "general"
      (or without any keyword) are treated as if specified for both "debug"
      and "optimized".
 
        target_link_libraries(<target>
                              <LINK_PRIVATE|LINK_PUBLIC>
                                [[debug|optimized|general] <lib>] ...
                              [<LINK_PRIVATE|LINK_PUBLIC>
                                [[debug|optimized|general] <lib>] ...])
 
      The LINK_PUBLIC and LINK_PRIVATE modes can be used to specify both the
      link dependencies and the link interface in one command.  Libraries
      and targets following LINK_PUBLIC are linked to, and are made part of
      the LINK_INTERFACE_LIBRARIES.  Libraries and targets following
      LINK_PRIVATE are linked to, but are not made part of the
      LINK_INTERFACE_LIBRARIES.
 
      The library dependency graph is normally acyclic (a DAG), but in the
      case of mutually-dependent STATIC libraries CMake allows the graph to
      contain cycles (strongly connected components).  When another target
      links to one of the libraries CMake repeats the entire connected
      component.  For example, the code
 
        add_library(A STATIC a.c)
        add_library(B STATIC b.c)
        target_link_libraries(A B)
        target_link_libraries(B A)
        add_executable(main main.c)
        target_link_libraries(main A)
 
      links 'main' to 'A B A B'.  (While one repetition is usually
      sufficient, pathological object file and symbol arrangements can
      require more.  One may handle such cases by manually repeating the
      component in the last target_link_libraries call.  However, if two
      archives are really so interdependent they should probably be combined
      into a single archive.)
 
  try_compile
      Try building some code.
 
        try_compile(RESULT_VAR <bindir> <srcdir>
                    <projectName> [targetName] [CMAKE_FLAGS flags...]
                    [OUTPUT_VARIABLE <var>])
 
      Try building a project.  In this form, srcdir should contain a
      complete CMake project with a CMakeLists.txt file and all sources.
      The bindir and srcdir will not be deleted after this command is run.
      Specify targetName to build a specific target instead of the 'all' or
      'ALL_BUILD' target.
 
        try_compile(RESULT_VAR <bindir> <srcfile>
                    [CMAKE_FLAGS flags...]
                    [COMPILE_DEFINITIONS flags...]
                    [OUTPUT_VARIABLE <var>]
                    [COPY_FILE <fileName>])
 
      Try building a source file into an executable.  In this form the user
      need only supply a source file that defines a 'main'.  CMake will
      create a CMakeLists.txt file to build the source as an executable.
      Specify COPY_FILE to get a copy of the linked executable at the given
      fileName.
 
      In this version all files in bindir/CMakeFiles/CMakeTmp will be
      cleaned automatically.  For debugging, --debug-trycompile can be
      passed to cmake to avoid this clean.  However, multiple sequential
      try_compile operations reuse this single output directory.  If you use
      --debug-trycompile, you can only debug one try_compile call at a time.
      The recommended procedure is to configure with cmake all the way
      through once, then delete the cache entry associated with the
      try_compile call of interest, and then re-run cmake again with
      --debug-trycompile.
 
      Some extra flags that can be included are, INCLUDE_DIRECTORIES,
      LINK_DIRECTORIES, and LINK_LIBRARIES.  COMPILE_DEFINITIONS are
      -Ddefinition that will be passed to the compile line.  try_compile
      creates a CMakeList.txt file on the fly that looks like this:
 
        add_definitions( <expanded COMPILE_DEFINITIONS from calling cmake>)
        include_directories(${INCLUDE_DIRECTORIES})
        link_directories(${LINK_DIRECTORIES})
        add_executable(cmTryCompileExec sources)
        target_link_libraries(cmTryCompileExec ${LINK_LIBRARIES})
 
      In both versions of the command, if OUTPUT_VARIABLE is specified, then
      the output from the build process is stored in the given variable.
      The success or failure of the try_compile, i.e.  TRUE or FALSE
      respectively, is returned in RESULT_VAR.  CMAKE_FLAGS can be used to
      pass -DVAR:TYPE=VALUE flags to the cmake that is run during the build.
      Set variable CMAKE_TRY_COMPILE_CONFIGURATION to choose a build
      configuration.
 
  try_run
      Try compiling and then running some code.
 
        try_run(RUN_RESULT_VAR COMPILE_RESULT_VAR
                bindir srcfile [CMAKE_FLAGS <Flags>]
                [COMPILE_DEFINITIONS <flags>]
                [COMPILE_OUTPUT_VARIABLE comp]
                [RUN_OUTPUT_VARIABLE run]
                [OUTPUT_VARIABLE var]
                [ARGS <arg1> <arg2>...])
 
      Try compiling a srcfile.  Return TRUE or FALSE for success or failure
      in COMPILE_RESULT_VAR.  Then if the compile succeeded, run the
      executable and return its exit code in RUN_RESULT_VAR.  If the
      executable was built, but failed to run, then RUN_RESULT_VAR will be
      set to FAILED_TO_RUN.  COMPILE_OUTPUT_VARIABLE specifies the variable
      where the output from the compile step goes.  RUN_OUTPUT_VARIABLE
      specifies the variable where the output from the running executable
      goes.
 
      For compatibility reasons OUTPUT_VARIABLE is still supported, which
      gives you the output from the compile and run step combined.
 
      Cross compiling issues
 
      When cross compiling, the executable compiled in the first step
      usually cannot be run on the build host.  try_run() checks the
      CMAKE_CROSSCOMPILING variable to detect whether CMake is in
      crosscompiling mode.  If that's the case, it will still try to compile
      the executable, but it will not try to run the executable.  Instead it
      will create cache variables which must be filled by the user or by
      presetting them in some CMake script file to the values the executable
      would have produced if it would have been run on its actual target
      platform.  These variables are RUN_RESULT_VAR (explanation see above)
      and if RUN_OUTPUT_VARIABLE (or OUTPUT_VARIABLE) was used, an
      additional cache variable
      RUN_RESULT_VAR__COMPILE_RESULT_VAR__TRYRUN_OUTPUT.This is intended to
      hold stdout and stderr from the executable.
 
      In order to make cross compiling your project easier, use try_run only
      if really required.  If you use try_run, use RUN_OUTPUT_VARIABLE (or
      OUTPUT_VARIABLE) only if really required.  Using them will require
      that when crosscompiling, the cache variables will have to be set
      manually to the output of the executable.  You can also "guard" the
      calls to try_run with if(CMAKE_CROSSCOMPILING) and provide an
      easy-to-preset alternative for this case.
 
      Set variable CMAKE_TRY_COMPILE_CONFIGURATION to choose a build
      configuration.
 
  unset
      Unset a variable, cache variable, or environment variable.
 
        unset(<variable> [CACHE])
 
      Removes the specified variable causing it to become undefined.  If
      CACHE is present then the variable is removed from the cache instead
      of the current scope.
 
      <variable> can be an environment variable such as:
 
        unset(ENV{LD_LIBRARY_PATH})
 
      in which case the variable will be removed from the current
      environment.
 
  variable_watch
      Watch the CMake variable for change.
 
        variable_watch(<variable name> [<command to execute>])
 
      If the specified variable changes, the message will be printed about
      the variable being changed.  If the command is specified, the command
      will be executed.  The command will receive the following arguments:
      COMMAND(<variable> <access> <value> <current list file> <stack>)
 
  while
      Evaluate a group of commands while a condition is true
 
        while(condition)
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        endwhile(condition)
 
      All commands between while and the matching endwhile are recorded
      without being invoked.  Once the endwhile is evaluated, the recorded
      list of commands is invoked as long as the condition is true.  The
      condition is evaluated using the same logic as the if command.
 
------------------------------------------------------------------------------
Properties
 
  CMake Properties - Properties supported by CMake, the Cross-Platform Makefile Generator.
 
This is the documentation for the properties supported by CMake.  Properties
can have different scopes.  They can either be assigned to a source file, a
directory, a target or globally to CMake.  By modifying the values of
properties the behaviour of the build system can be customized.
 
------------------------------------------------------------------------------
Properties of Global Scope
 
  ALLOW_DUPLICATE_CUSTOM_TARGETS
      Allow duplicate custom targets to be created.
 
      Normally CMake requires that all targets built in a project have
      globally unique logical names (see policy CMP0002).  This is necessary
      to generate meaningful project file names in Xcode and VS IDE
      generators.  It also allows the target names to be referenced
      unambiguously.
 
      Makefile generators are capable of supporting duplicate custom target
      names.  For projects that care only about Makefile generators and do
      not wish to support Xcode or VS IDE generators, one may set this
      property to true to allow duplicate custom targets.  The property
      allows multiple add_custom_target command calls in different
      directories to specify the same target name.  However, setting this
      property will cause non-Makefile generators to produce an error and
      refuse to generate the project.
 
  DEBUG_CONFIGURATIONS
      Specify which configurations are for debugging.
 
      The value must be a semi-colon separated list of configuration names.
      Currently this property is used only by the target_link_libraries
      command (see its documentation for details).  Additional uses may be
      defined in the future.
 
      This property must be set at the top level of the project and before
      the first target_link_libraries command invocation.  If any entry in
      the list does not match a valid configuration for the project the
      behavior is undefined.
 
  DISABLED_FEATURES
      List of features which are disabled during the CMake run.
 
      List of features which are disabled during the CMake run.  By default
      it contains the names of all packages which were not found.  This is
      determined using the <NAME>_FOUND variables.  Packages which are
      searched QUIET are not listed.  A project can add its own features to
      this list.  This property is used by the macros in
      FeatureSummary.cmake.
 
  ENABLED_FEATURES
      List of features which are enabled during the CMake run.
 
      List of features which are enabled during the CMake run.  By default
      it contains the names of all packages which were found.  This is
      determined using the <NAME>_FOUND variables.  Packages which are
      searched QUIET are not listed.  A project can add its own features to
      this list.  This property is used by the macros in
      FeatureSummary.cmake.
 
  ENABLED_LANGUAGES
      Read-only property that contains the list of currently enabled
      languages
 
      Set to list of currently enabled languages.
 
  FIND_LIBRARY_USE_LIB64_PATHS
      Whether FIND_LIBRARY should automatically search lib64 directories.
 
      FIND_LIBRARY_USE_LIB64_PATHS is a boolean specifying whether the
      FIND_LIBRARY command should automatically search the lib64 variant of
      directories called lib in the search path when building 64-bit
      binaries.
 
  FIND_LIBRARY_USE_OPENBSD_VERSIONING
      Whether FIND_LIBRARY should find OpenBSD-style shared libraries.
 
      This property is a boolean specifying whether the FIND_LIBRARY command
      should find shared libraries with OpenBSD-style versioned extension:
      ".so.<major>.<minor>".  The property is set to true on OpenBSD and
      false on other platforms.
 
  GLOBAL_DEPENDS_DEBUG_MODE
      Enable global target dependency graph debug mode.
 
      CMake automatically analyzes the global inter-target dependency graph
      at the beginning of native build system generation.  This property
      causes it to display details of its analysis to stderr.
 
  GLOBAL_DEPENDS_NO_CYCLES
      Disallow global target dependency graph cycles.
 
      CMake automatically analyzes the global inter-target dependency graph
      at the beginning of native build system generation.  It reports an
      error if the dependency graph contains a cycle that does not consist
      of all STATIC library targets.  This property tells CMake to disallow
      all cycles completely, even among static libraries.
 
  IN_TRY_COMPILE
      Read-only property that is true during a try-compile configuration.
 
      True when building a project inside a TRY_COMPILE or TRY_RUN command.
 
  PACKAGES_FOUND
      List of packages which were found during the CMake run.
 
      List of packages which were found during the CMake run.  Whether a
      package has been found is determined using the <NAME>_FOUND variables.
 
  PACKAGES_NOT_FOUND
      List of packages which were not found during the CMake run.
 
      List of packages which were not found during the CMake run.  Whether a
      package has been found is determined using the <NAME>_FOUND variables.
 
  PREDEFINED_TARGETS_FOLDER
      Name of FOLDER for targets that are added automatically by CMake.
 
      If not set, CMake uses "CMakePredefinedTargets" as a default value for
      this property.  Targets such as INSTALL, PACKAGE and RUN_TESTS will be
      organized into this FOLDER.  See also the documentation for the FOLDER
      target property.
 
  REPORT_UNDEFINED_PROPERTIES
      If set, report any undefined properties to this file.
 
      If this property is set to a filename then when CMake runs it will
      report any properties or variables that were accessed but not defined
      into the filename specified in this property.
 
  RULE_LAUNCH_COMPILE
      Specify a launcher for compile rules.
 
      Makefile generators prefix compiler commands with the given launcher
      command line.  This is intended to allow launchers to intercept build
      problems with high granularity.  Non-Makefile generators currently
      ignore this property.
 
  RULE_LAUNCH_CUSTOM
      Specify a launcher for custom rules.
 
      Makefile generators prefix custom commands with the given launcher
      command line.  This is intended to allow launchers to intercept build
      problems with high granularity.  Non-Makefile generators currently
      ignore this property.
 
  RULE_LAUNCH_LINK
      Specify a launcher for link rules.
 
      Makefile generators prefix link and archive commands with the given
      launcher command line.  This is intended to allow launchers to
      intercept build problems with high granularity.  Non-Makefile
      generators currently ignore this property.
 
  RULE_MESSAGES
      Specify whether to report a message for each make rule.
 
      This property specifies whether Makefile generators should add a
      progress message describing what each build rule does.  If the
      property is not set the default is ON.  Set the property to OFF to
      disable granular messages and report only as each target completes.
      This is intended to allow scripted builds to avoid the build time cost
      of detailed reports.  If a CMAKE_RULE_MESSAGES cache entry exists its
      value initializes the value of this property.  Non-Makefile generators
      currently ignore this property.
 
  TARGET_ARCHIVES_MAY_BE_SHARED_LIBS
      Set if shared libraries may be named like archives.
 
      On AIX shared libraries may be named "lib<name>.a".  This property is
      set to true on such platforms.
 
  TARGET_SUPPORTS_SHARED_LIBS
      Does the target platform support shared libraries.
 
      TARGET_SUPPORTS_SHARED_LIBS is a boolean specifying whether the target
      platform supports shared libraries.  Basically all current general
      general purpose OS do so, the exception are usually embedded systems
      with no or special OSs.
 
  USE_FOLDERS
      Use the FOLDER target property to organize targets into folders.
 
      If not set, CMake treats this property as OFF by default.  CMake
      generators that are capable of organizing into a hierarchy of folders
      use the values of the FOLDER target property to name those folders.
      See also the documentation for the FOLDER target property.
 
  __CMAKE_DELETE_CACHE_CHANGE_VARS_
      Internal property
 
      Used to detect compiler changes, Do not set.
 
------------------------------------------------------------------------------
Properties on Directories
 
  ADDITIONAL_MAKE_CLEAN_FILES
      Additional files to clean during the make clean stage.
 
      A list of files that will be cleaned as a part of the "make clean"
      stage.
 
  CACHE_VARIABLES
      List of cache variables available in the current directory.
 
      This read-only property specifies the list of CMake cache variables
      currently defined.  It is intended for debugging purposes.
 
  CLEAN_NO_CUSTOM
      Should the output of custom commands be left.
 
      If this is true then the outputs of custom commands for this directory
      will not be removed during the "make clean" stage.
 
  COMPILE_DEFINITIONS
      Preprocessor definitions for compiling a directory's sources.
 
      The COMPILE_DEFINITIONS property may be set to a semicolon-separated
      list of preprocessor definitions using the syntax VAR or VAR=value.
      Function-style definitions are not supported.  CMake will
      automatically escape the value correctly for the native build system
      (note that CMake language syntax may require escapes to specify some
      values).  This property may be set on a per-configuration basis using
      the name COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case
      name (ex.  "COMPILE_DEFINITIONS_DEBUG").  This property will be
      initialized in each directory by its value in the directory's parent.
 
      CMake will automatically drop some definitions that are not supported
      by the native build tool.  The VS6 IDE does not support definition
      values with spaces (but NMake does).
 
      Disclaimer: Most native build tools have poor support for escaping
      certain values.  CMake has work-arounds for many cases but some values
      may just not be possible to pass correctly.  If a value does not seem
      to be escaped correctly, do not attempt to work-around the problem by
      adding escape sequences to the value.  Your work-around may break in a
      future version of CMake that has improved escape support.  Instead
      consider defining the macro in a (configured) header file.  Then
      report the limitation.  Known limitations include:
 
        #          - broken almost everywhere
        ;          - broken in VS IDE and Borland Makefiles
        ,          - broken in VS IDE
        %          - broken in some cases in NMake
        & |        - broken in some cases on MinGW
        ^ < > \"  - broken in most Make tools on Windows
 
      CMake does not reject these values outright because they do work in
      some cases.  Use with caution.
 
  COMPILE_DEFINITIONS_<CONFIG>
      Per-configuration preprocessor definitions in a directory.
 
      This is the configuration-specific version of COMPILE_DEFINITIONS.
      This property will be initialized in each directory by its value in
      the directory's parent.
 
 
  DEFINITIONS
      For CMake 2.4 compatibility only.  Use COMPILE_DEFINITIONS instead.
 
      This read-only property specifies the list of flags given so far to
      the add_definitions command.  It is intended for debugging purposes.
      Use the COMPILE_DEFINITIONS instead.
 
  EXCLUDE_FROM_ALL
      Exclude the directory from the all target of its parent.
 
      A property on a directory that indicates if its targets are excluded
      from the default build target.  If it is not, then with a Makefile for
      example typing make will cause the targets to be built.  The same
      concept applies to the default build of other generators.
 
  IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
      Specify #include line transforms for dependencies in a directory.
 
      This property specifies rules to transform macro-like #include lines
      during implicit dependency scanning of C and C++ source files.  The
      list of rules must be semicolon-separated with each entry of the form
      "A_MACRO(%)=value-with-%" (the % must be literal).  During dependency
      scanning occurrences of A_MACRO(...) on #include lines will be
      replaced by the value given with the macro argument substituted for
      '%'.  For example, the entry
 
        MYDIR(%)=<mydir/%>
 
      will convert lines of the form
 
        #include MYDIR(myheader.h)
 
      to
 
        #include <mydir/myheader.h>
 
      allowing the dependency to be followed.
 
      This property applies to sources in all targets within a directory.
      The property value is initialized in each directory by its value in
      the directory's parent.
 
  INCLUDE_DIRECTORIES
      List of preprocessor include file search directories.
 
      This property specifies the list of directories given so far to the
      include_directories command.  This property exists on directories and
      targets.  In addition to accepting values from the include_directories
      command, values may be set directly on any directory or any target
      using the set_property command.  A target gets its initial value for
      this property from the value of the directory property.  A directory
      gets its initial value from its parent directory if it has one.  Both
      directory and target property values are adjusted by calls to the
      include_directories command.
 
      The target property values are used by the generators to set the
      include paths for the compiler.  See also the include_directories
      command.
 
  INCLUDE_REGULAR_EXPRESSION
      Include file scanning regular expression.
 
      This read-only property specifies the regular expression used during
      dependency scanning to match include files that should be followed.
      See the include_regular_expression command.
 
  INTERPROCEDURAL_OPTIMIZATION
      Enable interprocedural optimization for targets in a directory.
 
      If set to true, enables interprocedural optimizations if they are
      known to be supported by the compiler.
 
  INTERPROCEDURAL_OPTIMIZATION_<CONFIG>
      Per-configuration interprocedural optimization for a directory.
 
      This is a per-configuration version of INTERPROCEDURAL_OPTIMIZATION.
      If set, this property overrides the generic property for the named
      configuration.
 
  LINK_DIRECTORIES
      List of linker search directories.
 
      This read-only property specifies the list of directories given so far
      to the link_directories command.  It is intended for debugging
      purposes.
 
  LISTFILE_STACK
      The current stack of listfiles being processed.
 
      This property is mainly useful when trying to debug errors in your
      CMake scripts.  It returns a list of what list files are currently
      being processed, in order.  So if one listfile does an INCLUDE command
      then that is effectively pushing the included listfile onto the stack.
 
  MACROS
      List of macro commands available in the current directory.
 
      This read-only property specifies the list of CMake macros currently
      defined.  It is intended for debugging purposes.  See the macro
      command.
 
  PARENT_DIRECTORY
      Source directory that added current subdirectory.
 
      This read-only property specifies the source directory that added the
      current source directory as a subdirectory of the build.  In the
      top-level directory the value is the empty-string.
 
  RULE_LAUNCH_COMPILE
      Specify a launcher for compile rules.
 
      See the global property of the same name for details.  This overrides
      the global property for a directory.
 
  RULE_LAUNCH_CUSTOM
      Specify a launcher for custom rules.
 
      See the global property of the same name for details.  This overrides
      the global property for a directory.
 
  RULE_LAUNCH_LINK
      Specify a launcher for link rules.
 
      See the global property of the same name for details.  This overrides
      the global property for a directory.
 
  TEST_INCLUDE_FILE
      A cmake file that will be included when ctest is run.
 
      If you specify TEST_INCLUDE_FILE, that file will be included and
      processed when ctest is run on the directory.
 
  VARIABLES
      List of variables defined in the current directory.
 
      This read-only property specifies the list of CMake variables
      currently defined.  It is intended for debugging purposes.
 
------------------------------------------------------------------------------
Properties on Targets
 
  <CONFIG>_OUTPUT_NAME
      Old per-configuration target file base name.
 
      This is a configuration-specific version of OUTPUT_NAME.  Use
      OUTPUT_NAME_<CONFIG> instead.
 
  <CONFIG>_POSTFIX
      Postfix to append to the target file name for configuration <CONFIG>.
 
      When building with configuration <CONFIG> the value of this property
      is appended to the target file name built on disk.  For non-executable
      targets, this property is initialized by the value of the variable
      CMAKE_<CONFIG>_POSTFIX if it is set when a target is created.  This
      property is ignored on the Mac for Frameworks and App Bundles.
 
  ARCHIVE_OUTPUT_DIRECTORY
      Output directory in which to build ARCHIVE target files.
 
      This property specifies the directory into which archive target files
      should be built.  Multi-configuration generators (VS, Xcode) append a
      per-configuration subdirectory to the specified directory.  There are
      three kinds of target files that may be built: archive, library, and
      runtime.  Executables are always treated as runtime targets.  Static
      libraries are always treated as archive targets.  Module libraries are
      always treated as library targets.  For non-DLL platforms shared
      libraries are treated as library targets.  For DLL platforms the DLL
      part of a shared library is treated as a runtime target and the
      corresponding import library is treated as an archive target.  All
      Windows-based systems including Cygwin are DLL platforms.  This
      property is initialized by the value of the variable
      CMAKE_ARCHIVE_OUTPUT_DIRECTORY if it is set when a target is created.
 
  ARCHIVE_OUTPUT_DIRECTORY_<CONFIG>
      Per-configuration output directory for ARCHIVE target files.
 
      This is a per-configuration version of ARCHIVE_OUTPUT_DIRECTORY, but
      multi-configuration generators (VS, Xcode) do NOT append a
      per-configuration subdirectory to the specified directory.  This
      property is initialized by the value of the variable
      CMAKE_ARCHIVE_OUTPUT_DIRECTORY_<CONFIG> if it is set when a target is
      created.
 
  ARCHIVE_OUTPUT_NAME
      Output name for ARCHIVE target files.
 
      This property specifies the base name for archive target files.  It
      overrides OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties.  There are
      three kinds of target files that may be built: archive, library, and
      runtime.  Executables are always treated as runtime targets.  Static
      libraries are always treated as archive targets.  Module libraries are
      always treated as library targets.  For non-DLL platforms shared
      libraries are treated as library targets.  For DLL platforms the DLL
      part of a shared library is treated as a runtime target and the
      corresponding import library is treated as an archive target.  All
      Windows-based systems including Cygwin are DLL platforms.
 
  ARCHIVE_OUTPUT_NAME_<CONFIG>
      Per-configuration output name for ARCHIVE target files.
 
      This is the configuration-specific version of ARCHIVE_OUTPUT_NAME.
 
  AUTOMOC
      Should the target be processed with automoc (for Qt projects).
 
      AUTOMOC is a boolean specifying whether CMake will handle the Qt moc
      preprocessor automatically, i.e.  without having to use the
      QT4_WRAP_CPP() macro.  Currently Qt4 is supported.  When this property
      is set to TRUE, CMake will scan the source files at build time and
      invoke moc accordingly.  If an #include statement like #include
      "moc_foo.cpp" is found, the Q_OBJECT class declaration is expected in
      the header, and moc is run on the header file.  If an #include
      statement like #include "foo.moc" is found, then a Q_OBJECT is
      expected in the current source file and moc is run on the file itself.
      Additionally, all header files are parsed for Q_OBJECT macros, and if
      found, moc is also executed on those files.  The resulting moc files,
      which are not included as shown above in any of the source files are
      included in a generated <targetname>_automoc.cpp file, which is
      compiled as part of the target.This property is initialized by the
      value of the variable CMAKE_AUTOMOC if it is set when a target is
      created.
 
      Additional command line options for moc can be set via the
      AUTOMOC_MOC_OPTIONS property.
 
      By setting the CMAKE_AUTOMOC_RELAXED_MODE variable to TRUE the rules
      for searching the files which will be processed by moc can be relaxed.
      See the documentation for this variable for more details.
 
  AUTOMOC_MOC_OPTIONS
      Additional options for moc when using automoc (see the AUTOMOC
      property)
 
      This property is only used if the AUTOMOC property is set to TRUE for
      this target.  In this case, it holds additional command line options
      which will be used when moc is executed during the build, i.e.  it is
      equivalent to the optional OPTIONS argument of the qt4_wrap_cpp()
      macro.
 
      By default it is empty.
 
  BUILD_WITH_INSTALL_RPATH
      Should build tree targets have install tree rpaths.
 
      BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the
      target in the build tree with the INSTALL_RPATH.  This takes
      precedence over SKIP_BUILD_RPATH and avoids the need for relinking
      before installation.  This property is initialized by the value of the
      variable CMAKE_BUILD_WITH_INSTALL_RPATH if it is set when a target is
      created.
 
  BUNDLE
      This target is a CFBundle on the Mac.
 
      If a module library target has this property set to true it will be
      built as a CFBundle when built on the mac.  It will have the directory
      structure required for a CFBundle and will be suitable to be used for
      creating Browser Plugins or other application resources.
 
  BUNDLE_EXTENSION
      The file extension used to name a BUNDLE target on the Mac.
 
      The default value is "bundle" - you can also use "plugin" or whatever
      file extension is required by the host app for your bundle.
 
  COMPILE_DEFINITIONS
      Preprocessor definitions for compiling a target's sources.
 
      The COMPILE_DEFINITIONS property may be set to a semicolon-separated
      list of preprocessor definitions using the syntax VAR or VAR=value.
      Function-style definitions are not supported.  CMake will
      automatically escape the value correctly for the native build system
      (note that CMake language syntax may require escapes to specify some
      values).  This property may be set on a per-configuration basis using
      the name COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case
      name (ex.  "COMPILE_DEFINITIONS_DEBUG").
 
      CMake will automatically drop some definitions that are not supported
      by the native build tool.  The VS6 IDE does not support definition
      values with spaces (but NMake does).
 
      Contents of COMPILE_DEFINITIONS may use "generator expressions" with
      the syntax "$<...>".  Generator expressions are evaluted during build
      system generation to produce information specific to each build
      configuration.  Valid expressions are:
 
        $<0:...>                  = empty string (ignores "...")
        $<1:...>                  = content of "..."
        $<CONFIG:cfg>            = '1' if config is "cfg", else '0'
        $<CONFIGURATION>          = configuration name
        $<BOOL:...>              = '1' if the '...' is true, else '0'
        $<STREQUAL:a,b>          = '1' if a is STREQUAL b, else '0'
        $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
        $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
        $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
        $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
        $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)
 
      where "tgt" is the name of a target.  Target file expressions produce
      a full path, but _DIR and _NAME versions can produce the directory and
      file name components:
 
        $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
        $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
        $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>
 
     
 
        $<TARGET_PROPERTY:tgt,prop>  = The value of the property prop
 
      on the target tgt.  Note that tgt is not added as a dependency of
 
      the target this expression is evaluated on.
 
      Boolean expressions:
 
        $<AND:?[,?]...>          = '1' if all '?' are '1', else '0'
        $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
        $<NOT:?>                  = '0' if '?' is '1', else '1'
 
      where '?' is always either '0' or '1'.
 
      Expressions with an implicit 'this' target:
 
        $<TARGET_PROPERTY:prop>  = The value of the property prop on
 
      the target on which the generator expression is evaluated.
 
      Disclaimer: Most native build tools have poor support for escaping
      certain values.  CMake has work-arounds for many cases but some values
      may just not be possible to pass correctly.  If a value does not seem
      to be escaped correctly, do not attempt to work-around the problem by
      adding escape sequences to the value.  Your work-around may break in a
      future version of CMake that has improved escape support.  Instead
      consider defining the macro in a (configured) header file.  Then
      report the limitation.  Known limitations include:
 
        #          - broken almost everywhere
        ;          - broken in VS IDE and Borland Makefiles
        ,          - broken in VS IDE
        %          - broken in some cases in NMake
        & |        - broken in some cases on MinGW
        ^ < > \"  - broken in most Make tools on Windows
 
      CMake does not reject these values outright because they do work in
      some cases.  Use with caution.
 
  COMPILE_DEFINITIONS_<CONFIG>
      Per-configuration preprocessor definitions on a target.
 
      This is the configuration-specific version of COMPILE_DEFINITIONS.
 
  COMPILE_FLAGS
      Additional flags to use when compiling this target's sources.
 
      The COMPILE_FLAGS property sets additional compiler flags used to
      build sources within the target.  Use COMPILE_DEFINITIONS to pass
      additional preprocessor definitions.
 
  DEBUG_POSTFIX
      See target property <CONFIG>_POSTFIX.
 
      This property is a special case of the more-general <CONFIG>_POSTFIX
      property for the DEBUG configuration.
 
  DEFINE_SYMBOL
      Define a symbol when compiling this target's sources.
 
      DEFINE_SYMBOL sets the name of the preprocessor symbol defined when
      compiling sources in a shared library.  If not set here then it is set
      to target_EXPORTS by default (with some substitutions if the target is
      not a valid C identifier).  This is useful for headers to know whether
      they are being included from inside their library our outside to
      properly setup dllexport/dllimport decorations.
 
  ENABLE_EXPORTS
      Specify whether an executable exports symbols for loadable modules.
 
      Normally an executable does not export any symbols because it is the
      final program.  It is possible for an executable to export symbols to
      be used by loadable modules.  When this property is set to true CMake
      will allow other targets to "link" to the executable with the
      TARGET_LINK_LIBRARIES command.  On all platforms a target-level
      dependency on the executable is created for targets that link to it.
      For DLL platforms an import library will be created for the exported
      symbols and then used for linking.  All Windows-based systems
      including Cygwin are DLL platforms.  For non-DLL platforms that
      require all symbols to be resolved at link time, such as Mac OS X, the
      module will "link" to the executable using a flag like
      "-bundle_loader".  For other non-DLL platforms the link rule is simply
      ignored since the dynamic loader will automatically bind symbols when
      the module is loaded.
 
  EXCLUDE_FROM_ALL
      Exclude the target from the all target.
 
      A property on a target that indicates if the target is excluded from
      the default build target.  If it is not, then with a Makefile for
      example typing make will cause this target to be built.  The same
      concept applies to the default build of other generators.  Installing
      a target with EXCLUDE_FROM_ALL set to true has undefined behavior.
 
  EchoString
      A message to be displayed when the target is built.
 
      A message to display on some generators (such as makefiles) when the
      target is built.
 
  FOLDER
      Set the folder name.  Use to organize targets in an IDE.
 
      Targets with no FOLDER property will appear as top level entities in
      IDEs like Visual Studio.  Targets with the same FOLDER property value
      will appear next to each other in a folder of that name.  To nest
      folders, use FOLDER values such as 'GUI/Dialogs' with '/' characters
      separating folder levels.
 
  FRAMEWORK
      This target is a framework on the Mac.
 
      If a shared library target has this property set to true it will be
      built as a framework when built on the mac.  It will have the
      directory structure required for a framework and will be suitable to
      be used with the -framework option
 
  Fortran_FORMAT
      Set to FIXED or FREE to indicate the Fortran source layout.
 
      This property tells CMake whether the Fortran source files in a target
      use fixed-format or free-format.  CMake will pass the corresponding
      format flag to the compiler.  Use the source-specific Fortran_FORMAT
      property to change the format of a specific source file.  If the
      variable CMAKE_Fortran_FORMAT is set when a target is created its
      value is used to initialize this property.
 
  Fortran_MODULE_DIRECTORY
      Specify output directory for Fortran modules provided by the target.
 
      If the target contains Fortran source files that provide modules and
      the compiler supports a module output directory this specifies the
      directory in which the modules will be placed.  When this property is
      not set the modules will be placed in the build directory
      corresponding to the target's source directory.  If the variable
      CMAKE_Fortran_MODULE_DIRECTORY is set when a target is created its
      value is used to initialize this property.
 
      Note that some compilers will automatically search the module output
      directory for modules USEd during compilation but others will not.  If
      your sources USE modules their location must be specified by
      INCLUDE_DIRECTORIES regardless of this property.
 
  GENERATOR_FILE_NAME
      Generator's file for this target.
 
      An internal property used by some generators to record the name of
      project or dsp file associated with this target.
 
  GNUtoMS
      Convert GNU import library (.dll.a) to MS format (.lib).
 
      When linking a shared library or executable that exports symbols using
      GNU tools on Windows (MinGW/MSYS) with Visual Studio installed convert
      the import library (.dll.a) from GNU to MS format (.lib).  Both import
      libraries will be installed by install(TARGETS) and exported by
      install(EXPORT) and export() to be linked by applications with either
      GNU- or MS-compatible tools.
 
      If the variable CMAKE_GNUtoMS is set when a target is created its
      value is used to initialize this property.  The variable must be set
      prior to the first command that enables a language such as project()
      or enable_language().  CMake provides the variable as an option to the
      user automatically when configuring on Windows with GNU tools.
 
  HAS_CXX
      Link the target using the C++ linker tool (obsolete).
 
      This is equivalent to setting the LINKER_LANGUAGE property to CXX.
      See that property's documentation for details.
 
  IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
      Specify #include line transforms for dependencies in a target.
 
      This property specifies rules to transform macro-like #include lines
      during implicit dependency scanning of C and C++ source files.  The
      list of rules must be semicolon-separated with each entry of the form
      "A_MACRO(%)=value-with-%" (the % must be literal).  During dependency
      scanning occurrences of A_MACRO(...) on #include lines will be
      replaced by the value given with the macro argument substituted for
      '%'.  For example, the entry
 
        MYDIR(%)=<mydir/%>
 
      will convert lines of the form
 
        #include MYDIR(myheader.h)
 
      to
 
        #include <mydir/myheader.h>
 
      allowing the dependency to be followed.
 
      This property applies to sources in the target on which it is set.
 
  IMPORTED
      Read-only indication of whether a target is IMPORTED.
 
      The boolean value of this property is true for targets created with
      the IMPORTED option to add_executable or add_library.  It is false for
      targets built within the project.
 
  IMPORTED_CONFIGURATIONS
      Configurations provided for an IMPORTED target.
 
      Set this to the list of configuration names available for an IMPORTED
      target.  The names correspond to configurations defined in the project
      from which the target is imported.  If the importing project uses a
      different set of configurations the names may be mapped using the
      MAP_IMPORTED_CONFIG_<CONFIG> property.  Ignored for non-imported
      targets.
 
  IMPORTED_IMPLIB
      Full path to the import library for an IMPORTED target.
 
      Set this to the location of the ".lib" part of a windows DLL.  Ignored
      for non-imported targets.
 
  IMPORTED_IMPLIB_<CONFIG>
      <CONFIG>-specific version of IMPORTED_IMPLIB property.
 
      Configuration names correspond to those provided by the project from
      which the target is imported.
 
  IMPORTED_LINK_DEPENDENT_LIBRARIES
      Dependent shared libraries of an imported shared library.
 
      Shared libraries may be linked to other shared libraries as part of
      their implementation.  On some platforms the linker searches for the
      dependent libraries of shared libraries they are including in the
      link.  Set this property to the list of dependent shared libraries of
      an imported library.  The list should be disjoint from the list of
      interface libraries in the IMPORTED_LINK_INTERFACE_LIBRARIES property.
      On platforms requiring dependent shared libraries to be found at link
      time CMake uses this list to add appropriate files or paths to the
      link command line.  Ignored for non-imported targets.
 
  IMPORTED_LINK_DEPENDENT_LIBRARIES_<CONFIG>
      <CONFIG>-specific version of IMPORTED_LINK_DEPENDENT_LIBRARIES.
 
      Configuration names correspond to those provided by the project from
      which the target is imported.  If set, this property completely
      overrides the generic property for the named configuration.
 
  IMPORTED_LINK_INTERFACE_LANGUAGES
      Languages compiled into an IMPORTED static library.
 
      Set this to the list of languages of source files compiled to produce
      a STATIC IMPORTED library (such as "C" or "CXX").  CMake accounts for
      these languages when computing how to link a target to the imported
      library.  For example, when a C executable links to an imported C++
      static library CMake chooses the C++ linker to satisfy language
      runtime dependencies of the static library.
 
      This property is ignored for targets that are not STATIC libraries.
      This property is ignored for non-imported targets.
 
  IMPORTED_LINK_INTERFACE_LANGUAGES_<CONFIG>
      <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_LANGUAGES.
 
      Configuration names correspond to those provided by the project from
      which the target is imported.  If set, this property completely
      overrides the generic property for the named configuration.
 
  IMPORTED_LINK_INTERFACE_LIBRARIES
      Transitive link interface of an IMPORTED target.
 
      Set this to the list of libraries whose interface is included when an
      IMPORTED library target is linked to another target.  The libraries
      will be included on the link line for the target.  Unlike the
      LINK_INTERFACE_LIBRARIES property, this property applies to all
      imported target types, including STATIC libraries.  This property is
      ignored for non-imported targets.
 
  IMPORTED_LINK_INTERFACE_LIBRARIES_<CONFIG>
      <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_LIBRARIES.
 
      Configuration names correspond to those provided by the project from
      which the target is imported.  If set, this property completely
      overrides the generic property for the named configuration.
 
  IMPORTED_LINK_INTERFACE_MULTIPLICITY
      Repetition count for cycles of IMPORTED static libraries.
 
      This is LINK_INTERFACE_MULTIPLICITY for IMPORTED targets.
 
  IMPORTED_LINK_INTERFACE_MULTIPLICITY_<CONFIG>
      <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_MULTIPLICITY.
 
      If set, this property completely overrides the generic property for
      the named configuration.
 
  IMPORTED_LOCATION
      Full path to the main file on disk for an IMPORTED target.
 
      Set this to the location of an IMPORTED target file on disk.  For
      executables this is the location of the executable file.  For bundles
      on OS X this is the location of the executable file inside
      Contents/MacOS under the application bundle folder.  For static
      libraries and modules this is the location of the library or module.
      For shared libraries on non-DLL platforms this is the location of the
      shared library.  For frameworks on OS X this is the location of the
      library file symlink just inside the framework folder.  For DLLs this
      is the location of the ".dll" part of the library.  For UNKNOWN
      libraries this is the location of the file to be linked.  Ignored for
      non-imported targets.
 
      Projects may skip IMPORTED_LOCATION if the configuration-specific
      property IMPORTED_LOCATION_<CONFIG> is set.  To get the location of an
      imported target read one of the LOCATION or LOCATION_<CONFIG>
      properties.
 
  IMPORTED_LOCATION_<CONFIG>
      <CONFIG>-specific version of IMPORTED_LOCATION property.
 
      Configuration names correspond to those provided by the project from
      which the target is imported.
 
  IMPORTED_NO_SONAME
      Specifies that an IMPORTED shared library target has no "soname".
 
      Set this property to true for an imported shared library file that has
      no "soname" field.  CMake may adjust generated link commands for some
      platforms to prevent the linker from using the path to the library in
      place of its missing soname.  Ignored for non-imported targets.
 
  IMPORTED_NO_SONAME_<CONFIG>
      <CONFIG>-specific version of IMPORTED_NO_SONAME property.
 
      Configuration names correspond to those provided by the project from
      which the target is imported.
 
  IMPORTED_SONAME
      The "soname" of an IMPORTED target of shared library type.
 
      Set this to the "soname" embedded in an imported shared library.  This
      is meaningful only on platforms supporting the feature.  Ignored for
      non-imported targets.
 
  IMPORTED_SONAME_<CONFIG>
      <CONFIG>-specific version of IMPORTED_SONAME property.
 
      Configuration names correspond to those provided by the project from
      which the target is imported.
 
  IMPORT_PREFIX
      What comes before the import library name.
 
      Similar to the target property PREFIX, but used for import libraries
      (typically corresponding to a DLL) instead of regular libraries.  A
      target property that can be set to override the prefix (such as "lib")
      on an import library name.
 
  IMPORT_SUFFIX
      What comes after the import library name.
 
      Similar to the target property SUFFIX, but used for import libraries
      (typically corresponding to a DLL) instead of regular libraries.  A
      target property that can be set to override the suffix (such as
      ".lib") on an import library name.
 
  INCLUDE_DIRECTORIES
      List of preprocessor include file search directories.
 
      This property specifies the list of directories given so far to the
      include_directories command.  This property exists on directories and
      targets.  In addition to accepting values from the include_directories
      command, values may be set directly on any directory or any target
      using the set_property command.  A target gets its initial value for
      this property from the value of the directory property.  A directory
      gets its initial value from its parent directory if it has one.  Both
      directory and target property values are adjusted by calls to the
      include_directories command.
 
      The target property values are used by the generators to set the
      include paths for the compiler.  See also the include_directories
      command.
 
      Contents of INCLUDE_DIRECTORIES may use "generator expressions" with
      the syntax "$<...>".  Generator expressions are evaluted during build
      system generation to produce information specific to each build
      configuration.  Valid expressions are:
 
        $<0:...>                  = empty string (ignores "...")
        $<1:...>                  = content of "..."
        $<CONFIG:cfg>            = '1' if config is "cfg", else '0'
        $<CONFIGURATION>          = configuration name
        $<BOOL:...>              = '1' if the '...' is true, else '0'
        $<STREQUAL:a,b>          = '1' if a is STREQUAL b, else '0'
        $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
        $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
        $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
        $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
        $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)
 
      where "tgt" is the name of a target.  Target file expressions produce
      a full path, but _DIR and _NAME versions can produce the directory and
      file name components:
 
        $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
        $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
        $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>
 
     
 
        $<TARGET_PROPERTY:tgt,prop>  = The value of the property prop
 
      on the target tgt.  Note that tgt is not added as a dependency of
 
      the target this expression is evaluated on.
 
      Boolean expressions:
 
        $<AND:?[,?]...>          = '1' if all '?' are '1', else '0'
        $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
        $<NOT:?>                  = '0' if '?' is '1', else '1'
 
      where '?' is always either '0' or '1'.
 
      Expressions with an implicit 'this' target:
 
        $<TARGET_PROPERTY:prop>  = The value of the property prop on
 
      the target on which the generator expression is evaluated.
 
 
  INSTALL_NAME_DIR
      Mac OSX directory name for installed targets.
 
      INSTALL_NAME_DIR is a string specifying the directory portion of the
      "install_name" field of shared libraries on Mac OSX to use in the
      installed targets.
 
  INSTALL_RPATH
      The rpath to use for installed targets.
 
      A semicolon-separated list specifying the rpath to use in installed
      targets (for platforms that support it).  This property is initialized
      by the value of the variable CMAKE_INSTALL_RPATH if it is set when a
      target is created.
 
  INSTALL_RPATH_USE_LINK_PATH
      Add paths to linker search and installed rpath.
 
      INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true will
      append directories in the linker search path and outside the project
      to the INSTALL_RPATH.  This property is initialized by the value of
      the variable CMAKE_INSTALL_RPATH_USE_LINK_PATH if it is set when a
      target is created.
 
  INTERPROCEDURAL_OPTIMIZATION
      Enable interprocedural optimization for a target.
 
      If set to true, enables interprocedural optimizations if they are
      known to be supported by the compiler.
 
  INTERPROCEDURAL_OPTIMIZATION_<CONFIG>
      Per-configuration interprocedural optimization for a target.
 
      This is a per-configuration version of INTERPROCEDURAL_OPTIMIZATION.
      If set, this property overrides the generic property for the named
      configuration.
 
  LABELS
      Specify a list of text labels associated with a target.
 
      Target label semantics are currently unspecified.
 
  LIBRARY_OUTPUT_DIRECTORY
      Output directory in which to build LIBRARY target files.
 
      This property specifies the directory into which library target files
      should be built.  Multi-configuration generators (VS, Xcode) append a
      per-configuration subdirectory to the specified directory.  There are
      three kinds of target files that may be built: archive, library, and
      runtime.  Executables are always treated as runtime targets.  Static
      libraries are always treated as archive targets.  Module libraries are
      always treated as library targets.  For non-DLL platforms shared
      libraries are treated as library targets.  For DLL platforms the DLL
      part of a shared library is treated as a runtime target and the
      corresponding import library is treated as an archive target.  All
      Windows-based systems including Cygwin are DLL platforms.  This
      property is initialized by the value of the variable
      CMAKE_LIBRARY_OUTPUT_DIRECTORY if it is set when a target is created.
 
  LIBRARY_OUTPUT_DIRECTORY_<CONFIG>
      Per-configuration output directory for LIBRARY target files.
 
      This is a per-configuration version of LIBRARY_OUTPUT_DIRECTORY, but
      multi-configuration generators (VS, Xcode) do NOT append a
      per-configuration subdirectory to the specified directory.  This
      property is initialized by the value of the variable
      CMAKE_LIBRARY_OUTPUT_DIRECTORY_<CONFIG> if it is set when a target is
      created.
 
  LIBRARY_OUTPUT_NAME
      Output name for LIBRARY target files.
 
      This property specifies the base name for library target files.  It
      overrides OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties.  There are
      three kinds of target files that may be built: archive, library, and
      runtime.  Executables are always treated as runtime targets.  Static
      libraries are always treated as archive targets.  Module libraries are
      always treated as library targets.  For non-DLL platforms shared
      libraries are treated as library targets.  For DLL platforms the DLL
      part of a shared library is treated as a runtime target and the
      corresponding import library is treated as an archive target.  All
      Windows-based systems including Cygwin are DLL platforms.
 
  LIBRARY_OUTPUT_NAME_<CONFIG>
      Per-configuration output name for LIBRARY target files.
 
      This is the configuration-specific version of LIBRARY_OUTPUT_NAME.
 
  LINKER_LANGUAGE
      Specifies language whose compiler will invoke the linker.
 
      For executables, shared libraries, and modules, this sets the language
      whose compiler is used to link the target (such as "C" or "CXX").  A
      typical value for an executable is the language of the source file
      providing the program entry point (main).  If not set, the language
      with the highest linker preference value is the default.  See
      documentation of CMAKE_<LANG>_LINKER_PREFERENCE variables.
 
  LINK_DEPENDS
      Additional files on which a target binary depends for linking.
 
      Specifies a semicolon-separated list of full-paths to files on which
      the link rule for this target depends.  The target binary will be
      linked if any of the named files is newer than it.
 
      This property is ignored by non-Makefile generators.  It is intended
      to specify dependencies on "linker scripts" for custom Makefile link
      rules.
 
  LINK_FLAGS
      Additional flags to use when linking this target.
 
      The LINK_FLAGS property can be used to add extra flags to the link
      step of a target.  LINK_FLAGS_<CONFIG> will add to the configuration
      <CONFIG>, for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO.
 
  LINK_FLAGS_<CONFIG>
      Per-configuration linker flags for a target.
 
      This is the configuration-specific version of LINK_FLAGS.
 
  LINK_INTERFACE_LIBRARIES
      List public interface libraries for a shared library or executable.
 
      By default linking to a shared library target transitively links to
      targets with which the library itself was linked.  For an executable
      with exports (see the ENABLE_EXPORTS property) no default transitive
      link dependencies are used.  This property replaces the default
      transitive link dependencies with an explicit list.  When the target
      is linked into another target the libraries listed (and recursively
      their link interface libraries) will be provided to the other target
      also.  If the list is empty then no transitive link dependencies will
      be incorporated when this target is linked into another target even if
      the default set is non-empty.  This property is initialized by the
      value of the variable CMAKE_LINK_INTERFACE_LIBRARIES if it is set when
      a target is created.  This property is ignored for STATIC libraries.
 
  LINK_INTERFACE_LIBRARIES_<CONFIG>
      Per-configuration list of public interface libraries for a target.
 
      This is the configuration-specific version of
      LINK_INTERFACE_LIBRARIES.  If set, this property completely overrides
      the generic property for the named configuration.
 
  LINK_INTERFACE_MULTIPLICITY
      Repetition count for STATIC libraries with cyclic dependencies.
 
      When linking to a STATIC library target with cyclic dependencies the
      linker may need to scan more than once through the archives in the
      strongly connected component of the dependency graph.  CMake by
      default constructs the link line so that the linker will scan through
      the component at least twice.  This property specifies the minimum
      number of scans if it is larger than the default.  CMake uses the
      largest value specified by any target in a component.
 
  LINK_INTERFACE_MULTIPLICITY_<CONFIG>
      Per-configuration repetition count for cycles of STATIC libraries.
 
      This is the configuration-specific version of
      LINK_INTERFACE_MULTIPLICITY.  If set, this property completely
      overrides the generic property for the named configuration.
 
  LINK_SEARCH_END_STATIC
      End a link line such that static system libraries are used.
 
      Some linkers support switches such as -Bstatic and -Bdynamic to
      determine whether to use static or shared libraries for -lXXX options.
      CMake uses these options to set the link type for libraries whose full
      paths are not known or (in some cases) are in implicit link
      directories for the platform.  By default CMake adds an option at the
      end of the library list (if necessary) to set the linker search type
      back to its starting type.  This property switches the final linker
      search type to -Bstatic regardless of how it started.  See also
      LINK_SEARCH_START_STATIC.
 
  LINK_SEARCH_START_STATIC
      Assume the linker looks for static libraries by default.
 
      Some linkers support switches such as -Bstatic and -Bdynamic to
      determine whether to use static or shared libraries for -lXXX options.
      CMake uses these options to set the link type for libraries whose full
      paths are not known or (in some cases) are in implicit link
      directories for the platform.  By default the linker search type is
      assumed to be -Bdynamic at the beginning of the library list.  This
      property switches the assumption to -Bstatic.  It is intended for use
      when linking an executable statically (e.g.  with the GNU -static
      option).  See also LINK_SEARCH_END_STATIC.
 
  LOCATION
      Read-only location of a target on disk.
 
      For an imported target, this read-only property returns the value of
      the LOCATION_<CONFIG> property for an unspecified configuration
      <CONFIG> provided by the target.
 
      For a non-imported target, this property is provided for compatibility
      with CMake 2.4 and below.  It was meant to get the location of an
      executable target's output file for use in add_custom_command.  The
      path may contain a build-system-specific portion that is replaced at
      build time with the configuration getting built (such as
      "$(ConfigurationName)" in VS).  In CMake 2.6 and above
      add_custom_command automatically recognizes a target name in its
      COMMAND and DEPENDS options and computes the target location.  In
      CMake 2.8.4 and above add_custom_command recognizes generator
      expressions to refer to target locations anywhere in the command.
      Therefore this property is not needed for creating custom commands.
 
      Do not set properties that affect the location of a target after
      reading this property.  These include properties whose names match
      "(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CONFIG>)?",
      "(IMPLIB_)?(PREFIX|SUFFIX)", or "LINKER_LANGUAGE".  Failure to follow
      this rule is not diagnosed and leaves the location of the target
      undefined.
 
  LOCATION_<CONFIG>
      Read-only property providing a target location on disk.
 
      A read-only property that indicates where a target's main file is
      located on disk for the configuration <CONFIG>.  The property is
      defined only for library and executable targets.  An imported target
      may provide a set of configurations different from that of the
      importing project.  By default CMake looks for an exact-match but
      otherwise uses an arbitrary available configuration.  Use the
      MAP_IMPORTED_CONFIG_<CONFIG> property to map imported configurations
      explicitly.
 
      Do not set properties that affect the location of a target after
      reading this property.  These include properties whose names match
      "(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CONFIG>)?",
      "(IMPLIB_)?(PREFIX|SUFFIX)", or "LINKER_LANGUAGE".  Failure to follow
      this rule is not diagnosed and leaves the location of the target
      undefined.
 
  MACOSX_BUNDLE
      Build an executable as an application bundle on Mac OS X.
 
      When this property is set to true the executable when built on Mac OS
      X will be created as an application bundle.  This makes it a GUI
      executable that can be launched from the Finder.  See the
      MACOSX_BUNDLE_INFO_PLIST target property for information about
      creation of the Info.plist file for the application bundle.  This
      property is initialized by the value of the variable
      CMAKE_MACOSX_BUNDLE if it is set when a target is created.
 
  MACOSX_BUNDLE_INFO_PLIST
      Specify a custom Info.plist template for a Mac OS X App Bundle.
 
      An executable target with MACOSX_BUNDLE enabled will be built as an
      application bundle on Mac OS X.  By default its Info.plist file is
      created by configuring a template called MacOSXBundleInfo.plist.in
      located in the CMAKE_MODULE_PATH.  This property specifies an
      alternative template file name which may be a full path.
 
      The following target properties may be set to specify content to be
      configured into the file:
 
        MACOSX_BUNDLE_INFO_STRING
        MACOSX_BUNDLE_ICON_FILE
        MACOSX_BUNDLE_GUI_IDENTIFIER
        MACOSX_BUNDLE_LONG_VERSION_STRING
        MACOSX_BUNDLE_BUNDLE_NAME
        MACOSX_BUNDLE_SHORT_VERSION_STRING
        MACOSX_BUNDLE_BUNDLE_VERSION
        MACOSX_BUNDLE_COPYRIGHT
 
      CMake variables of the same name may be set to affect all targets in a
      directory that do not have each specific property set.  If a custom
      Info.plist is specified by this property it may of course hard-code
      all the settings instead of using the target properties.
 
  MACOSX_FRAMEWORK_INFO_PLIST
      Specify a custom Info.plist template for a Mac OS X Framework.
 
      An library target with FRAMEWORK enabled will be built as a framework
      on Mac OS X.  By default its Info.plist file is created by configuring
      a template called MacOSXFrameworkInfo.plist.in located in the
      CMAKE_MODULE_PATH.  This property specifies an alternative template
      file name which may be a full path.
 
      The following target properties may be set to specify content to be
      configured into the file:
 
        MACOSX_FRAMEWORK_ICON_FILE
        MACOSX_FRAMEWORK_IDENTIFIER
        MACOSX_FRAMEWORK_SHORT_VERSION_STRING
        MACOSX_FRAMEWORK_BUNDLE_VERSION
 
      CMake variables of the same name may be set to affect all targets in a
      directory that do not have each specific property set.  If a custom
      Info.plist is specified by this property it may of course hard-code
      all the settings instead of using the target properties.
 
  MAP_IMPORTED_CONFIG_<CONFIG>
      Map from project configuration to IMPORTED target's configuration.
 
      Set this to the list of configurations of an imported target that may
      be used for the current project's <CONFIG> configuration.  Targets
      imported from another project may not provide the same set of
      configuration names available in the current project.  Setting this
      property tells CMake what imported configurations are suitable for use
      when building the <CONFIG> configuration.  The first configuration in
      the list found to be provided by the imported target is selected.  If
      this property is set and no matching configurations are available,
      then the imported target is considered to be not found.  This property
      is ignored for non-imported targets.
 
  NO_SONAME
      Whether to set "soname" when linking a shared library or module.
 
      Enable this boolean property if a generated shared library or module
      should not have "soname" set.  Default is to set "soname" on all
      shared libraries and modules as long as the platform supports it.
      Generally, use this property only for leaf private libraries or
      plugins.  If you use it on normal shared libraries which other targets
      link against, on some platforms a linker will insert a full path to
      the library (as specified at link time) into the dynamic section of
      the dependent binary.  Therefore, once installed, dynamic loader may
      eventually fail to locate the library for the binary.
 
  OSX_ARCHITECTURES
      Target specific architectures for OS X.
 
      The OSX_ARCHITECTURES property sets the target binary architecture for
      targets on OS X.  This property is initialized by the value of the
      variable CMAKE_OSX_ARCHITECTURES if it is set when a target is
      created.  Use OSX_ARCHITECTURES_<CONFIG> to set the binary
      architectures on a per-configuration basis.  <CONFIG> is an upper-case
      name (ex: "OSX_ARCHITECTURES_DEBUG").
 
  OSX_ARCHITECTURES_<CONFIG>
      Per-configuration OS X binary architectures for a target.
 
      This property is the configuration-specific version of
      OSX_ARCHITECTURES.
 
  OUTPUT_NAME
      Output name for target files.
 
      This sets the base name for output files created for an executable or
      library target.  If not set, the logical target name is used by
      default.
 
  OUTPUT_NAME_<CONFIG>
      Per-configuration target file base name.
 
      This is the configuration-specific version of OUTPUT_NAME.
 
  PDB_NAME
      Output name for MS debug symbols .pdb file.
 
      Set the base name for debug symbols file created for an executable or
      library target.  If not set, the logical target name is used by
      default.
 
      This property is not implemented by the Visual Studio 6 generator.
 
  PDB_NAME_<CONFIG>
      Per-configuration name for MS debug symbols .pdb file.
 
      This is the configuration-specific version of PDB_NAME.
 
      This property is not implemented by the Visual Studio 6 generator.
 
  PDB_OUTPUT_DIRECTORY
      Output directory for MS debug symbols .pdb files.
 
      This property specifies the directory into which the MS debug symbols
      will be placed.  This property is initialized by the value of the
      variable CMAKE_PDB_OUTPUT_DIRECTORY if it is set when a target is
      created.
 
      This property is not implemented by the Visual Studio 6 generator.
 
  PDB_OUTPUT_DIRECTORY_<CONFIG>
      Per-configuration output directory for MS debug symbols .pdb files.
 
      This is a per-configuration version of PDB_OUTPUT_DIRECTORY, but
      multi-configuration generators (VS, Xcode) do NOT append a
      per-configuration subdirectory to the specified directory.  This
      property is initialized by the value of the variable
      CMAKE_PDB_OUTPUT_DIRECTORY_<CONFIG> if it is set when a target is
      created.
 
      This property is not implemented by the Visual Studio 6 generator.
 
  POSITION_INDEPENDENT_CODE
      Whether to create a position-independent target
 
      The POSITION_INDEPENDENT_CODE property determines whether position
      independent executables or shared libraries will be created.  This
      property is true by default for SHARED and MODULE library targets and
      false otherwise.  This property is initialized by the value of the
      variable CMAKE_POSITION_INDEPENDENT_CODE if it is set when a target is
      created.
 
  POST_INSTALL_SCRIPT
      Deprecated install support.
 
      The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
      way to specify CMake scripts to run before and after installing a
      target.  They are used only when the old INSTALL_TARGETS command is
      used to install the target.  Use the INSTALL command instead.
 
  PREFIX
      What comes before the library name.
 
      A target property that can be set to override the prefix (such as
      "lib") on a library name.
 
  PRE_INSTALL_SCRIPT
      Deprecated install support.
 
      The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
      way to specify CMake scripts to run before and after installing a
      target.  They are used only when the old INSTALL_TARGETS command is
      used to install the target.  Use the INSTALL command instead.
 
  PRIVATE_HEADER
      Specify private header files in a FRAMEWORK shared library target.
 
      Shared library targets marked with the FRAMEWORK property generate
      frameworks on OS X and normal shared libraries on other platforms.
      This property may be set to a list of header files to be placed in the
      PrivateHeaders directory inside the framework folder.  On non-Apple
      platforms these headers may be installed using the PRIVATE_HEADER
      option to the install(TARGETS) command.
 
  PROJECT_LABEL
      Change the name of a target in an IDE.
 
      Can be used to change the name of the target in an IDE like Visual
      Studio.
 
  PUBLIC_HEADER
      Specify public header files in a FRAMEWORK shared library target.
 
      Shared library targets marked with the FRAMEWORK property generate
      frameworks on OS X and normal shared libraries on other platforms.
      This property may be set to a list of header files to be placed in the
      Headers directory inside the framework folder.  On non-Apple platforms
      these headers may be installed using the PUBLIC_HEADER option to the
      install(TARGETS) command.
 
  RESOURCE
      Specify resource files in a FRAMEWORK shared library target.
 
      Shared library targets marked with the FRAMEWORK property generate
      frameworks on OS X and normal shared libraries on other platforms.
      This property may be set to a list of files to be placed in the
      Resources directory inside the framework folder.  On non-Apple
      platforms these files may be installed using the RESOURCE option to
      the install(TARGETS) command.
 
  RULE_LAUNCH_COMPILE
      Specify a launcher for compile rules.
 
      See the global property of the same name for details.  This overrides
      the global and directory property for a target.
 
  RULE_LAUNCH_CUSTOM
      Specify a launcher for custom rules.
 
      See the global property of the same name for details.  This overrides
      the global and directory property for a target.
 
  RULE_LAUNCH_LINK
      Specify a launcher for link rules.
 
      See the global property of the same name for details.  This overrides
      the global and directory property for a target.
 
  RUNTIME_OUTPUT_DIRECTORY
      Output directory in which to build RUNTIME target files.
 
      This property specifies the directory into which runtime target files
      should be built.  Multi-configuration generators (VS, Xcode) append a
      per-configuration subdirectory to the specified directory.  There are
      three kinds of target files that may be built: archive, library, and
      runtime.  Executables are always treated as runtime targets.  Static
      libraries are always treated as archive targets.  Module libraries are
      always treated as library targets.  For non-DLL platforms shared
      libraries are treated as library targets.  For DLL platforms the DLL
      part of a shared library is treated as a runtime target and the
      corresponding import library is treated as an archive target.  All
      Windows-based systems including Cygwin are DLL platforms.  This
      property is initialized by the value of the variable
      CMAKE_RUNTIME_OUTPUT_DIRECTORY if it is set when a target is created.
 
  RUNTIME_OUTPUT_DIRECTORY_<CONFIG>
      Per-configuration output directory for RUNTIME target files.
 
      This is a per-configuration version of RUNTIME_OUTPUT_DIRECTORY, but
      multi-configuration generators (VS, Xcode) do NOT append a
      per-configuration subdirectory to the specified directory.  This
      property is initialized by the value of the variable
      CMAKE_RUNTIME_OUTPUT_DIRECTORY_<CONFIG> if it is set when a target is
      created.
 
  RUNTIME_OUTPUT_NAME
      Output name for RUNTIME target files.
 
      This property specifies the base name for runtime target files.  It
      overrides OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties.  There are
      three kinds of target files that may be built: archive, library, and
      runtime.  Executables are always treated as runtime targets.  Static
      libraries are always treated as archive targets.  Module libraries are
      always treated as library targets.  For non-DLL platforms shared
      libraries are treated as library targets.  For DLL platforms the DLL
      part of a shared library is treated as a runtime target and the
      corresponding import library is treated as an archive target.  All
      Windows-based systems including Cygwin are DLL platforms.
 
  RUNTIME_OUTPUT_NAME_<CONFIG>
      Per-configuration output name for RUNTIME target files.
 
      This is the configuration-specific version of RUNTIME_OUTPUT_NAME.
 
  SKIP_BUILD_RPATH
      Should rpaths be used for the build tree.
 
      SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic
      generation of an rpath allowing the target to run from the build tree.
      This property is initialized by the value of the variable
      CMAKE_SKIP_BUILD_RPATH if it is set when a target is created.
 
  SOURCES
      Source names specified for a target.
 
      Read-only list of sources specified for a target.  The names returned
      are suitable for passing to the set_source_files_properties command.
 
  SOVERSION
      What version number is this target.
 
      For shared libraries VERSION and SOVERSION can be used to specify the
      build version and api version respectively.  When building or
      installing appropriate symlinks are created if the platform supports
      symlinks and the linker supports so-names.  If only one of both is
      specified the missing is assumed to have the same version number.
      SOVERSION is ignored if NO_SONAME property is set.  For shared
      libraries and executables on Windows the VERSION attribute is parsed
      to extract a "major.minor" version number.  These numbers are used as
      the image version of the binary.
 
  STATIC_LIBRARY_FLAGS
      Extra flags to use when linking static libraries.
 
      Extra flags to use when linking a static library.
 
  STATIC_LIBRARY_FLAGS_<CONFIG>
      Per-configuration flags for creating a static library.
 
      This is the configuration-specific version of STATIC_LIBRARY_FLAGS.
 
  SUFFIX
      What comes after the target name.
 
      A target property that can be set to override the suffix (such as
      ".so" or ".exe") on the name of a library, module or executable.
 
  TYPE
      The type of the target.
 
      This read-only property can be used to test the type of the given
      target.  It will be one of STATIC_LIBRARY, MODULE_LIBRARY,
      SHARED_LIBRARY, EXECUTABLE or one of the internal target types.
 
  VERSION
      What version number is this target.
 
      For shared libraries VERSION and SOVERSION can be used to specify the
      build version and api version respectively.  When building or
      installing appropriate symlinks are created if the platform supports
      symlinks and the linker supports so-names.  If only one of both is
      specified the missing is assumed to have the same version number.  For
      executables VERSION can be used to specify the build version.  When
      building or installing appropriate symlinks are created if the
      platform supports symlinks.  For shared libraries and executables on
      Windows the VERSION attribute is parsed to extract a "major.minor"
      version number.  These numbers are used as the image version of the
      binary.
 
  VS_DOTNET_REFERENCES
      Visual Studio managed project .NET references
 
      Adds one or more semicolon-delimited .NET references to a generated
      Visual Studio project.  For example, "System;System.Windows.Forms".
 
  VS_GLOBAL_<variable>
      Visual Studio project-specific global variable.
 
      Tell the Visual Studio generator to set the global variable
      '<variable>' to a given value in the generated Visual Studio project.
      Ignored on other generators.  Qt integration works better if
      VS_GLOBAL_QtVersion is set to the version FindQt4.cmake found.  For
      example, "4.7.3"
 
  VS_GLOBAL_KEYWORD
      Visual Studio project keyword.
 
      Sets the "keyword" attribute for a generated Visual Studio project.
      Defaults to "Win32Proj".  You may wish to override this value with
      "ManagedCProj", for example, in a Visual Studio managed C++ unit test
      project.
 
  VS_GLOBAL_PROJECT_TYPES
      Visual Studio project type(s).
 
      Can be set to one or more UUIDs recognized by Visual Studio to
      indicate the type of project.  This value is copied verbatim into the
      generated project file.  Example for a managed C++ unit testing
      project:
 
        {3AC096D0-A1C2-E12C-1390-A8335801FDAB};{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}
 
      UUIDs are semicolon-delimited.
 
  VS_KEYWORD
      Visual Studio project keyword.
 
      Can be set to change the visual studio keyword, for example Qt
      integration works better if this is set to Qt4VSv1.0.
 
  VS_SCC_AUXPATH
      Visual Studio Source Code Control Aux Path.
 
      Can be set to change the visual studio source code control auxpath
      property.
 
  VS_SCC_LOCALPATH
      Visual Studio Source Code Control Local Path.
 
      Can be set to change the visual studio source code control local path
      property.
 
  VS_SCC_PROJECTNAME
      Visual Studio Source Code Control Project.
 
      Can be set to change the visual studio source code control project
      name property.
 
  VS_SCC_PROVIDER
      Visual Studio Source Code Control Provider.
 
      Can be set to change the visual studio source code control provider
      property.
 
  VS_WINRT_EXTENSIONS
      Visual Studio project C++/CX language extensions for Windows Runtime
 
      Can be set to enable C++/CX language extensions.
 
  VS_WINRT_REFERENCES
      Visual Studio project Windows Runtime Metadata references
 
      Adds one or more semicolon-delimited WinRT references to a generated
      Visual Studio project.  For example, "Windows;Windows.UI.Core".
 
  WIN32_EXECUTABLE
      Build an executable with a WinMain entry point on windows.
 
      When this property is set to true the executable when linked on
      Windows will be created with a WinMain() entry point instead of just
      main().  This makes it a GUI executable instead of a console
      application.  See the CMAKE_MFC_FLAG variable documentation to
      configure use of MFC for WinMain executables.  This property is
      initialized by the value of the variable CMAKE_WIN32_EXECUTABLE if it
      is set when a target is created.
 
  XCODE_ATTRIBUTE_<an-attribute>
      Set Xcode target attributes directly.
 
      Tell the Xcode generator to set '<an-attribute>' to a given value in
      the generated Xcode project.  Ignored on other generators.
 
------------------------------------------------------------------------------
Properties on Tests
 
  ATTACHED_FILES
      Attach a list of files to a dashboard submission.
 
      Set this property to a list of files that will be encoded and
      submitted to the dashboard as an addition to the test result.
 
  ATTACHED_FILES_ON_FAIL
      Attach a list of files to a dashboard submission if the test fails.
 
      Same as ATTACHED_FILES, but these files will only be included if the
      test does not pass.
 
  COST
      Set this to a floating point value.  Tests in a test set will be run
      in descending order of cost.
 
      This property describes the cost of a test.  You can explicitly set
      this value; tests with higher COST values will run first.
 
  DEPENDS
      Specifies that this test should only be run after the specified list
      of tests.
 
      Set this to a list of tests that must finish before this test is run.
 
  ENVIRONMENT
      Specify environment variables that should be defined for running a
      test.
 
      If set to a list of environment variables and values of the form
      MYVAR=value those environment variables will be defined while running
      the test.  The environment is restored to its previous state after the
      test is done.
 
  FAIL_REGULAR_EXPRESSION
      If the output matches this regular expression the test will fail.
 
      If set, if the output matches one of specified regular expressions,
      the test will fail.For example: PASS_REGULAR_EXPRESSION
      "[^a-z]Error;ERROR;Failed"
 
  LABELS
      Specify a list of text labels associated with a test.
 
      The list is reported in dashboard submissions.
 
  MEASUREMENT
      Specify a CDASH measurement and value to be reported for a test.
 
      If set to a name then that name will be reported to CDASH as a named
      measurement with a value of 1.  You may also specify a value by
      setting MEASUREMENT to "measurement=value".
 
  PASS_REGULAR_EXPRESSION
      The output must match this regular expression for the test to pass.
 
      If set, the test output will be checked against the specified regular
      expressions and at least one of the regular expressions has to match,
      otherwise the test will fail.
 
  PROCESSORS
      How many process slots this test requires
 
      Denotes the number of processors that this test will require.  This is
      typically used for MPI tests, and should be used in conjunction with
      the ctest_test PARALLEL_LEVEL option.
 
  REQUIRED_FILES
      List of files required to run the test.
 
      If set to a list of files, the test will not be run unless all of the
      files exist.
 
  RESOURCE_LOCK
      Specify a list of resources that are locked by this test.
 
      If multiple tests specify the same resource lock, they are guaranteed
      not to run concurrently.
 
  RUN_SERIAL
      Do not run this test in parallel with any other test.
 
      Use this option in conjunction with the ctest_test PARALLEL_LEVEL
      option to specify that this test should not be run in parallel with
      any other tests.
 
  TIMEOUT
      How many seconds to allow for this test.
 
      This property if set will limit a test to not take more than the
      specified number of seconds to run.  If it exceeds that the test
      process will be killed and ctest will move to the next test.  This
      setting takes precedence over CTEST_TESTING_TIMEOUT.
 
  WILL_FAIL
      If set to true, this will invert the pass/fail flag of the test.
 
      This property can be used for tests that are expected to fail and
      return a non zero return code.
 
  WORKING_DIRECTORY
      The directory from which the test executable will be called.
 
      If this is not set it is called from the directory the test executable
      is located in.

      A property on a source file that indicates if the source file
      represents a class that is abstract.  This only makes sense for
      languages that have a notion of an abstract class and it is only used
      by some tools that wrap classes into other languages.
 
  COMPILE_DEFINITIONS
      Preprocessor definitions for compiling a source file.
 
      The COMPILE_DEFINITIONS property may be set to a semicolon-separated
      list of preprocessor definitions using the syntax VAR or VAR=value.
      Function-style definitions are not supported.  CMake will
      automatically escape the value correctly for the native build system
      (note that CMake language syntax may require escapes to specify some
      values).  This property may be set on a per-configuration basis using
      the name COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case
      name (ex.  "COMPILE_DEFINITIONS_DEBUG").
 
      CMake will automatically drop some definitions that are not supported
      by the native build tool.  The VS6 IDE does not support definition
      values with spaces (but NMake does).  Xcode does not support
      per-configuration definitions on source files.
 
      Disclaimer: Most native build tools have poor support for escaping
      certain values.  CMake has work-arounds for many cases but some values
      may just not be possible to pass correctly.  If a value does not seem
      to be escaped correctly, do not attempt to work-around the problem by
      adding escape sequences to the value.  Your work-around may break in a
      future version of CMake that has improved escape support.  Instead
      consider defining the macro in a (configured) header file.  Then
      report the limitation.  Known limitations include:
 
        #          - broken almost everywhere
        ;          - broken in VS IDE and Borland Makefiles
        ,          - broken in VS IDE
        %          - broken in some cases in NMake
        & |        - broken in some cases on MinGW
        ^ < > \"  - broken in most Make tools on Windows
 
      CMake does not reject these values outright because they do work in
      some cases.  Use with caution.
 
  COMPILE_DEFINITIONS_<CONFIG>
      Per-configuration preprocessor definitions on a source file.
 
      This is the configuration-specific version of COMPILE_DEFINITIONS.
      Note that Xcode does not support per-configuration source file flags
      so this property will be ignored by the Xcode generator.
 
  COMPILE_FLAGS
      Additional flags to be added when compiling this source file.
 
      These flags will be added to the list of compile flags when this
      source file builds.  Use COMPILE_DEFINITIONS to pass additional
      preprocessor definitions.
 
  EXTERNAL_OBJECT
      If set to true then this is an object file.
 
      If this property is set to true then the source file is really an
      object file and should not be compiled.  It will still be linked into
      the target though.
 
  Fortran_FORMAT
      Set to FIXED or FREE to indicate the Fortran source layout.
 
      This property tells CMake whether a given Fortran source file uses
      fixed-format or free-format.  CMake will pass the corresponding format
      flag to the compiler.  Consider using the target-wide Fortran_FORMAT
      property if all source files in a target share the same format.
 
  GENERATED
      Is this source file generated as part of the build process.
 
      If a source file is generated by the build process CMake will handle
      it differently in terms of dependency checking etc.  Otherwise having
      a non-existent source file could create problems.
 
  HEADER_FILE_ONLY
      Is this source file only a header file.
 
      A property on a source file that indicates if the source file is a
      header file with no associated implementation.  This is set
      automatically based on the file extension and is used by CMake to
      determine is certain dependency information should be computed.
 
  KEEP_EXTENSION
      Make the output file have the same extension as the source file.
 
      If this property is set then the file extension of the output file
      will be the same as that of the source file.  Normally the output file
      extension is computed based on the language of the source file, for
      example .cxx will go to a .o extension.
 
  LABELS
      Specify a list of text labels associated with a source file.
 
      This property has meaning only when the source file is listed in a
      target whose LABELS property is also set.  No other semantics are
      currently specified.
 
  LANGUAGE
      What programming language is the file.
 
      A property that can be set to indicate what programming language the
      source file is.  If it is not set the language is determined based on
      the file extension.  Typical values are CXX C etc.  Setting this
      property for a file means this file will be compiled.  Do not set this
      for header or files that should not be compiled.
 
  LOCATION
      The full path to a source file.
 
      A read only property on a SOURCE FILE that contains the full path to
      the source file.
 
  MACOSX_PACKAGE_LOCATION
      Place a source file inside a Mac OS X bundle, CFBundle, or framework.
 
      Executable targets with the MACOSX_BUNDLE property set are built as
      Mac OS X application bundles on Apple platforms.  Shared library
      targets with the FRAMEWORK property set are built as Mac OS X
      frameworks on Apple platforms.  Module library targets with the BUNDLE
      property set are built as Mac OS X CFBundle bundles on Apple
      platforms.  Source files listed in the target with this property set
      will be copied to a directory inside the bundle or framework content
      folder specified by the property value.  For bundles the content
      folder is "<name>.app/Contents".  For frameworks the content folder is
      "<name>.framework/Versions/<version>".  For cfbundles the content
      folder is "<name>.bundle/Contents" (unless the extension is changed).
      See the PUBLIC_HEADER, PRIVATE_HEADER, and RESOURCE target properties
      for specifying files meant for Headers, PrivateHeaders, or Resources
      directories.
 
  OBJECT_DEPENDS
      Additional files on which a compiled object file depends.
 
      Specifies a semicolon-separated list of full-paths to files on which
      any object files compiled from this source file depend.  An object
      file will be recompiled if any of the named files is newer than it.
 
      This property need not be used to specify the dependency of a source
      file on a generated header file that it includes.  Although the
      property was originally introduced for this purpose, it is no longer
      necessary.  If the generated header file is created by a custom
      command in the same target as the source file, the automatic
      dependency scanning process will recognize the dependency.  If the
      generated header file is created by another target, an inter-target
      dependency should be created with the add_dependencies command (if one
      does not already exist due to linking relationships).
 
  OBJECT_OUTPUTS
      Additional outputs for a Makefile rule.
 
      Additional outputs created by compilation of this source file.  If any
      of these outputs is missing the object will be recompiled.  This is
      supported only on Makefile generators and will be ignored on other
      generators.
 
  SYMBOLIC
      Is this just a name for a rule.
 
      If SYMBOLIC (boolean) is set to true the build system will be informed
      that the source file is not actually created on disk but instead used
      as a symbolic name for a build rule.
 
  WRAP_EXCLUDE
      Exclude this source file from any code wrapping techniques.
 
      Some packages can wrap source files into alternate languages to
      provide additional functionality.  For example, C++ code can be
      wrapped into Java or Python etc using SWIG etc.  If WRAP_EXCLUDE is
      set to true (1 etc) that indicates then this source file should not be
      wrapped.
 
------------------------------------------------------------------------------
Properties on Cache Entries
 
  ADVANCED
      True if entry should be hidden by default in GUIs.
 
      This is a boolean value indicating whether the entry is considered
      interesting only for advanced configuration.  The mark_as_advanced()
      command modifies this property.
 
  HELPSTRING
      Help associated with entry in GUIs.
 
      This string summarizes the purpose of an entry to help users set it
      through a CMake GUI.
 
  MODIFIED
      Internal management property.  Do not set or get.
 
      This is an internal cache entry property managed by CMake to track
      interactive user modification of entries.  Ignore it.
 
  STRINGS
      Enumerate possible STRING entry values for GUI selection.
 
      For cache entries with type STRING, this enumerates a set of values.
      CMake GUIs may use this to provide a selection widget instead of a
      generic string entry field.  This is for convenience only.  CMake does
      not enforce that the value matches one of those listed.
 
  TYPE
      Widget type for entry in GUIs.
 
      Cache entry values are always strings, but CMake GUIs present widgets
      to help users set values.  The GUIs use this property as a hint to
      determine the widget type.  Valid TYPE values are:
 
        BOOL          = Boolean ON/OFF value.
        PATH          = Path to a directory.
        FILEPATH      = Path to a file.
        STRING        = Generic string value.
        INTERNAL      = Do not present in GUI at all.
        STATIC        = Value managed by CMake, do not change.
        UNINITIALIZED = Type not yet specified.
 
      Generally the TYPE of a cache entry should be set by the command which
      creates it (set, option, find_library, etc.).
 
  VALUE
      Value of a cache entry.
 
      This property maps to the actual value of a cache entry.  Setting this
      property always sets the value without checking, so use with care.
 
------------------------------------------------------------------------------
Compatibility Commands
 
  CMake Compatibility Listfile Commands - Obsolete commands supported by CMake for compatibility.
 
This is the documentation for now obsolete listfile commands from previous
CMake versions, which are still supported for compatibility reasons.  You
should instead use the newer, faster and shinier new commands.  ;-)
 
  build_name
      Deprecated.  Use ${CMAKE_SYSTEM} and ${CMAKE_CXX_COMPILER} instead.
 
        build_name(variable)
 
      Sets the specified variable to a string representing the platform and
      compiler settings.  These values are now available through the
      CMAKE_SYSTEM and CMAKE_CXX_COMPILER variables.
 
  exec_program
      Deprecated.  Use the execute_process() command instead.
 
      Run an executable program during the processing of the CMakeList.txt
      file.
 
        exec_program(Executable [directory in which to run]
                      [ARGS <arguments to executable>]
                      [OUTPUT_VARIABLE <var>]
                      [RETURN_VALUE <var>])
 
      The executable is run in the optionally specified directory.  The
      executable can include arguments if it is double quoted, but it is
      better to use the optional ARGS argument to specify arguments to the
      program.  This is because cmake will then be able to escape spaces in
      the executable path.  An optional argument OUTPUT_VARIABLE specifies a
      variable in which to store the output.  To capture the return value of
      the execution, provide a RETURN_VALUE.  If OUTPUT_VARIABLE is
      specified, then no output will go to the stdout/stderr of the console
      running cmake.
 
 
  export_library_dependencies
      Deprecated.  Use INSTALL(EXPORT) or EXPORT command.
 
      This command generates an old-style library dependencies file.
      Projects requiring CMake 2.6 or later should not use the command.  Use
      instead the install(EXPORT) command to help export targets from an
      installation tree and the export() command to export targets from a
      build tree.
 
      The old-style library dependencies file does not take into account
      per-configuration names of libraries or the LINK_INTERFACE_LIBRARIES
      target property.
 
        export_library_dependencies(<file> [APPEND])
 
      Create a file named <file> that can be included into a CMake listfile
      with the INCLUDE command.  The file will contain a number of SET
      commands that will set all the variables needed for library dependency
      information.  This should be the last command in the top level
      CMakeLists.txt file of the project.  If the APPEND option is
      specified, the SET commands will be appended to the given file instead
      of replacing it.
 
  install_files
      Deprecated.  Use the install(FILES ) command instead.
 
      This command has been superceded by the install command.  It is
      provided for compatibility with older CMake code.  The FILES form is
      directly replaced by the FILES form of the install command.  The
      regexp form can be expressed more clearly using the GLOB form of the
      file command.
 
        install_files(<dir> extension file file ...)
 
      Create rules to install the listed files with the given extension into
      the given directory.  Only files existing in the current source tree
      or its corresponding location in the binary tree may be listed.  If a
      file specified already has an extension, that extension will be
      removed first.  This is useful for providing lists of source files
      such as foo.cxx when you want the corresponding foo.h to be installed.
      A typical extension is '.h'.
 
        install_files(<dir> regexp)
 
      Any files in the current source directory that match the regular
      expression will be installed.
 
        install_files(<dir> FILES file file ...)
 
      Any files listed after the FILES keyword will be installed explicitly
      from the names given.  Full paths are allowed in this form.
 
      The directory <dir> is relative to the installation prefix, which is
      stored in the variable CMAKE_INSTALL_PREFIX.
 
  install_programs
      Deprecated.  Use the install(PROGRAMS ) command instead.
 
      This command has been superceded by the install command.  It is
      provided for compatibility with older CMake code.  The FILES form is
      directly replaced by the PROGRAMS form of the INSTALL command.  The
      regexp form can be expressed more clearly using the GLOB form of the
      FILE command.
 
        install_programs(<dir> file1 file2 [file3 ...])
        install_programs(<dir> FILES file1 [file2 ...])
 
      Create rules to install the listed programs into the given directory.
      Use the FILES argument to guarantee that the file list version of the
      command will be used even when there is only one argument.
 
        install_programs(<dir> regexp)
 
      In the second form any program in the current source directory that
      matches the regular expression will be installed.
 
      This command is intended to install programs that are not built by
      cmake, such as shell scripts.  See the TARGETS form of the INSTALL
      command to create installation rules for targets built by cmake.
 
      The directory <dir> is relative to the installation prefix, which is
      stored in the variable CMAKE_INSTALL_PREFIX.
 
  install_targets
      Deprecated.  Use the install(TARGETS ) command instead.
 
      This command has been superceded by the install command.  It is
      provided for compatibility with older CMake code.
 
        install_targets(<dir> [RUNTIME_DIRECTORY dir] target target)
 
      Create rules to install the listed targets into the given directory.
      The directory <dir> is relative to the installation prefix, which is
      stored in the variable CMAKE_INSTALL_PREFIX.  If RUNTIME_DIRECTORY is
      specified, then on systems with special runtime files (Windows DLL),
      the files will be copied to that directory.
 
  link_libraries
      Deprecated.  Use the target_link_libraries() command instead.
 
      Link libraries to all targets added later.
 
        link_libraries(library1 <debug | optimized> library2 ...)
 
      Specify a list of libraries to be linked into any following targets
      (typically added with the add_executable or add_library calls).  This
      command is passed down to all subdirectories.  The debug and optimized
      strings may be used to indicate that the next library listed is to be
      used only for that specific type of build.
 
  make_directory
      Deprecated.  Use the file(MAKE_DIRECTORY ) command instead.
 
        make_directory(directory)
 
      Creates the specified directory.  Full paths should be given.  Any
      parent directories that do not exist will also be created.  Use with
      care.
 
  output_required_files
      Deprecated.  Approximate C preprocessor dependency scanning.
 
      This command exists only because ancient CMake versions provided it.
      CMake handles preprocessor dependency scanning automatically using a
      more advanced scanner.
 
        output_required_files(srcfile outputfile)
 
      Outputs a list of all the source files that are required by the
      specified srcfile.  This list is written into outputfile.  This is
      similar to writing out the dependencies for srcfile except that it
      jumps from .h files into .cxx, .c and .cpp files if possible.
 
  remove
      Deprecated.  Use the list(REMOVE_ITEM ) command instead.
 
        remove(VAR VALUE VALUE ...)
 
      Removes VALUE from the variable VAR.  This is typically used to remove
      entries from a vector (e.g.  semicolon separated list).  VALUE is
      expanded.
 
  subdir_depends
      Deprecated.  Does nothing.
 
        subdir_depends(subdir dep1 dep2 ...)
 
      Does not do anything.  This command used to help projects order
      parallel builds correctly.  This functionality is now automatic.
 
  subdirs
      Deprecated.  Use the add_subdirectory() command instead.
 
      Add a list of subdirectories to the build.
 
        subdirs(dir1 dir2 ...[EXCLUDE_FROM_ALL exclude_dir1 exclude_dir2 ...]
                [PREORDER] )
 
      Add a list of subdirectories to the build.  The add_subdirectory
      command should be used instead of subdirs although subdirs will still
      work.  This will cause any CMakeLists.txt files in the sub directories
      to be processed by CMake.  Any directories after the PREORDER flag are
      traversed first by makefile builds, the PREORDER flag has no effect on
      IDE projects.  Any directories after the EXCLUDE_FROM_ALL marker will
      not be included in the top level makefile or project file.  This is
      useful for having CMake create makefiles or projects for a set of
      examples in a project.  You would want CMake to generate makefiles or
      project files for all the examples at the same time, but you would not
      want them to show up in the top level project or be built each time
      make is run from the top.
 
  use_mangled_mesa
      Copy mesa headers for use in combination with system GL.
 
        use_mangled_mesa(PATH_TO_MESA OUTPUT_DIRECTORY)
 
      The path to mesa includes, should contain gl_mangle.h.  The mesa
      headers are copied to the specified output directory.  This allows
      mangled mesa headers to override other GL headers by being added to
      the include directory path earlier.
 
  utility_source
      Specify the source tree of a third-party utility.
 
        utility_source(cache_entry executable_name
                        path_to_source [file1 file2 ...])
 
      When a third-party utility's source is included in the distribution,
      this command specifies its location and name.  The cache entry will
      not be set unless the path_to_source and all listed files exist.  It
      is assumed that the source tree of the utility will have been built
      before it is needed.
 
      When cross compiling CMake will print a warning if a utility_source()
      command is executed, because in many cases it is used to build an
      executable which is executed later on.  This doesn't work when cross
      compiling, since the executable can run only on their target platform.
      So in this case the cache entry has to be adjusted manually so it
      points to an executable which is runnable on the build host.
 
  variable_requires
      Deprecated.  Use the if() command instead.
 
      Assert satisfaction of an option's required variables.
 
        variable_requires(TEST_VARIABLE RESULT_VARIABLE
                          REQUIRED_VARIABLE1
                          REQUIRED_VARIABLE2 ...)
 
      The first argument (TEST_VARIABLE) is the name of the variable to be
      tested, if that variable is false nothing else is done.  If
      TEST_VARIABLE is true, then the next argument (RESULT_VARIABLE) is a
      variable that is set to true if all the required variables are set.
      The rest of the arguments are variables that must be true or not set
      to NOTFOUND to avoid an error.  If any are not true, an error is
      reported.
 
  write_file
      Deprecated.  Use the file(WRITE ) command instead.
 
        write_file(filename "message to write"... [APPEND])
 
      The first argument is the file name, the rest of the arguments are
      messages to write.  If the argument APPEND is specified, then the
      message will be appended.
 
      NOTE 1: file(WRITE ...  and file(APPEND ...  do exactly the same as
      this one but add some more functionality.
 
      NOTE 2: When using write_file the produced file cannot be used as an
      input to CMake (CONFIGURE_FILE, source file ...) because it will lead
      to an infinite loop.  Use configure_file if you want to generate input
      files to CMake.
 
------------------------------------------------------------------------------
Standard CMake Modules
 
The following modules are provided with CMake.  They can be used with
INCLUDE(ModuleName).
 
  CMake Modules - Modules coming with CMake, the Cross-Platform Makefile Generator.
 
This is the documentation for the modules and scripts coming with CMake.
Using these modules you can check the computer system for installed software
packages, features of the compiler and the existance of headers to name just
a few.
 
  AddFileDependencies
      ADD_FILE_DEPENDENCIES(source_file depend_files...)
 
      Adds the given files as dependencies to source_file
 
 
  BundleUtilities
      Functions to help assemble a standalone bundle application.
 
      A collection of CMake utility functions useful for dealing with .app
      bundles on the Mac and bundle-like directories on any OS.
 
      The following functions are provided by this module:
 
          fixup_bundle
          copy_and_fixup_bundle
          verify_app
          get_bundle_main_executable
          get_dotapp_dir
          get_bundle_and_executable
          get_bundle_all_executables
          get_item_key
          clear_bundle_keys
          set_bundle_key_values
          get_bundle_keys
          copy_resolved_item_into_bundle
          copy_resolved_framework_into_bundle
          fixup_bundle_item
          verify_bundle_prerequisites
          verify_bundle_symlinks
 
      Requires CMake 2.6 or greater because it uses function, break and
      PARENT_SCOPE.  Also depends on GetPrerequisites.cmake.
 
        FIXUP_BUNDLE(<app> <libs> <dirs>)
 
      Fix up a bundle in-place and make it standalone, such that it can be
      drag-n-drop copied to another machine and run on that machine as long
      as all of the system libraries are compatible.
 
      If you pass plugins to fixup_bundle as the libs parameter, you should
      install them or copy them into the bundle before calling fixup_bundle.
      The "libs" parameter is a list of libraries that must be fixed up, but
      that cannot be determined by otool output analysis.  (i.e., plugins)
 
      Gather all the keys for all the executables and libraries in a bundle,
      and then, for each key, copy each prerequisite into the bundle.  Then
      fix each one up according to its own list of prerequisites.
 
      Then clear all the keys and call verify_app on the final bundle to
      ensure that it is truly standalone.
 
        COPY_AND_FIXUP_BUNDLE(<src> <dst> <libs> <dirs>)
 
      Makes a copy of the bundle <src> at location <dst> and then fixes up
      the new copied bundle in-place at <dst>...
 
        VERIFY_APP(<app>)
 
      Verifies that an application <app> appears valid based on running
      analysis tools on it.  Calls "message(FATAL_ERROR" if the application
      is not verified.
 
        GET_BUNDLE_MAIN_EXECUTABLE(<bundle> <result_var>)
 
      The result will be the full path name of the bundle's main executable
      file or an "error:" prefixed string if it could not be determined.
 
        GET_DOTAPP_DIR(<exe> <dotapp_dir_var>)
 
      Returns the nearest parent dir whose name ends with ".app" given the
      full path to an executable.  If there is no such parent dir, then
      simply return the dir containing the executable.
 
      The returned directory may or may not exist.
 
        GET_BUNDLE_AND_EXECUTABLE(<app> <bundle_var> <executable_var> <valid_var>)
 
      Takes either a ".app" directory name or the name of an executable
      nested inside a ".app" directory and returns the path to the ".app"
      directory in <bundle_var> and the path to its main executable in
      <executable_var>
 
        GET_BUNDLE_ALL_EXECUTABLES(<bundle> <exes_var>)
 
      Scans the given bundle recursively for all executable files and
      accumulates them into a variable.
 
        GET_ITEM_KEY(<item> <key_var>)
 
      Given a file (item) name, generate a key that should be unique
      considering the set of libraries that need copying or fixing up to
      make a bundle standalone.  This is essentially the file name including
      extension with "." replaced by "_"
 
      This key is used as a prefix for CMake variables so that we can
      associate a set of variables with a given item based on its key.
 
        CLEAR_BUNDLE_KEYS(<keys_var>)
 
      Loop over the list of keys, clearing all the variables associated with
      each key.  After the loop, clear the list of keys itself.
 
      Caller of get_bundle_keys should call clear_bundle_keys when done with
      list of keys.
 
        SET_BUNDLE_KEY_VALUES(<keys_var> <context> <item> <exepath> <dirs>
                              <copyflag>)
 
      Add a key to the list (if necessary) for the given item.  If added,
      also set all the variables associated with that key.
 
        GET_BUNDLE_KEYS(<app> <libs> <dirs> <keys_var>)
 
      Loop over all the executable and library files within the bundle (and
      given as extra <libs>) and accumulate a list of keys representing
      them.  Set values associated with each key such that we can loop over
      all of them and copy prerequisite libs into the bundle and then do
      appropriate install_name_tool fixups.
 
        COPY_RESOLVED_ITEM_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)
 
      Copy a resolved item into the bundle if necessary.  Copy is not
      necessary if the resolved_item is "the same as" the
      resolved_embedded_item.
 
        COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)
 
      Copy a resolved framework into the bundle if necessary.  Copy is not
      necessary if the resolved_item is "the same as" the
      resolved_embedded_item.
 
      By default, BU_COPY_FULL_FRAMEWORK_CONTENTS is not set.  If you want
      full frameworks embedded in your bundles, set
      BU_COPY_FULL_FRAMEWORK_CONTENTS to ON before calling fixup_bundle.  By
      default, COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE copies the framework
      dylib itself plus the framework Resources directory.
 
        FIXUP_BUNDLE_ITEM(<resolved_embedded_item> <exepath> <dirs>)
 
      Get the direct/non-system prerequisites of the resolved embedded item.
      For each prerequisite, change the way it is referenced to the value of
      the _EMBEDDED_ITEM keyed variable for that prerequisite.  (Most likely
      changing to an "@executable_path" style reference.)
 
      This function requires that the resolved_embedded_item be "inside" the
      bundle already.  In other words, if you pass plugins to fixup_bundle
      as the libs parameter, you should install them or copy them into the
      bundle before calling fixup_bundle.  The "libs" parameter is a list of
      libraries that must be fixed up, but that cannot be determined by
      otool output analysis.  (i.e., plugins)
 
      Also, change the id of the item being fixed up to its own
      _EMBEDDED_ITEM value.
 
      Accumulate changes in a local variable and make *one* call to
      install_name_tool at the end of the function with all the changes at
      once.
 
      If the BU_CHMOD_BUNDLE_ITEMS variable is set then bundle items will be
      marked writable before install_name_tool tries to change them.
 
        VERIFY_BUNDLE_PREREQUISITES(<bundle> <result_var> <info_var>)
 
      Verifies that the sum of all prerequisites of all files inside the
      bundle are contained within the bundle or are "system" libraries,
      presumed to exist everywhere.
 
        VERIFY_BUNDLE_SYMLINKS(<bundle> <result_var> <info_var>)
 
      Verifies that any symlinks found in the bundle point to other files
      that are already also in the bundle...  Anything that points to an
      external file causes this function to fail the verification.
 
  CMakeAddFortranSubdirectory
      Use MinGW gfortran from VS if a fortran compiler is not found.
 
      The 'add_fortran_subdirectory' function adds a subdirectory to a
      project that contains a fortran only sub-project.  The module will
      check the current compiler and see if it can support fortran.  If no
      fortran compiler is found and the compiler is MSVC, then this module
      will find the MinGW gfortran.  It will then use an external project to
      build with the MinGW tools.  It will also create imported targets for
      the libraries created.  This will only work if the fortran code is
      built into a dll, so BUILD_SHARED_LIBS is turned on in the project.
      In addition the CMAKE_GNUtoMS option is set to on, so that the MS .lib
      files are created.  Usage is as follows:
 
        cmake_add_fortran_subdirectory(
          <subdir>                # name of subdirectory
          PROJECT <project_name>  # project name in subdir top CMakeLists.txt
          ARCHIVE_DIR <dir>      # dir where project places .lib files
          RUNTIME_DIR <dir>      # dir where project places .dll files
          LIBRARIES <lib>...      # names of library targets to import
          LINK_LIBRARIES          # link interface libraries for LIBRARIES
          [LINK_LIBS <lib> <dep>...]...
          CMAKE_COMMAND_LINE ...  # extra command line flags to pass to cmake
          NO_EXTERNAL_INSTALL    # skip installation of external project
          )
 
      Relative paths in ARCHIVE_DIR and RUNTIME_DIR are interpreted with
      respect to the build directory corresponding to the source directory
      in which the function is invoked.
 
      Limitations:
 
      NO_EXTERNAL_INSTALL is required for forward compatibility with a
      future version that supports installation of the external project
      binaries during "make install".
 
  CMakeBackwardCompatibilityCXX
      define a bunch of backwards compatibility variables
 
        CMAKE_ANSI_CXXFLAGS - flag for ansi c++
        CMAKE_HAS_ANSI_STRING_STREAM - has <strstream>
        include(TestForANSIStreamHeaders)
        include(CheckIncludeFileCXX)
        include(TestForSTDNamespace)
        include(TestForANSIForScope)
 
 
  CMakeDependentOption
      Macro to provide an option dependent on other options.
 
      This macro presents an option to the user only if a set of other
      conditions are true.  When the option is not presented a default value
      is used, but any value set by the user is preserved for when the
      option is presented again.  Example invocation:
 
        CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON
                                "USE_BAR;NOT USE_ZOT" OFF)
 
      If USE_BAR is true and USE_ZOT is false, this provides an option
      called USE_FOO that defaults to ON.  Otherwise, it sets USE_FOO to
      OFF.  If the status of USE_BAR or USE_ZOT ever changes, any value for
      the USE_FOO option is saved so that when the option is re-enabled it
      retains its old value.
 
  CMakeDetermineVSServicePack
      Includes a public function for assisting users in trying to determine
      the
 
      Visual Studio service pack in use.
 
      Sets the passed in variable to one of the following values or an empty
      string if unknown.
 
          vc80
          vc80sp1
          vc90
          vc90sp1
          vc100
          vc100sp1
          vc110
 
     
 
      Usage: ===========================
 
          if(MSVC)
              include(CMakeDetermineVSServicePack)
              DetermineVSServicePack( my_service_pack )
 
     
 
              if( my_service_pack )
                  message(STATUS "Detected: ${my_service_pack}")
              endif()

  CMakeExpandImportedTargets
       
 
      CMAKE_EXPAND_IMPORTED_TARGETS(<var> LIBRARIES lib1 lib2...libN
 
                                            [CONFIGURATION <config>] )
 
     
 
      CMAKE_EXPAND_IMPORTED_TARGETS() takes a list of libraries and replaces
      all imported targets contained in this list with their actual file
      paths of the referenced libraries on disk, including the libraries
      from their link interfaces.  If a CONFIGURATION is given, it uses the
      respective configuration of the imported targets if it exists.  If no
      CONFIGURATION is given, it uses the first configuration from
      ${CMAKE_CONFIGURATION_TYPES} if set, otherwise ${CMAKE_BUILD_TYPE}.
      This macro is used by all Check*.cmake files which use try_compile()
      or try_run() and support CMAKE_REQUIRED_LIBRARIES , so that these
      checks support imported targets in CMAKE_REQUIRED_LIBRARIES:
 
          cmake_expand_imported_targets(expandedLibs LIBRARIES ${CMAKE_REQUIRED_LIBRARIES}
                                                      CONFIGURATION "${CMAKE_TRY_COMPILE_CONFIGURATION}" )
 
 
  CMakeFindFrameworks
      helper module to find OSX frameworks
 
  CMakeFindPackageMode
       
 
      This file is executed by cmake when invoked with --find-package.  It
      expects that the following variables are set using -D:
 
          NAME = name of the package
          COMPILER_ID = the CMake compiler ID for which the result is, i.e. GNU/Intel/Clang/MSVC, etc.
          LANGUAGE = language for which the result will be used, i.e. C/CXX/Fortan/ASM
          MODE = EXIST : only check for existance of the given package
                COMPILE : print the flags needed for compiling an object file which uses the given package
                LINK : print the flags needed for linking when using the given package
          QUIET = if TRUE, don't print anything
 
 
  CMakeForceCompiler
       
 
      This module defines macros intended for use by cross-compiling
      toolchain files when CMake is not able to automatically detect the
      compiler identification.
 
      Macro CMAKE_FORCE_C_COMPILER has the following signature:
 
          CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>)
 
      It sets CMAKE_C_COMPILER to the given compiler and the cmake internal
      variable CMAKE_C_COMPILER_ID to the given compiler-id.  It also
      bypasses the check for working compiler and basic compiler information
      tests.
 
      Macro CMAKE_FORCE_CXX_COMPILER has the following signature:
 
          CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>)
 
      It sets CMAKE_CXX_COMPILER to the given compiler and the cmake
      internal variable CMAKE_CXX_COMPILER_ID to the given compiler-id.  It
      also bypasses the check for working compiler and basic compiler
      information tests.
 
      Macro CMAKE_FORCE_Fortran_COMPILER has the following signature:
 
          CMAKE_FORCE_Fortran_COMPILER(<compiler> <compiler-id>)
 
      It sets CMAKE_Fortran_COMPILER to the given compiler and the cmake
      internal variable CMAKE_Fortran_COMPILER_ID to the given compiler-id.
      It also bypasses the check for working compiler and basic compiler
      information tests.
 
      So a simple toolchain file could look like this:
 
          include (CMakeForceCompiler)
          set(CMAKE_SYSTEM_NAME Generic)
          CMAKE_FORCE_C_COMPILER  (chc12 MetrowerksHicross)
          CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross)
 
 
  CMakePackageConfigHelpers
      CONFIGURE_PACKAGE_CONFIG_FILE(), WRITE_BASIC_PACKAGE_VERSION_FILE()
 
     
 
          CONFIGURE_PACKAGE_CONFIG_FILE(<input> <output> INSTALL_DESTINATION <path>
                                                          [PATH_VARS <var1> <var2> ... <varN>]
                                                          [NO_SET_AND_CHECK_MACRO]
                                                          [NO_CHECK_REQUIRED_COMPONENTS_MACRO])
 
     
 
      CONFIGURE_PACKAGE_CONFIG_FILE() should be used instead of the plain
      configure_file() command when creating the <Name>Config.cmake or
      <Name>-config.cmake file for installing a project or library.  It
      helps making the resulting package relocatable by avoiding hardcoded
      paths in the installed Config.cmake file.
 
      In a FooConfig.cmake file there may be code like this to make the
      install destinations know to the using project:
 
          set(FOO_INCLUDE_DIR  "@CMAKE_INSTALL_FULL_INCLUDEDIR@" )
          set(FOO_DATA_DIR  "@CMAKE_INSTALL_PREFIX@/@RELATIVE_DATA_INSTALL_DIR@" )
          set(FOO_ICONS_DIR  "@CMAKE_INSTALL_PREFIX@/share/icons" )
          ...logic to determine installedPrefix from the own location...
          set(FOO_CONFIG_DIR  "${installedPrefix}/@CONFIG_INSTALL_DIR@" )
 
      All 4 options shown above are not sufficient, since the first 3
      hardcode the absolute directory locations, and the 4th case works only
      if the logic to determine the installedPrefix is correct, and if
      CONFIG_INSTALL_DIR contains a relative path, which in general cannot
      be guaranteed.  This has the effect that the resulting FooConfig.cmake
      file would work poorly under Windows and OSX, where users are used to
      choose the install location of a binary package at install time,
      independent from how CMAKE_INSTALL_PREFIX was set at build/cmake time.
 
      Using CONFIGURE_PACKAGE_CONFIG_FILE() helps.  If used correctly, it
      makes the resulting FooConfig.cmake file relocatable.  Usage:
 
          1. write a FooConfig.cmake.in file as you are used to
          2. insert a line containing only the string "@PACKAGE_INIT@"
          3. instead of set(FOO_DIR "@SOME_INSTALL_DIR@"), use set(FOO_DIR "@PACKAGE_SOME_INSTALL_DIR@")
            (this must be after the @PACKAGE_INIT@ line)
          4. instead of using the normal configure_file(), use CONFIGURE_PACKAGE_CONFIG_FILE()
 
     
 
      The <input> and <output> arguments are the input and output file, the
      same way as in configure_file().
 
      The <path> given to INSTALL_DESTINATION must be the destination where
      the FooConfig.cmake file will be installed to.  This can either be a
      relative or absolute path, both work.
 
      The variables <var1> to <varN> given as PATH_VARS are the variables
      which contain install destinations.  For each of them the macro will
      create a helper variable PACKAGE_<var...>.  These helper variables
      must be used in the FooConfig.cmake.in file for setting the installed
      location.  They are calculated by CONFIGURE_PACKAGE_CONFIG_FILE() so
      that they are always relative to the installed location of the
      package.  This works both for relative and also for absolute
      locations.  For absolute locations it works only if the absolute
      location is a subdirectory of CMAKE_INSTALL_PREFIX.
 
      By default configure_package_config_file() also generates two helper
      macros, set_and_check() and check_required_components() into the
      FooConfig.cmake file.
 
      set_and_check() should be used instead of the normal set() command for
      setting directories and file locations.  Additionally to setting the
      variable it also checks that the referenced file or directory actually
      exists and fails with a FATAL_ERROR otherwise.  This makes sure that
      the created FooConfig.cmake file does not contain wrong references.
      When using the NO_SET_AND_CHECK_MACRO, this macro is not generated
      into the FooConfig.cmake file.
 
      check_required_components(<package_name>) should be called at the end
      of the FooConfig.cmake file if the package supports components.  This
      macro checks whether all requested, non-optional components have been
      found, and if this is not the case, sets the Foo_FOUND variable to
      FALSE, so that the package is considered to be not found.  It does
      that by testing the Foo_<Component>_FOUND variables for all requested
      required components.  When using the NO_CHECK_REQUIRED_COMPONENTS
      option, this macro is not generated into the FooConfig.cmake file.
 
      For an example see below the documentation for
      WRITE_BASIC_PACKAGE_VERSION_FILE().
 
     
 
        WRITE_BASIC_PACKAGE_VERSION_FILE( filename VERSION major.minor.patch COMPATIBILITY (AnyNewerVersion|SameMajorVersion|ExactVersion) )
 
     
 
      Writes a file for use as <package>ConfigVersion.cmake file to
      <filename>.  See the documentation of find_package() for details on
      this.
 
          filename is the output filename, it should be in the build tree.
          major.minor.patch is the version number of the project to be installed
 
      The COMPATIBILITY mode AnyNewerVersion means that the installed
      package version will be considered compatible if it is newer or
      exactly the same as the requested version.  This mode should be used
      for packages which are fully backward compatible, also across major
      versions.  If SameMajorVersion is used instead, then the behaviour
      differs from AnyNewerVersion in that the major version number must be
      the same as requested, e.g.  version 2.0 will not be considered
      compatible if 1.0 is requested.  This mode should be used for packages
      which guarantee backward compatibility within the same major version.
      If ExactVersion is used, then the package is only considered
      compatible if the requested version matches exactly its own version
      number (not considering the tweak version).  For example, version
      1.2.3 of a package is only considered compatible to requested version
      1.2.3.  This mode is for packages without compatibility guarantees.
      If your project has more elaborated version matching rules, you will
      need to write your own custom ConfigVersion.cmake file instead of
      using this macro.
 
      Internally, this macro executes configure_file() to create the
      resulting version file.  Depending on the COMPATIBLITY, either the
      file BasicConfigVersion-SameMajorVersion.cmake.in or
      BasicConfigVersion-AnyNewerVersion.cmake.in is used.  Please note that
      these two files are internal to CMake and you should not call
      configure_file() on them yourself, but they can be used as starting
      point to create more sophisticted custom ConfigVersion.cmake files.
 
     
 
      Example using both configure_package_config_file() and
      write_basic_package_version_file(): CMakeLists.txt:
 
          set(INCLUDE_INSTALL_DIR include/ ... CACHE )
          set(LIB_INSTALL_DIR lib/ ... CACHE )
          set(SYSCONFIG_INSTALL_DIR etc/foo/ ... CACHE )
          ...
          include(CMakePackageConfigHelpers)
          configure_package_config_file(FooConfig.cmake.in ${CMAKE_CURRENT_BINARY_DIR}/FooConfig.cmake
                                        INSTALL_DESTINATION ${LIB_INSTALL_DIR}/Foo/cmake
                                        PATH_VARS INCLUDE_INSTALL_DIR SYSCONFIG_INSTALL_DIR)
          write_basic_package_version_file(${CMAKE_CURRENT_BINARY_DIR}/FooConfigVersion.cmake
                                          VERSION 1.2.3
                                          COMPATIBILITY SameMajorVersion )
          install(FILES ${CMAKE_CURRENT_BINARY_DIR}/FooConfig.cmake ${CMAKE_CURRENT_BINARY_DIR}/FooConfigVersion.cmake
                  DESTINATION ${LIB_INSTALL_DIR}/Foo/cmake )
 
     
 
      With a FooConfig.cmake.in:
 
          set(FOO_VERSION x.y.z)
          ...
          @PACKAGE_INIT@
          ...
          set_and_check(FOO_INCLUDE_DIR "@PACKAGE_INCLUDE_INSTALL_DIR@")
          set_and_check(FOO_SYSCONFIG_DIR "@PACKAGE_SYSCONFIG_INSTALL_DIR@")
 
     
 
          check_required_components(Foo)
 
 
  CMakeParseArguments
       
 
      CMAKE_PARSE_ARGUMENTS(<prefix> <options> <one_value_keywords>
      <multi_value_keywords> args...)
 
      CMAKE_PARSE_ARGUMENTS() is intended to be used in macros or functions
      for parsing the arguments given to that macro or function.  It
      processes the arguments and defines a set of variables which hold the
      values of the respective options.
 
      The <options> argument contains all options for the respective macro,
      i.e.  keywords which can be used when calling the macro without any
      value following, like e.g.  the OPTIONAL keyword of the install()
      command.
 
      The <one_value_keywords> argument contains all keywords for this macro
      which are followed by one value, like e.g.  DESTINATION keyword of the
      install() command.
 
      The <multi_value_keywords> argument contains all keywords for this
      macro which can be followed by more than one value, like e.g.  the
      TARGETS or FILES keywords of the install() command.
 
      When done, CMAKE_PARSE_ARGUMENTS() will have defined for each of the
      keywords listed in <options>, <one_value_keywords> and
      <multi_value_keywords> a variable composed of the given <prefix>
      followed by "_" and the name of the respective keyword.  These
      variables will then hold the respective value from the argument list.
      For the <options> keywords this will be TRUE or FALSE.
 
      All remaining arguments are collected in a variable
      <prefix>_UNPARSED_ARGUMENTS, this can be checked afterwards to see
      whether your macro was called with unrecognized parameters.
 
      As an example here a my_install() macro, which takes similar arguments
      as the real install() command:
 
          function(MY_INSTALL)
            set(options OPTIONAL FAST)
            set(oneValueArgs DESTINATION RENAME)
            set(multiValueArgs TARGETS CONFIGURATIONS)
            cmake_parse_arguments(MY_INSTALL "${options}" "${oneValueArgs}" "${multiValueArgs}" ${ARGN} )
            ...
 
     
 
      Assume my_install() has been called like this:
 
          my_install(TARGETS foo bar DESTINATION bin OPTIONAL blub)
 
     
 
      After the cmake_parse_arguments() call the macro will have set the
      following variables:
 
          MY_INSTALL_OPTIONAL = TRUE
          MY_INSTALL_FAST = FALSE (this option was not used when calling my_install()
          MY_INSTALL_DESTINATION = "bin"
          MY_INSTALL_RENAME = "" (was not used)
          MY_INSTALL_TARGETS = "foo;bar"
          MY_INSTALL_CONFIGURATIONS = "" (was not used)
          MY_INSTALL_UNPARSED_ARGUMENTS = "blub" (no value expected after "OPTIONAL"
 
     
 
      You can the continue and process these variables.
 
      Keywords terminate lists of values, e.g.  if directly after a
      one_value_keyword another recognized keyword follows, this is
      interpreted as the beginning of the new option.  E.g.
      my_install(TARGETS foo DESTINATION OPTIONAL) would result in
      MY_INSTALL_DESTINATION set to "OPTIONAL", but MY_INSTALL_DESTINATION
      would be empty and MY_INSTALL_OPTIONAL would be set to TRUE therefor.
 
  CMakePrintSystemInformation
      print system information
 
      This file can be used for diagnostic purposes just include it in a
      project to see various internal CMake variables.
 
  CMakePushCheckState
       
 
      This module defines two macros: CMAKE_PUSH_CHECK_STATE() and
      CMAKE_POP_CHECK_STATE() These two macros can be used to save and
      restore the state of the variables CMAKE_REQUIRED_FLAGS,
      CMAKE_REQUIRED_DEFINITIONS, CMAKE_REQUIRED_LIBRARIES and
      CMAKE_REQUIRED_INCLUDES used by the various Check-files coming with
      CMake, like e.g.  check_function_exists() etc.  The variable contents
      are pushed on a stack, pushing multiple times is supported.  This is
      useful e.g.  when executing such tests in a Find-module, where they
      have to be set, but after the Find-module has been executed they
      should have the same value as they had before.
 
      Usage:
 
          cmake_push_check_state()
          set(CMAKE_REQUIRED_DEFINITIONS ${CMAKE_REQUIRED_DEFINITIONS} -DSOME_MORE_DEF)
          check_function_exists(...)
          cmake_pop_check_state()
 
 
  CMakeVerifyManifest
       
 
      CMakeVerifyManifest.cmake
 
      This script is used to verify that embeded manifests and side by side
      manifests for a project match.  To run this script, cd to a directory
      and run the script with cmake -P.  On the command line you can pass in
      versions that are OK even if not found in the .manifest files.  For
      example, cmake -Dallow_versions=8.0.50608.0
      -PCmakeVerifyManifest.cmake could be used to allow an embeded manifest
      of 8.0.50608.0 to be used in a project even if that version was not
      found in the .manifest file.
 
  CPack
      Build binary and source package installers.
 
      The CPack module generates binary and source installers in a variety
      of formats using the cpack program.  Inclusion of the CPack module
      adds two new targets to the resulting makefiles, package and
      package_source, which build the binary and source installers,
      respectively.  The generated binary installers contain everything
      installed via CMake's INSTALL command (and the deprecated
      INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).
 
      For certain kinds of binary installers (including the graphical
      installers on Mac OS X and Windows), CPack generates installers that
      allow users to select individual application components to install.
      See CPackComponent module for that.
 
      The CPACK_GENERATOR variable has different meanings in different
      contexts.  In your CMakeLists.txt file, CPACK_GENERATOR is a *list of
      generators*: when run with no other arguments, CPack will iterate over
      that list and produce one package for each generator.  In a
      CPACK_PROJECT_CONFIG_FILE, though, CPACK_GENERATOR is a *string naming
      a single generator*.  If you need per-cpack- generator logic to
      control *other* cpack settings, then you need a
      CPACK_PROJECT_CONFIG_FILE.
 
      The CMake source tree itself contains a CPACK_PROJECT_CONFIG_FILE.
      See the top level file CMakeCPackOptions.cmake.in for an example.
 
      If set, the CPACK_PROJECT_CONFIG_FILE is included automatically on a
      per-generator basis.  It only need contain overrides.
 
      Here's how it works:
 
        - cpack runs
        - it includes CPackConfig.cmake
        - it iterates over the generators listed in that file's
          CPACK_GENERATOR list variable (unless told to use just a
          specific one via -G on the command line...)
 
     
 
        - foreach generator, it then
          - sets CPACK_GENERATOR to the one currently being iterated
          - includes the CPACK_PROJECT_CONFIG_FILE
          - produces the package for that generator
 
     
 
      This is the key: For each generator listed in CPACK_GENERATOR in
      CPackConfig.cmake, cpack will *reset* CPACK_GENERATOR internally to
      *the one currently being used* and then include the
      CPACK_PROJECT_CONFIG_FILE.
 
      Before including this CPack module in your CMakeLists.txt file, there
      are a variety of variables that can be set to customize the resulting
      installers.  The most commonly-used variables are:
 
        CPACK_PACKAGE_NAME - The name of the package (or application). If
        not specified, defaults to the project name.
 
     
 
        CPACK_PACKAGE_VENDOR - The name of the package vendor. (e.g.,
        "Kitware").
 
     
 
        CPACK_PACKAGE_DIRECTORY - The directory in which CPack is doing its
        packaging. If it is not set then this will default (internally) to the
        build dir. This variable may be defined in CPack config file or from
        the cpack command line option "-B". If set the command line option
        override the value found in the config file.
 
     
 
        CPACK_PACKAGE_VERSION_MAJOR - Package major Version
 
     
 
        CPACK_PACKAGE_VERSION_MINOR - Package minor Version
 
     
 
        CPACK_PACKAGE_VERSION_PATCH - Package patch Version
 
     
 
        CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the
        project. Used, for example, the introduction screen of a
        CPack-generated Windows installer to describe the project.
 
     
 
        CPACK_PACKAGE_DESCRIPTION_SUMMARY - Short description of the
        project (only a few words).
 
     
 
        CPACK_PACKAGE_FILE_NAME - The name of the package file to generate,
        not including the extension. For example, cmake-2.6.1-Linux-i686.
        The default value is
 
     
 
        ${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}.
 
     
 
        CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the
        target system. This may be used by some CPack generators
        like NSIS to create an installation directory e.g., "CMake 2.5"
        below the installation prefix. All installed element will be
        put inside this directory.
 
     
 
          CPACK_PACKAGE_ICON - A branding image that will be displayed inside
          the installer (used by GUI installers).
 
     
 
        CPACK_PROJECT_CONFIG_FILE - CPack-time project CPack configuration
        file. This file included at cpack time, once per
        generator after CPack has set CPACK_GENERATOR to the actual generator
        being used. It allows per-generator setting of CPACK_* variables at
        cpack time.
 
     
 
        CPACK_RESOURCE_FILE_LICENSE - License to be embedded in the installer. It
        will typically be displayed to the user by the produced installer
        (often with an explicit "Accept" button, for graphical installers)
        prior to installation. This license file is NOT added to installed
        file but is used by some CPack generators like NSIS. If you want
        to install a license file (may be the same as this one)
        along with your project you must add an appropriate CMake INSTALL
        command in your CMakeLists.txt.
 
     
 
        CPACK_RESOURCE_FILE_README - ReadMe file to be embedded in the installer. It
        typically describes in some detail the purpose of the project
        during the installation. Not all CPack generators uses
        this file.
 
     
 
        CPACK_RESOURCE_FILE_WELCOME - Welcome file to be embedded in the
        installer. It welcomes users to this installer.
        Typically used in the graphical installers on Windows and Mac OS X.
 
     
 
        CPACK_MONOLITHIC_INSTALL - Disables the component-based
        installation mechanism. When set the component specification is ignored
        and all installed items are put in a single "MONOLITHIC" package.
        Some CPack generators do monolithic packaging by default and
        may be asked to do component packaging by setting
        CPACK_<GENNAME>_COMPONENT_INSTALL to 1/TRUE.
 
     
 
        CPACK_GENERATOR - List of CPack generators to use. If not
        specified, CPack will create a set of options CPACK_BINARY_<GENNAME> (e.g.,
        CPACK_BINARY_NSIS) allowing the user to enable/disable individual
        generators. This variable may be used on the command line
        as well as in:
 
     
 
          cpack -D CPACK_GENERATOR="ZIP;TGZ" /path/to/build/tree
 
     
 
        CPACK_OUTPUT_CONFIG_FILE - The name of the CPack binary configuration
        file. This file is the CPack configuration generated by the CPack module
        for binary installers. Defaults to CPackConfig.cmake.
 
     
 
        CPACK_PACKAGE_EXECUTABLES - Lists each of the executables and associated
        text label to be used to create Start Menu shortcuts. For example,
        setting this to the list ccmake;CMake will
        create a shortcut named "CMake" that will execute the installed
        executable ccmake. Not all CPack generators use it (at least NSIS and
        OSXX11 do).
 
     
 
        CPACK_STRIP_FILES - List of files to be stripped. Starting with
        CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which
        enables stripping of all files (a list of files evaluates to TRUE
        in CMake, so this change is compatible).
 
     
 
      The following CPack variables are specific to source packages, and
      will not affect binary packages:
 
        CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package. For
        example cmake-2.6.1.
 
     
 
        CPACK_SOURCE_STRIP_FILES - List of files in the source tree that
        will be stripped. Starting with CMake 2.6.0
        CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables
        stripping of all files (a list of files evaluates to TRUE in CMake,
        so this change is compatible).
 
     
 
        CPACK_SOURCE_GENERATOR - List of generators used for the source
        packages. As with CPACK_GENERATOR, if this is not specified then
        CPack will create a set of options (e.g., CPACK_SOURCE_ZIP)
        allowing users to select which packages will be generated.
 
     
 
        CPACK_SOURCE_OUTPUT_CONFIG_FILE - The name of the CPack source
        configuration file. This file is the CPack configuration generated by the
        CPack module for source installers. Defaults to CPackSourceConfig.cmake.
 
     
 
        CPACK_SOURCE_IGNORE_FILES - Pattern of files in the source tree
        that won't be packaged when building a source package. This is a
        list of regular expression patterns (that must be properly escaped),
        e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*
 
     
 
      The following variables are for advanced uses of CPack:
 
        CPACK_CMAKE_GENERATOR - What CMake generator should be used if the
        project is CMake project. Defaults to the value of CMAKE_GENERATOR
        few users will want to change this setting.
 
     
 
        CPACK_INSTALL_CMAKE_PROJECTS - List of four values that specify
        what project to install. The four values are: Build directory,
        Project Name, Project Component, Directory. If omitted, CPack will
        build an installer that installers everything.
 
     
 
        CPACK_SYSTEM_NAME - System name, defaults to the value of
        ${CMAKE_SYSTEM_NAME}.
 
     
 
        CPACK_PACKAGE_VERSION - Package full version, used internally. By
        default, this is built from CPACK_PACKAGE_VERSION_MAJOR,
        CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH.
 
     
 
        CPACK_TOPLEVEL_TAG - Directory for the installed files.
 
     
 
        CPACK_INSTALL_COMMANDS - Extra commands to install components.
 
     
 
        CPACK_INSTALLED_DIRECTORIES - Extra directories to install.
 
     
 
          CPACK_PACKAGE_INSTALL_REGISTRY_KEY - Registry key used when
          installing this project. This is only used
          by installer for Windows.
          CPACK_CREATE_DESKTOP_LINKS - List of desktop links to create.
 
     
 
 
  CPackBundle
      CPack Bundle generator (Mac OS X) specific options
 
     
 
      Installers built on Mac OS X using the Bundle generator use the
      aforementioned DragNDrop (CPACK_DMG_xxx) variables, plus the following
      Bundle-specific parameters (CPACK_BUNDLE_xxx).
 
        CPACK_BUNDLE_NAME - The name of the generated bundle. This
        appears in the OSX finder as the bundle name. Required.
 
     
 
        CPACK_BUNDLE_PLIST - Path to an OSX plist file that will be used
        for the generated bundle. This assumes that the caller has generated
        or specified their own Info.plist file. Required.
 
     
 
        CPACK_BUNDLE_ICON - Path to an OSX icon file that will be used as
        the icon for the generated bundle. This is the icon that appears in the
        OSX finder for the bundle, and in the OSX dock when the bundle is opened.
        Required.
 
     
 
        CPACK_BUNDLE_STARTUP_COMMAND - Path to a startup script. This is a path to
        an executable or script that will be run whenever an end-user double-clicks
        the generated bundle in the OSX Finder. Optional.
 
 
  CPackComponent
      Build binary and source package installers
 
     
 
      The CPackComponent module is the module which handles the component
      part of CPack.  See CPack module for general information about CPack.
 
      For certain kinds of binary installers (including the graphical
      installers on Mac OS X and Windows), CPack generates installers that
      allow users to select individual application components to install.
      The contents of each of the components are identified by the COMPONENT
      argument of CMake's INSTALL command.  These components can be
      annotated with user-friendly names and descriptions, inter-component
      dependencies, etc., and grouped in various ways to customize the
      resulting installer.  See the cpack_add_* commands, described below,
      for more information about component-specific installations.
 
      Component-specific installation allows users to select specific sets
      of components to install during the install process.  Installation
      components are identified by the COMPONENT argument of CMake's INSTALL
      commands, and should be further described by the following CPack
      commands:
 
        CPACK_COMPONENTS_ALL - The list of component to install.
 
     
 
      The default value of this variable is computed by CPack and contains
      all components defined by the project.  The user may set it to only
      include the specified components.
 
        CPACK_<GENNAME>_COMPONENT_INSTALL - Enable/Disable component install for
        CPack generator <GENNAME>.
 
     
 
      Each CPack Generator (RPM, DEB, ARCHIVE, NSIS, DMG, etc...) has a
      legacy default behavior.  e.g.  RPM builds monolithic whereas NSIS
      builds component.  One can change the default behavior by setting this
      variable to 0/1 or OFF/ON.
 
        CPACK_COMPONENTS_GROUPING - Specify how components are grouped for multi-package
        component-aware CPack generators.
 
     
 
      Some generators like RPM or ARCHIVE family (TGZ, ZIP, ...) generates
      several packages files when asked for component packaging.  They group
      the component differently depending on the value of this variable:
 
        - ONE_PER_GROUP (default): creates one package file per component group
        - ALL_COMPONENTS_IN_ONE : creates a single package with all (requested) component
        - IGNORE : creates one package per component, i.e. IGNORE component group
 
      One can specify different grouping for different CPack generator by
      using a CPACK_PROJECT_CONFIG_FILE.
 
        CPACK_COMPONENT_<compName>_DISPLAY_NAME - The name to be displayed for a component.
        CPACK_COMPONENT_<compName>_DESCRIPTION - The description of a component.
        CPACK_COMPONENT_<compName>_GROUP - The group of a component.
        CPACK_COMPONENT_<compName>_DEPENDS - The dependencies (list of components)
        on which this component depends.
        CPACK_COMPONENT_<compName>_REQUIRED - True is this component is required.
 
      cpack_add_component - Describes a CPack installation component named
      by the COMPONENT argument to a CMake INSTALL command.
 
        cpack_add_component(compname
                            [DISPLAY_NAME name]
                            [DESCRIPTION description]
                            [HIDDEN | REQUIRED | DISABLED ]
                            [GROUP group]
                            [DEPENDS comp1 comp2 ... ]
                            [INSTALL_TYPES type1 type2 ... ]
                            [DOWNLOADED]
                            [ARCHIVE_FILE filename])
 
     
 
      The cmake_add_component command describes an installation component,
      which the user can opt to install or remove as part of the graphical
      installation process.  compname is the name of the component, as
      provided to the COMPONENT argument of one or more CMake INSTALL
      commands.
 
      DISPLAY_NAME is the displayed name of the component, used in graphical
      installers to display the component name.  This value can be any
      string.
 
      DESCRIPTION is an extended description of the component, used in
      graphical installers to give the user additional information about the
      component.  Descriptions can span multiple lines using "\n" as the
      line separator.  Typically, these descriptions should be no more than
      a few lines long.
 
      HIDDEN indicates that this component will be hidden in the graphical
      installer, so that the user cannot directly change whether it is
      installed or not.
 
      REQUIRED indicates that this component is required, and therefore will
      always be installed.  It will be visible in the graphical installer,
      but it cannot be unselected.  (Typically, required components are
      shown greyed out).
 
      DISABLED indicates that this component should be disabled (unselected)
      by default.  The user is free to select this component for
      installation, unless it is also HIDDEN.
 
      DEPENDS lists the components on which this component depends.  If this
      component is selected, then each of the components listed must also be
      selected.  The dependency information is encoded within the installer
      itself, so that users cannot install inconsistent sets of components.
 
      GROUP names the component group of which this component is a part.  If
      not provided, the component will be a standalone component, not part
      of any component group.  Component groups are described with the
      cpack_add_component_group command, detailed below.
 
      INSTALL_TYPES lists the installation types of which this component is
      a part.  When one of these installations types is selected, this
      component will automatically be selected.  Installation types are
      described with the cpack_add_install_type command, detailed below.
 
      DOWNLOADED indicates that this component should be downloaded
      on-the-fly by the installer, rather than packaged in with the
      installer itself.  For more information, see the
      cpack_configure_downloads command.
 
      ARCHIVE_FILE provides a name for the archive file created by CPack to
      be used for downloaded components.  If not supplied, CPack will create
      a file with some name based on CPACK_PACKAGE_FILE_NAME and the name of
      the component.  See cpack_configure_downloads for more information.
 
      cpack_add_component_group - Describes a group of related CPack
      installation components.
 
        cpack_add_component_group(groupname
                                  [DISPLAY_NAME name]
                                  [DESCRIPTION description]
                                  [PARENT_GROUP parent]
                                  [EXPANDED]
                                  [BOLD_TITLE])
 
     
 
      The cpack_add_component_group describes a group of installation
      components, which will be placed together within the listing of
      options.  Typically, component groups allow the user to
      select/deselect all of the components within a single group via a
      single group-level option.  Use component groups to reduce the
      complexity of installers with many options.  groupname is an arbitrary
      name used to identify the group in the GROUP argument of the
      cpack_add_component command, which is used to place a component in a
      group.  The name of the group must not conflict with the name of any
      component.
 
      DISPLAY_NAME is the displayed name of the component group, used in
      graphical installers to display the component group name.  This value
      can be any string.
 
      DESCRIPTION is an extended description of the component group, used in
      graphical installers to give the user additional information about the
      components within that group.  Descriptions can span multiple lines
      using "\n" as the line separator.  Typically, these descriptions
      should be no more than a few lines long.
 
      PARENT_GROUP, if supplied, names the parent group of this group.
      Parent groups are used to establish a hierarchy of groups, providing
      an arbitrary hierarchy of groups.
 
      EXPANDED indicates that, by default, the group should show up as
      "expanded", so that the user immediately sees all of the components
      within the group.  Otherwise, the group will initially show up as a
      single entry.
 
      BOLD_TITLE indicates that the group title should appear in bold, to
      call the user's attention to the group.
 
      cpack_add_install_type - Add a new installation type containing a set
      of predefined component selections to the graphical installer.
 
        cpack_add_install_type(typename
                                [DISPLAY_NAME name])
 
     
 
      The cpack_add_install_type command identifies a set of preselected
      components that represents a common use case for an application.  For
      example, a "Developer" install type might include an application along
      with its header and library files, while an "End user" install type
      might just include the application's executable.  Each component
      identifies itself with one or more install types via the INSTALL_TYPES
      argument to cpack_add_component.
 
      DISPLAY_NAME is the displayed name of the install type, which will
      typically show up in a drop-down box within a graphical installer.
      This value can be any string.
 
      cpack_configure_downloads - Configure CPack to download selected
      components on-the-fly as part of the installation process.
 
        cpack_configure_downloads(site
                                  [UPLOAD_DIRECTORY dirname]
                                  [ALL]
                                  [ADD_REMOVE|NO_ADD_REMOVE])
 
     
 
      The cpack_configure_downloads command configures installation-time
      downloads of selected components.  For each downloadable component,
      CPack will create an archive containing the contents of that
      component, which should be uploaded to the given site.  When the user
      selects that component for installation, the installer will download
      and extract the component in place.  This feature is useful for
      creating small installers that only download the requested components,
      saving bandwidth.  Additionally, the installers are small enough that
      they will be installed as part of the normal installation process, and
      the "Change" button in Windows Add/Remove Programs control panel will
      allow one to add or remove parts of the application after the original
      installation.  On Windows, the downloaded-components functionality
      requires the ZipDLL plug-in for NSIS, available at:
 
        http://nsis.sourceforge.net/ZipDLL_plug-in
 
     
 
      On Mac OS X, installers that download components on-the-fly can only
      be built and installed on system using Mac OS X 10.5 or later.
 
      The site argument is a URL where the archives for downloadable
      components will reside, e.g.,
      http://www.cmake.org/files/2.6.1/installer/ All of the archives
      produced by CPack should be uploaded to that location.
 
      UPLOAD_DIRECTORY is the local directory where CPack will create the
      various archives for each of the components.  The contents of this
      directory should be uploaded to a location accessible by the URL given
      in the site argument.  If omitted, CPack will use the directory
      CPackUploads inside the CMake binary directory to store the generated
      archives.
 
      The ALL flag indicates that all components be downloaded.  Otherwise,
      only those components explicitly marked as DOWNLOADED or that have a
      specified ARCHIVE_FILE will be downloaded.  Additionally, the ALL
      option implies ADD_REMOVE (unless NO_ADD_REMOVE is specified).
 
      ADD_REMOVE indicates that CPack should install a copy of the installer
      that can be called from Windows' Add/Remove Programs dialog (via the
      "Modify" button) to change the set of installed components.
      NO_ADD_REMOVE turns off this behavior.  This option is ignored on Mac
      OS X.
 
  CPackCygwin
      Cygwin CPack generator (Cygwin).
 
      The following variable is specific to installers build on and/or for
      Cygwin:
 
          CPACK_CYGWIN_PATCH_NUMBER - The Cygwin patch number.
          FIXME: This documentation is incomplete.
          CPACK_CYGWIN_PATCH_FILE - The Cygwin patch file.
          FIXME: This documentation is incomplete.
          CPACK_CYGWIN_BUILD_SCRIPT - The Cygwin build script.
          FIXME: This documentation is incomplete.
 
 
  CPackDMG
      DragNDrop CPack generator (Mac OS X).
 
      The following variables are specific to the DragNDrop installers built
      on Mac OS X:
 
        CPACK_DMG_VOLUME_NAME - The volume name of the generated disk
        image. Defaults to CPACK_PACKAGE_FILE_NAME.
 
     
 
        CPACK_DMG_FORMAT - The disk image format. Common values are UDRO
        (UDIF read-only), UDZO (UDIF zlib-compressed) or UDBZ (UDIF
        bzip2-compressed). Refer to hdiutil(1) for more information on
        other available formats.
 
     
 
        CPACK_DMG_DS_STORE - Path to a custom DS_Store file. This .DS_Store
        file e.g. can be used to specify the Finder window
        position/geometry and layout (such as hidden toolbars, placement of the
        icons etc.). This file has to be generated by the Finder (either manually or
        through OSA-script) using a normal folder from which the .DS_Store
        file can then be extracted.
 
     
 
        CPACK_DMG_BACKGROUND_IMAGE - Path to a background image file. This
        file will be used as the background for the Finder Window when the disk
        image is opened.  By default no background image is set. The background
        image is applied after applying the custom .DS_Store file.
 
     
 
        CPACK_COMMAND_HDIUTIL - Path to the hdiutil(1) command used to
        operate on disk image files on Mac OS X. This variable can be used
        to override the automatically detected command (or specify its
        location if the auto-detection fails to find it.)
 
     
 
        CPACK_COMMAND_SETFILE - Path to the SetFile(1) command used to set
        extended attributes on files and directories on Mac OS X. This
        variable can be used to override the automatically detected
        command (or specify its location if the auto-detection fails to
        find it.)
 
     
 
        CPACK_COMMAND_REZ - Path to the Rez(1) command used to compile
        resources on Mac OS X. This variable can be used to override the
        automatically detected command (or specify its location if the
        auto-detection fails to find it.)
 
 
  CPackDeb
      The builtin (binary) CPack Deb generator (Unix only)
 
      CPackDeb may be used to create Deb package using CPack.  CPackDeb is a
      CPack generator thus it uses the CPACK_XXX variables used by CPack :
      http://www.cmake.org/Wiki/CMake:CPackConfiguration.  CPackDeb
      generator should work on any linux host but it will produce better deb
      package when Debian specific tools 'dpkg-xxx' are usable on the build
      system.
 
      CPackDeb has specific features which are controlled by the specifics
      CPACK_DEBIAN_XXX variables.You'll find a detailed usage on the wiki:
 
        http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#DEB_.28UNIX_only.29
 
      However as a handy reminder here comes the list of specific variables:

            Mandatory : NO
            Default  : OFF
            May be set to ON in order to use dpkg-shlibdeps to generate
            better package dependency list.
            You may need set CMAKE_INSTALL_RPATH toi appropriate value
            if you use this feature, because if you don't dpkg-shlibdeps
            may fail to find your own shared libs.
            See http://www.cmake.org/Wiki/CMake_RPATH_handling.
 
      CPACK_DEBIAN_PACKAGE_DEBUG

          If this is set to "ON", then an installer will look for previous
          installed versions and if one is found, ask the user whether to
          uninstall it before proceeding with the install.
 
     
 
          CPACK_NSIS_MODIFY_PATH - Modify PATH toggle.
          If this is set to "ON", then an extra page
          will appear in the installer that will allow the user to choose
          whether the program directory should be added to the system PATH
          variable.
 
     
 
          CPACK_NSIS_DISPLAY_NAME - The display name string that appears in
          the Windows Add/Remove Program control panel

          uninstall start menu shortcuts.
 
     
 
          CPACK_NSIS_EXECUTABLES_DIRECTORY - Creating NSIS start menu links
          assumes that they are in 'bin' unless this variable is set.
          For example, you would set this to 'exec' if your executables are
          in an exec directory.
 
     
 
          CPACK_NSIS_MUI_FINISHPAGE_RUN - Specify an executable to add an option
          to run on the finish page of the NSIS installer.
          CPACK_NSIS_MENU_LINKS - Specify links in [application] menu.

                "http://www.cmake.org" "CMake Web Site")
 
 
  CPackPackageMaker
      PackageMaker CPack generator (Mac OS X).
 
      The following variable is specific to installers build on Mac OS X
      using PackageMaker:
 
        CPACK_OSX_PACKAGE_VERSION - The version of Mac OS X that the
        resulting PackageMaker archive should be compatible with. Different
        versions of Mac OS X support different
        features. For example, CPack can only build component-based
        installers for Mac OS X 10.4 or newer, and can only build
        installers that download component son-the-fly for Mac OS X 10.5
        or newer. If left blank, this value will be set to the minimum
        version of Mac OS X that supports the requested features. Set this
        variable to some value (e.g., 10.4) only if you want to guarantee
        that your installer will work on that version of Mac OS X, and
        don't mind missing extra features available in the installer
        shipping with later versions of Mac OS X.
 
 
  CPackRPM
      The builtin (binary) CPack RPM generator (Unix only)
 
      CPackRPM may be used to create RPM package using CPack.  CPackRPM is a
      CPack generator thus it uses the CPACK_XXX variables used by CPack :
      http://www.cmake.org/Wiki/CMake:CPackConfiguration
 
      However CPackRPM has specific features which are controlled by the
      specifics CPACK_RPM_XXX variables.  CPackRPM is a component aware
      generator so when CPACK_RPM_COMPONENT_INSTALL is ON some more
      CPACK_RPM_<ComponentName>_XXXX variables may be used in order to have
      component specific values.  Note however that <componentName> refers
      to the **grouping name**.  This may be either a component name or a
      component GROUP name.  Usually those vars correspond to RPM spec file
      entities, one may find information about spec files here
      http://www.rpm.org/wiki/Docs.  You'll find a detailed usage of
      CPackRPM on the wiki:
 
        http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#RPM_.28Unix_Only.29
 
      However as a handy reminder here comes the list of specific variables:
 
        CPACK_RPM_PACKAGE_SUMMARY - The RPM package summary.
            Mandatory : YES
            Default  : CPACK_PACKAGE_DESCRIPTION_SUMMARY
        CPACK_RPM_PACKAGE_NAME - The RPM package name.
            Mandatory : YES
            Default  : CPACK_PACKAGE_NAME
        CPACK_RPM_PACKAGE_VERSION - The RPM package version.
            Mandatory : YES
            Default  : CPACK_PACKAGE_VERSION
        CPACK_RPM_PACKAGE_ARCHITECTURE - The RPM package architecture.

            Default  : -
            This may be set to "noarch" if you
            know you are building a noarch package.
        CPACK_RPM_PACKAGE_RELEASE - The RPM package release.
            Mandatory : YES
            Default  : 1
            This is the numbering of the RPM package
            itself, i.e. the version of the packaging and not the version of the
            content (see CPACK_RPM_PACKAGE_VERSION). One may change the default
            value if the previous packaging was buggy and/or you want to put here
            a fancy Linux distro specific numbering.
        CPACK_RPM_PACKAGE_LICENSE - The RPM package license policy.
            Mandatory : YES
            Default  : "unknown"
        CPACK_RPM_PACKAGE_GROUP - The RPM package group.
            Mandatory : YES
            Default  : "unknown"
        CPACK_RPM_PACKAGE_VENDOR - The RPM package vendor.
            Mandatory : YES
            Default  : CPACK_PACKAGE_VENDOR if set or "unknown"
        CPACK_RPM_PACKAGE_URL - The projects URL.
            Mandatory : NO
            Default  : -
        CPACK_RPM_PACKAGE_DESCRIPTION - RPM package description.
            Mandatory : YES
            Default  : CPACK_PACKAGE_DESCRIPTION_FILE if set or "no package description available"
        CPACK_RPM_COMPRESSION_TYPE - RPM compression type.
            Mandatory : NO
            Default  : -
            May be used to override RPM compression type to be used
            to build the RPM. For example some Linux distribution now default
            to lzma or xz compression whereas older cannot use such RPM.
            Using this one can enforce compression type to be used.
            Possible value are: lzma, xz, bzip2 and gzip.
        CPACK_RPM_PACKAGE_REQUIRES - RPM spec requires field.
            Mandatory : NO
            Default  : -
            May be used to set RPM dependencies (requires).
            Note that you must enclose the complete requires string between quotes,
            for example:
            set(CPACK_RPM_PACKAGE_REQUIRES "python >= 2.5.0, cmake >= 2.8")
            The required package list of an RPM file could be printed with
            rpm -qp --requires file.rpm
        CPACK_RPM_PACKAGE_SUGGESTS - RPM spec suggest field.
            Mandatory : NO
            Default  : -
            May be used to set weak RPM dependencies (suggests).
            Note that you must enclose the complete requires string between quotes.
        CPACK_RPM_PACKAGE_PROVIDES - RPM spec provides field.
            Mandatory : NO
            Default  : -
            May be used to set RPM dependencies (provides).
            The provided package list of an RPM file could be printed with
            rpm -qp --provides file.rpm
        CPACK_RPM_PACKAGE_OBSOLETES - RPM spec obsoletes field.
            Mandatory : NO
            Default  : -
            May be used to set RPM packages that are obsoleted by this one.
        CPACK_RPM_PACKAGE_RELOCATABLE - build a relocatable RPM.
            Mandatory : NO
            Default  : CPACK_PACKAGE_RELOCATABLE
            If this variable is set to TRUE or ON CPackRPM will try
            to build a relocatable RPM package. A relocatable RPM may
            be installed using rpm --prefix or --relocate in order to
            install it at an alternate place see rpm(8).
            Note that currently this may fail if CPACK_SET_DESTDIR is set to ON.
            If CPACK_SET_DESTDIR is set then you will get a warning message
            but if there is file installed with absolute path you'll get
            unexpected behavior.
        CPACK_RPM_SPEC_INSTALL_POST - [deprecated].
            Mandatory : NO
            Default  : -
            This way of specifying post-install script is deprecated use
            CPACK_RPM_POST_INSTALL_SCRIPT_FILE
            May be used to set an RPM post-install command inside the spec file.
            For example setting it to "/bin/true" may be used to prevent
            rpmbuild to strip binaries.
        CPACK_RPM_SPEC_MORE_DEFINE - RPM extended spec definitions lines.
            Mandatory : NO
            Default  : -
            May be used to add any %define lines to the generated spec file.
        CPACK_RPM_PACKAGE_DEBUG - Toggle CPackRPM debug output.
            Mandatory : NO
            Default  : -
            May be set when invoking cpack in order to trace debug information
            during CPack RPM run. For example you may launch CPack like this
            cpack -D CPACK_RPM_PACKAGE_DEBUG=1 -G RPM
        CPACK_RPM_USER_BINARY_SPECFILE - A user provided spec file.
            Mandatory : NO
            Default  : -
            May be set by the user in order to specify a USER binary spec file
            to be used by CPackRPM instead of generating the file.
            The specified file will be processed by configure_file( @ONLY).
        CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE - Spec file template.
            Mandatory : NO
            Default  : -
            If set CPack will generate a template for USER specified binary
            spec file and stop with an error. For example launch CPack like this
            cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM
            The user may then use this file in order to hand-craft is own
            binary spec file which may be used with CPACK_RPM_USER_BINARY_SPECFILE.
        CPACK_RPM_PRE_INSTALL_SCRIPT_FILE
        CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE
            Mandatory : NO
            Default  : -
            May be used to embed a pre (un)installation script in the spec file.
            The refered script file(s) will be read and directly
            put after the %pre or %preun section
            If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for
            each component can be overridden with
            CPACK_RPM_<COMPONENT>_PRE_INSTALL_SCRIPT_FILE and
            CPACK_RPM_<COMPONENT>_PRE_UNINSTALL_SCRIPT_FILE
            One may verify which scriptlet has been included with
            rpm -qp --scripts  package.rpm
        CPACK_RPM_POST_INSTALL_SCRIPT_FILE
        CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE
            Mandatory : NO
            Default  : -
            May be used to embed a post (un)installation script in the spec file.
            The refered script file(s) will be read and directly
            put after the %post or %postun section
            If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for
            each component can be overridden with
            CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE and
            CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE
            One may verify which scriptlet has been included with
            rpm -qp --scripts  package.rpm
        CPACK_RPM_USER_FILELIST
        CPACK_RPM_<COMPONENT>_USER_FILELIST
            Mandatory : NO
            Default  : -
            May be used to explicitly specify %(<directive>) file line
            in the spec file. Like %config(noreplace) or any other directive
            that be found in the %files section. Since CPackRPM is generating
            the list of files (and directories) the user specified files of
            the CPACK_RPM_<COMPONENT>_USER_FILELIST list will be removed from the generated list.
        CPACK_RPM_CHANGELOG_FILE - RPM changelog file.
            Mandatory : NO
            Default  : -
            May be used to embed a changelog in the spec file.
            The refered file will be read and directly put after the %changelog
            section.
 
 
  CTest
      Configure a project for testing with CTest/CDash
 
      Include this module in the top CMakeLists.txt file of a project to
      enable testing with CTest and dashboard submissions to CDash:
 
          project(MyProject)
          ...
          include(CTest)
 
      The module automatically creates a BUILD_TESTING option that selects
      whether to enable testing support (ON by default).  After including
      the module, use code like
 
          if(BUILD_TESTING)
            # ... CMake code to create tests ...
          endif()
 
      to creating tests when testing is enabled.
 
      To enable submissions to a CDash server, create a CTestConfig.cmake
      file at the top of the project with content such as
 
          set(CTEST_PROJECT_NAME "MyProject")
          set(CTEST_NIGHTLY_START_TIME "01:00:00 UTC")
          set(CTEST_DROP_METHOD "http")
          set(CTEST_DROP_SITE "my.cdash.org")
          set(CTEST_DROP_LOCATION "/submit.php?project=MyProject")
          set(CTEST_DROP_SITE_CDASH TRUE)
 
      (the CDash server can provide the file to a project administrator who
      configures 'MyProject').  Settings in the config file are shared by
      both this CTest module and the CTest command-line tool's dashboard
      script mode (ctest -S).
 
      While building a project for submission to CDash, CTest scans the
      build output for errors and warnings and reports them with surrounding
      context from the build log.  This generic approach works for all build
      tools, but does not give details about the command invocation that
      produced a given problem.  One may get more detailed reports by adding
 
          set(CTEST_USE_LAUNCHERS 1)
 
      to the CTestConfig.cmake file.  When this option is enabled, the CTest
      module tells CMake's Makefile generators to invoke every command in
      the generated build system through a CTest launcher program.
      (Currently the CTEST_USE_LAUNCHERS option is ignored on non-Makefile
      generators.) During a manual build each launcher transparently runs
      the command it wraps.  During a CTest-driven build for submission to
      CDash each launcher reports detailed information when its command
      fails or warns.  (Setting CTEST_USE_LAUNCHERS in CTestConfig.cmake is
      convenient, but also adds the launcher overhead even for manual
      builds.  One may instead set it in a CTest dashboard script and add it
      to the CMake cache for the build tree.)
 
  CTestScriptMode
       
 
      This file is read by ctest in script mode (-S)
 
  CTestUseLaunchers
      Set the RULE_LAUNCH_* global properties when CTEST_USE_LAUNCHERS is
      on.
 
      CTestUseLaunchers is automatically included when you include(CTest).
      However, it is split out into its own module file so projects can use
      the CTEST_USE_LAUNCHERS functionality independently.
 
      To use launchers, set CTEST_USE_LAUNCHERS to ON in a ctest -S
      dashboard script, and then also set it in the cache of the configured
      project.  Both cmake and ctest need to know the value of it for the
      launchers to work properly.  CMake needs to know in order to generate
      proper build rules, and ctest, in order to produce the proper error
      and warning analysis.
 
      For convenience, you may set the ENV variable
      CTEST_USE_LAUNCHERS_DEFAULT in your ctest -S script, too.  Then, as
      long as your CMakeLists uses include(CTest) or
      include(CTestUseLaunchers), it will use the value of the ENV variable
      to initialize a CTEST_USE_LAUNCHERS cache variable.  This cache
      variable initialization only occurs if CTEST_USE_LAUNCHERS is not
      already defined.

      <files> and store the result in a <variable>.  Specify the list of
      files in one argument as a semicolon-separated list.
      CHECK_CXX_SYMBOL_EXISTS() can be used to check in C++ files, as
      opposed to CHECK_SYMBOL_EXISTS(), which works only for C.
 
      If the header files define the symbol as a macro it is considered
      available and assumed to work.  If the header files declare the symbol
      as a function or variable then the symbol must also be available for
      linking.  If the symbol is a type or enum value it will not be
      recognized (consider using CheckTypeSize or CheckCSourceCompiles).
 
      The following variables may be set before calling this macro to modify
      the way the check is run:
 
        CMAKE_REQUIRED_FLAGS = string of compile command line flags
        CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
        CMAKE_REQUIRED_INCLUDES = list of include directories

        CMAKE_REQUIRED_LIBRARIES = list of libraries to link
 
 
  CheckFunctionExists
      Check if a C function can be linked
 
      CHECK_FUNCTION_EXISTS(<function> <variable>)
 
      Check that the <function> is provided by libraries on the system and
      store the result in a <variable>.  This does not verify that any
      system header file declares the function, only that it can be found at
      link time (considure using CheckSymbolExists).
 
      The following variables may be set before calling this macro to modify
      the way the check is run:
 
        CMAKE_REQUIRED_FLAGS = string of compile command line flags
        CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)

        INCLUDE  - name of include file
        VARIABLE - variable to return result
 
     
 
      An optional third argument is the CFlags to add to the compile line or

  CheckLanguage
      Check if a language can be enabled
 
      Usage:
 
        check_language(<lang>)
 
      where <lang> is a language that may be passed to enable_language()
      such as "Fortran".  If CMAKE_<lang>_COMPILER is already defined the
      check does nothing.  Otherwise it tries enabling the language in a
      test project.  The result is cached in CMAKE_<lang>_COMPILER as the
      compiler that was found, or NOTFOUND if the language cannot be
      enabled.
 
      Example:
 
        check_language(Fortran)
        if(CMAKE_Fortran_COMPILER)
          enable_language(Fortran)
        else()
          message(STATUS "No Fortran support")
        endif()
 
 
  CheckLibraryExists
      Check if the function exists.
 
      CHECK_LIBRARY_EXISTS (LIBRARY FUNCTION LOCATION VARIABLE)
 
        LIBRARY  - the name of the library you are looking for
        FUNCTION - the name of the function
        LOCATION - location where the library should be found
        VARIABLE - variable to store the result
 
     
 
      The following variables may be set before calling this macro to modify
      the way the check is run:
 
        CMAKE_REQUIRED_FLAGS = string of compile command line flags
        CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
        CMAKE_REQUIRED_LIBRARIES = list of libraries to link
 
 
  CheckPrototypeDefinition
      Check if the protoype we expect is correct.
 
      check_prototype_definition(FUNCTION PROTOTYPE RETURN HEADER VARIABLE)
 
        FUNCTION - The name of the function (used to check if prototype exists)
        PROTOTYPE- The prototype to check.
        RETURN - The return value of the function.
        HEADER - The header files required.
        VARIABLE - The variable to store the result.
 
      Example:
 
        check_prototype_definition(getpwent_r
          "struct passwd *getpwent_r(struct passwd *src, char *buf, int buflen)"
          "NULL"
          "unistd.h;pwd.h"
          SOLARIS_GETPWENT_R)
 
      The following variables may be set before calling this macro to modify
      the way the check is run:
 
        CMAKE_REQUIRED_FLAGS = string of compile command line flags
        CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
        CMAKE_REQUIRED_INCLUDES = list of include directories
        CMAKE_REQUIRED_LIBRARIES = list of libraries to link
 
 
  CheckStructHasMember
      Check if the given struct or class has the specified member variable
 
      CHECK_STRUCT_HAS_MEMBER (STRUCT MEMBER HEADER VARIABLE)
 
        STRUCT - the name of the struct or class you are interested in
        MEMBER - the member which existence you want to check
        HEADER - the header(s) where the prototype should be declared
        VARIABLE - variable to store the result
 
     
 
      The following variables may be set before calling this macro to modify
      the way the check is run:
 
        CMAKE_REQUIRED_FLAGS = string of compile command line flags
        CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
        CMAKE_REQUIRED_INCLUDES = list of include directories
 
     
 
      Example: CHECK_STRUCT_HAS_MEMBER("struct timeval" tv_sec sys/select.h
      HAVE_TIMEVAL_TV_SEC)
 
  CheckSymbolExists
      Check if a symbol exists as a function, variable, or macro
 
      CHECK_SYMBOL_EXISTS(<symbol> <files> <variable>)
 
      Check that the <symbol> is available after including given header
      <files> and store the result in a <variable>.  Specify the list of
      files in one argument as a semicolon-separated list.
 
      If the header files define the symbol as a macro it is considered
      available and assumed to work.  If the header files declare the symbol
      as a function or variable then the symbol must also be available for
      linking.  If the symbol is a type or enum value it will not be
      recognized (consider using CheckTypeSize or CheckCSourceCompiles).  If
      the check needs to be done in C++, consider using
      CHECK_CXX_SYMBOL_EXISTS(), which does the same as
      CHECK_SYMBOL_EXISTS(), but in C++.
 
      The following variables may be set before calling this macro to modify
      the way the check is run:
 
        CMAKE_REQUIRED_FLAGS = string of compile command line flags
        CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
        CMAKE_REQUIRED_INCLUDES = list of include directories
        CMAKE_REQUIRED_LIBRARIES = list of libraries to link
 
 
  CheckTypeSize
      Check sizeof a type
 
        CHECK_TYPE_SIZE(TYPE VARIABLE [BUILTIN_TYPES_ONLY])
 
      Check if the type exists and determine its size.  On return,
      "HAVE_${VARIABLE}" holds the existence of the type, and "${VARIABLE}"
      holds one of the following:
 
          <size> = type has non-zero size <size>
          "0"    = type has arch-dependent size (see below)
          ""    = type does not exist
 
      Furthermore, the variable "${VARIABLE}_CODE" holds C preprocessor code
      to define the macro "${VARIABLE}" to the size of the type, or leave
      the macro undefined if the type does not exist.
 
      The variable "${VARIABLE}" may be "0" when CMAKE_OSX_ARCHITECTURES has
      multiple architectures for building OS X universal binaries.  This
      indicates that the type size varies across architectures.  In this
      case "${VARIABLE}_CODE" contains C preprocessor tests mapping from
      each architecture macro to the corresponding type size.  The list of
      architecture macros is stored in "${VARIABLE}_KEYS", and the value for
      each key is stored in "${VARIABLE}-${KEY}".
 
      If the BUILTIN_TYPES_ONLY option is not given, the macro checks for
      headers <sys/types.h>, <stdint.h>, and <stddef.h>, and saves results
      in HAVE_SYS_TYPES_H, HAVE_STDINT_H, and HAVE_STDDEF_H.  The type size
      check automatically includes the available headers, thus supporting
      checks of types defined in the headers.
 
      Despite the name of the macro you may use it to check the size of more
      complex expressions, too.  To check e.g.  for the size of a struct
      member you can do something like this:
 
        check_type_size("((struct something*)0)->member" SIZEOF_MEMBER)
 
     
 
      The following variables may be set before calling this macro to modify
      the way the check is run:
 
        CMAKE_REQUIRED_FLAGS = string of compile command line flags
        CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
        CMAKE_REQUIRED_INCLUDES = list of include directories
        CMAKE_REQUIRED_LIBRARIES = list of libraries to link
        CMAKE_EXTRA_INCLUDE_FILES = list of extra headers to include
 
 
  CheckVariableExists
      Check if the variable exists.
 
        CHECK_VARIABLE_EXISTS(VAR VARIABLE)
 
     
 
        VAR      - the name of the variable
        VARIABLE - variable to store the result
 
     
 
      This macro is only for C variables.
 
      The following variables may be set before calling this macro to modify
      the way the check is run:
 
        CMAKE_REQUIRED_FLAGS = string of compile command line flags
        CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
        CMAKE_REQUIRED_LIBRARIES = list of libraries to link
 
 
  Dart
      Configure a project for testing with CTest or old Dart Tcl Client
 
      This file is the backwards-compatibility version of the CTest module.
      It supports using the old Dart 1 Tcl client for driving dashboard
      submissions as well as testing with CTest.  This module should be
      included in the CMakeLists.txt file at the top of a project.  Typical
      usage:
 
        include(Dart)
        if(BUILD_TESTING)
          # ... testing related CMake code ...
        endif()
 
      The BUILD_TESTING option is created by the Dart module to determine
      whether testing support should be enabled.  The default is ON.
 
  DeployQt4
      Functions to help assemble a standalone Qt4 executable.
 
      A collection of CMake utility functions useful for deploying Qt4
      executables.
 
      The following functions are provided by this module:
 
          write_qt4_conf
          resolve_qt4_paths
          fixup_qt4_executable
          install_qt4_plugin_path
          install_qt4_plugin
          install_qt4_executable
 
      Requires CMake 2.6 or greater because it uses function and
      PARENT_SCOPE.  Also depends on BundleUtilities.cmake.
 
        WRITE_QT4_CONF(<qt_conf_dir> <qt_conf_contents>)
 
      Writes a qt.conf file with the <qt_conf_contents> into <qt_conf_dir>.
 
        RESOLVE_QT4_PATHS(<paths_var> [<executable_path>])
 
      Loop through <paths_var> list and if any don't exist resolve them
      relative to the <executable_path> (if supplied) or the
      CMAKE_INSTALL_PREFIX.
 
        FIXUP_QT4_EXECUTABLE(<executable> [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf>])
 
      Copies Qt plugins, writes a Qt configuration file (if needed) and
      fixes up a Qt4 executable using BundleUtilities so it is standalone
      and can be drag-and-drop copied to another machine as long as all of
      the system libraries are compatible.
 
      <executable> should point to the executable to be fixed-up.
 
      <qtplugins> should contain a list of the names or paths of any Qt
      plugins to be installed.
 
      <libs> will be passed to BundleUtilities and should be a list of any
      already installed plugins, libraries or executables to also be
      fixed-up.
 
      <dirs> will be passed to BundleUtilities and should contain and
      directories to be searched to find library dependencies.
 
      <plugins_dir> allows an custom plugins directory to be used.
 
      <request_qt_conf> will force a qt.conf file to be written even if not
      needed.
 
        INSTALL_QT4_PLUGIN_PATH(plugin executable copy installed_plugin_path_var <plugins_dir> <component> <configurations>)
 
      Install (or copy) a resolved <plugin> to the default plugins directory
      (or <plugins_dir>) relative to <executable> and store the result in
      <installed_plugin_path_var>.
 
      If <copy> is set to TRUE then the plugins will be copied rather than
      installed.  This is to allow this module to be used at CMake time
      rather than install time.
 
      If <component> is set then anything installed will use this COMPONENT.
 
        INSTALL_QT4_PLUGIN(plugin executable copy installed_plugin_path_var <plugins_dir> <component>)
 
      Install (or copy) an unresolved <plugin> to the default plugins
      directory (or <plugins_dir>) relative to <executable> and store the
      result in <installed_plugin_path_var>.  See documentation of
      INSTALL_QT4_PLUGIN_PATH.
 
        INSTALL_QT4_EXECUTABLE(<executable> [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf> <component>])
 
      Installs Qt plugins, writes a Qt configuration file (if needed) and
      fixes up a Qt4 executable using BundleUtilities so it is standalone
      and can be drag-and-drop copied to another machine as long as all of
      the system libraries are compatible.  The executable will be fixed-up
      at install time.  <component> is the COMPONENT used for bundle fixup
      and plugin installation.  See documentation of FIXUP_QT4_BUNDLE.

  ExternalProject
      Create custom targets to build projects in external trees
 
      The 'ExternalProject_Add' function creates a custom target to drive
      download, update/patch, configure, build, install and test steps of an
      external project:
 
        ExternalProject_Add(<name>    # Name for custom target

          [LOG_CONFIGURE 1]          # Wrap configure in script to log output
          [LOG_BUILD 1]              # Wrap build in script to log output
          [LOG_TEST 1]                # Wrap test in script to log output

          #--Custom targets-------------
          [STEP_TARGETS st1 st2 ...]  # Generate custom targets for these steps
          )
 
      The *_DIR options specify directories for the project, with default
      directories computed as follows.  If the PREFIX option is given to
      ExternalProject_Add() or the EP_PREFIX directory property is set, then
      an external project is built and installed under the specified prefix:
 
          TMP_DIR      = <prefix>/tmp
          STAMP_DIR    = <prefix>/src/<name>-stamp
          DOWNLOAD_DIR = <prefix>/src
          SOURCE_DIR  = <prefix>/src/<name>
          BINARY_DIR  = <prefix>/src/<name>-build
          INSTALL_DIR  = <prefix>
 
      Otherwise, if the EP_BASE directory property is set then components of
      an external project are stored under the specified base:
 
          TMP_DIR      = <base>/tmp/<name>
          STAMP_DIR    = <base>/Stamp/<name>
          DOWNLOAD_DIR = <base>/Download/<name>
          SOURCE_DIR  = <base>/Source/<name>
          BINARY_DIR  = <base>/Build/<name>
          INSTALL_DIR  = <base>/Install/<name>
 
      If no PREFIX, EP_PREFIX, or EP_BASE is specified then the default is
      to set PREFIX to "<name>-prefix".  Relative paths are interpreted with
      respect to the build directory corresponding to the source directory
      in which ExternalProject_Add is invoked.
 
      If SOURCE_DIR is explicitly set to an existing directory the project
      will be built from it.  Otherwise a download step must be specified
      using one of the DOWNLOAD_COMMAND, CVS_*, SVN_*, or URL options.  The
      URL option may refer locally to a directory or source tarball, or
      refer to a remote tarball (e.g.  http://.../src.tgz).
 
      The 'ExternalProject_Add_Step' function adds a custom step to an
      external project:
 
        ExternalProject_Add_Step(<name> <step> # Names of project and custom step
          [COMMAND cmd...]        # Command line invoked by this step
          [COMMENT "text..."]    # Text printed when step executes
          [DEPENDEES steps...]    # Steps on which this step depends
          [DEPENDERS steps...]    # Steps that depend on this step
          [DEPENDS files...]      # Files on which this step depends
          [ALWAYS 1]              # No stamp file, step always runs
          [WORKING_DIRECTORY dir] # Working directory for command
          [LOG 1]                # Wrap step in script to log output
          )
 
      The command line, comment, and working directory of every standard and
      custom step is processed to replace tokens <SOURCE_DIR>, <BINARY_DIR>,
      <INSTALL_DIR>, and <TMP_DIR> with corresponding property values.
 
      The 'ExternalProject_Get_Property' function retrieves external project
      target properties:
 
        ExternalProject_Get_Property(<name> [prop1 [prop2 [...]]])
 
      It stores property values in variables of the same name.  Property
      names correspond to the keyword argument names of
      'ExternalProject_Add'.
 
      The 'ExternalProject_Add_StepTargets' function generates custom
      targets for the steps listed:
 
        ExternalProject_Add_StepTargets(<name> [step1 [step2 [...]]])
 
     
 
      If STEP_TARGETS is set then ExternalProject_Add_StepTargets is
      automatically called at the end of matching calls to
      ExternalProject_Add_Step.  Pass STEP_TARGETS explicitly to individual
      ExternalProject_Add calls, or implicitly to all ExternalProject_Add
      calls by setting the directory property EP_STEP_TARGETS.
 
      If STEP_TARGETS is not set, clients may still manually call
      ExternalProject_Add_StepTargets after calling ExternalProject_Add or
      ExternalProject_Add_Step.
 
      This functionality is provided to make it easy to drive the steps
      independently of each other by specifying targets on build command
      lines.  For example, you may be submitting to a sub-project based
      dashboard, where you want to drive the configure portion of the build,
      then submit to the dashboard, followed by the build portion, followed
      by tests.  If you invoke a custom target that depends on a step
      halfway through the step dependency chain, then all the previous steps
      will also run to ensure everything is up to date.
 
      For example, to drive configure, build and test steps independently
      for each ExternalProject_Add call in your project, write the following
      line prior to any ExternalProject_Add calls in your CMakeLists file:
 
          set_property(DIRECTORY PROPERTY EP_STEP_TARGETS configure build test)
 
 
  FeatureSummary
      Macros for generating a summary of enabled/disabled features
 
     
 
      This module provides the macros feature_summary(),
      set_package_properties() and add_feature_info().  For compatibility it
      also still provides set_package_info(), set_feature_info(),
      print_enabled_features() and print_disabled_features().
 
      These macros can be used to generate a summary of enabled and disabled
      packages and/or feature for a build tree:
 
          -- The following OPTIONAL packages have been found:
          LibXml2 (required version >= 2.4) , XML processing library. , <http://xmlsoft.org>

                            [DESCRIPTION "Found packages:"]
                            WHAT (ALL | PACKAGES_FOUND | PACKAGES_NOT_FOUND
                                | ENABLED_FEATURES | DISABLED_FEATURES]
                          )
 
     
 
      The FEATURE_SUMMARY() macro can be used to print information about
      enabled or disabled packages or features of a project.  By default,
      only the names of the features/packages will be printed and their
      required version when one was specified.  Use SET_PACKAGE_PROPERTIES()
      to add more useful information, like e.g.  a download URL for the
      respective package or their purpose in the project.
 
      The WHAT option is the only mandatory option.  Here you specify what
      information will be printed:
 
          ALL: print everything
          ENABLED_FEATURES: the list of all features which are enabled
          DISABLED_FEATURES: the list of all features which are disabled
          PACKAGES_FOUND: the list of all packages which have been found
          PACKAGES_NOT_FOUND: the list of all packages which have not been found
          OPTIONAL_PACKAGES_FOUND: only those packages which have been found which have the type OPTIONAL
          OPTIONAL_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type OPTIONAL
          RECOMMENDED_PACKAGES_FOUND: only those packages which have been found which have the type RECOMMENDED
          RECOMMENDED_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type RECOMMENDED
          REQUIRED_PACKAGES_FOUND: only those packages which have been found which have the type REQUIRED
          REQUIRED_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type REQUIRED
          RUNTIME_PACKAGES_FOUND: only those packages which have been found which have the type RUNTIME
          RUNTIME_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type RUNTIME
 
     
 
      If a FILENAME is given, the information is printed into this file.  If
      APPEND is used, it is appended to this file, otherwise the file is
      overwritten if it already existed.  If the VAR option is used, the
      information is "printed" into the specified variable.  If FILENAME is
      not used, the information is printed to the terminal.  Using the
      DESCRIPTION option a description or headline can be set which will be
      printed above the actual content.  If INCLUDE_QUIET_PACKAGES is given,
      packages which have been searched with find_package(...  QUIET) will
      also be listed.  By default they are skipped.  If
      FATAL_ON_MISSING_REQUIRED_PACKAGES is given, CMake will abort if a
      package which is marked as REQUIRED has not been found.
 
      Example 1, append everything to a file:
 
          feature_summary(WHAT ALL
                          FILENAME ${CMAKE_BINARY_DIR}/all.log APPEND)
 
     
 
      Example 2, print the enabled features into the variable
      enabledFeaturesText, including QUIET packages:
 
          feature_summary(WHAT ENABLED_FEATURES
                          INCLUDE_QUIET_PACKAGES
                          DESCRIPTION "Enabled Features:"
                          VAR enabledFeaturesText)
          message(STATUS "${enabledFeaturesText}")
 
     
 
     
 
          SET_PACKAGE_PROPERTIES(<name> PROPERTIES [ URL <url> ]
                                                    [ DESCRIPTION <description> ]
                                                    [ TYPE (RUNTIME|OPTIONAL|RECOMMENDED|REQUIRED) ]
                                                    [ PURPOSE <purpose> ]
                                )
 
     
 
      Use this macro to set up information about the named package, which
      can then be displayed via FEATURE_SUMMARY().  This can be done either
      directly in the Find-module or in the project which uses the module
      after the find_package() call.  The features for which information can
      be set are added automatically by the find_package() command.
 
      URL: this should be the homepage of the package, or something similar.
      Ideally this is set already directly in the Find-module.
 
      DESCRIPTION: A short description what that package is, at most one
      sentence.  Ideally this is set already directly in the Find-module.
 
      TYPE: What type of dependency has the using project on that package.
      Default is OPTIONAL.  In this case it is a package which can be used
      by the project when available at buildtime, but it also work without.
      RECOMMENDED is similar to OPTIONAL, i.e.  the project will build if
      the package is not present, but the functionality of the resulting
      binaries will be severly limited.  If a REQUIRED package is not
      available at buildtime, the project may not even build.  This can be
      combined with the FATAL_ON_MISSING_REQUIRED_PACKAGES argument for
      feature_summary().  Last, a RUNTIME package is a package which is
      actually not used at all during the build, but which is required for
      actually running the resulting binaries.  So if such a package is
      missing, the project can still be built, but it may not work later on.
      If set_package_properties() is called multiple times for the same
      package with different TYPEs, the TYPE is only changed to higher TYPEs
      ( RUNTIME < OPTIONAL < RECOMMENDED < REQUIRED ), lower TYPEs are
      ignored.  The TYPE property is project-specific, so it cannot be set
      by the Find-module, but must be set in the project.
 
      PURPOSE: This describes which features this package enables in the
      project, i.e.  it tells the user what functionality he gets in the
      resulting binaries.  If set_package_properties() is called multiple
      times for a package, all PURPOSE properties are appended to a list of
      purposes of the package in the project.  As the TYPE property, also
      the PURPOSE property is project-specific, so it cannot be set by the
      Find-module, but must be set in the project.
 
     
 
      Example for setting the info for a package:
 
          find_package(LibXml2)
          set_package_properties(LibXml2 PROPERTIES DESCRIPTION "A XML processing library."
                                                    URL "http://xmlsoft.org/")
 
     
 
          set_package_properties(LibXml2 PROPERTIES TYPE RECOMMENDED
                                                    PURPOSE "Enables HTML-import in MyWordProcessor")
          ...
          set_package_properties(LibXml2 PROPERTIES TYPE OPTIONAL
                                                    PURPOSE "Enables odt-export in MyWordProcessor")
 
     
 
          find_package(DBUS)
          set_package_properties(DBUS PROPERTIES TYPE RUNTIME
                                                    PURPOSE "Necessary to disable the screensaver during a presentation" )
 
     
 
          ADD_FEATURE_INFO(<name> <enabled> <description>)
 
      Use this macro to add information about a feature with the given
      <name>.  <enabled> contains whether this feature is enabled or not,
      <description> is a text describing the feature.  The information can
      be displayed using feature_summary() for ENABLED_FEATURES and
      DISABLED_FEATURES respectively.
 
      Example for setting the info for a feature:
 
          option(WITH_FOO "Help for foo" ON)
          add_feature_info(Foo WITH_FOO "The Foo feature provides very cool stuff.")
 
     
 
     
 
      The following macros are provided for compatibility with previous
      CMake versions:
 
          SET_PACKAGE_INFO(<name> <description> [<url> [<purpose>] ] )
 
      Use this macro to set up information about the named package, which
      can then be displayed via FEATURE_SUMMARY().  This can be done either
      directly in the Find-module or in the project which uses the module
      after the find_package() call.  The features for which information can
      be set are added automatically by the find_package() command.
 
          PRINT_ENABLED_FEATURES()
 
      Does the same as FEATURE_SUMMARY(WHAT ENABLED_FEATURES DESCRIPTION
      "Enabled features:")
 
          PRINT_DISABLED_FEATURES()
 
      Does the same as FEATURE_SUMMARY(WHAT DISABLED_FEATURES DESCRIPTION
      "Disabled features:")
 
          SET_FEATURE_INFO(<name> <description> [<url>] )
 
      Does the same as SET_PACKAGE_INFO(<name> <description> <url> )
 
  FindALSA
      Find alsa
 
      Find the alsa libraries (asound)
 
        This module defines the following variables:
            ALSA_FOUND      - True if ALSA_INCLUDE_DIR & ALSA_LIBRARY are found
            ALSA_LIBRARIES  - Set when ALSA_LIBRARY is found
            ALSA_INCLUDE_DIRS - Set when ALSA_INCLUDE_DIR is found
 
     
 
            ALSA_INCLUDE_DIR - where to find asoundlib.h, etc.

            ALSA_VERSION_STRING - the version of alsa found (since CMake 2.8.8)
 
     
 
 
  FindASPELL
      Try to find ASPELL
 
      Once done this will define
 
        ASPELL_FOUND - system has ASPELL

        ASPELL_LIBRARIES - The libraries needed to use ASPELL
        ASPELL_DEFINITIONS - Compiler switches required for using ASPELL
 
 
  FindAVIFile
      Locate AVIFILE library and include paths
 
      AVIFILE (http://avifile.sourceforge.net/)is a set of libraries for
      i386 machines to use various AVI codecs.  Support is limited beyond
      Linux.  Windows provides native AVI support, and so doesn't need this
      library.  This module defines
 
        AVIFILE_INCLUDE_DIR, where to find avifile.h , etc.
        AVIFILE_LIBRARIES, the libraries to link against
        AVIFILE_DEFINITIONS, definitions to use when compiling
        AVIFILE_FOUND, If false, don't try to use AVIFILE
 
 
  FindArmadillo
      Find Armadillo
 
      Find the Armadillo C++ library
 
      Using Armadillo:
 
        find_package(Armadillo REQUIRED)
        include_directories(${ARMADILLO_INCLUDE_DIRS})
        add_executable(foo foo.cc)
        target_link_libraries(foo ${ARMADILLO_LIBRARIES})
 
      This module sets the following variables:
 
        ARMADILLO_FOUND - set to true if the library is found
        ARMADILLO_INCLUDE_DIRS - list of required include directories
        ARMADILLO_LIBRARIES - list of libraries to be linked

        ARMADILLO_VERSION_PATCH - patch version number
        ARMADILLO_VERSION_STRING - version number as a string (ex: "1.0.4")
        ARMADILLO_VERSION_NAME - name of the version (ex: "Antipodean Antileech")
 
 
  FindBISON
      Find bison executable and provides macros to generate custom build
      rules
 
      The module defines the following variables:
 
        BISON_EXECUTABLE - path to the bison program
        BISON_VERSION - version of bison
        BISON_FOUND - true if the program was found
 
     
 
      The minimum required version of bison can be specified using the
      standard CMake syntax, e.g.  find_package(BISON 2.1.3)
 
      If bison is found, the module defines the macros:
 
        BISON_TARGET(<Name> <YaccInput> <CodeOutput> [VERBOSE <file>]
                    [COMPILE_FLAGS <string>])
 
      which will create a custom rule to generate a parser.  <YaccInput> is
      the path to a yacc file.  <CodeOutput> is the name of the source file
      generated by bison.  A header file is also be generated, and contains
      the token list.  If COMPILE_FLAGS option is specified, the next
      parameter is added in the bison command line.  if VERBOSE option is
      specified, <file> is created and contains verbose descriptions of the
      grammar and parser.  The macro defines a set of variables:
 
        BISON_${Name}_DEFINED - true is the macro ran successfully
        BISON_${Name}_INPUT - The input source file, an alias for <YaccInput>
        BISON_${Name}_OUTPUT_SOURCE - The source file generated by bison
        BISON_${Name}_OUTPUT_HEADER - The header file generated by bison
        BISON_${Name}_OUTPUTS - The sources files generated by bison
        BISON_${Name}_COMPILE_FLAGS - Options used in the bison command line
 
     
 
        ====================================================================
        Example:
 
     
 
          find_package(BISON)
          BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
          add_executable(Foo main.cpp ${BISON_MyParser_OUTPUTS})
        ====================================================================
 
 
  FindBLAS
      Find BLAS library
 
      This module finds an installed fortran library that implements the
      BLAS linear-algebra interface (see http://www.netlib.org/blas/).  The
      list of libraries searched for is taken from the autoconf macro file,
      acx_blas.m4 (distributed at
      http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).
 
      This module sets the following variables:
 
        BLAS_FOUND - set to true if a library implementing the BLAS interface
          is found
        BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
          and -L).
        BLAS_LIBRARIES - uncached list of libraries (using full path name) to
          link against to use BLAS
        BLAS95_LIBRARIES - uncached list of libraries (using full path name)
          to link against to use BLAS95 interface
        BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
          is found
        BLA_STATIC  if set on this determines what kind of linkage we do (static)
        BLA_VENDOR  if set checks only the specified vendor, if not set checks
            all the possibilities
        BLA_F95    if set on tries to find the f95 interfaces for BLAS/LAPACK
 
      C/CXX should be enabled to use Intel mkl
 
  FindBZip2
      Try to find BZip2
 
      Once done this will define
 
        BZIP2_FOUND - system has BZip2
        BZIP2_INCLUDE_DIR - the BZip2 include directory
        BZIP2_LIBRARIES - Link these to use BZip2
        BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_
        BZIP2_VERSION_STRING - the version of BZip2 found (since CMake 2.8.8)
 
 
  FindBoost
      Try to find Boost include dirs and libraries
 
      Usage of this module as follows:
 
      NOTE: Take note of the Boost_ADDITIONAL_VERSIONS variable below.  Due
      to Boost naming conventions and limitations in CMake this find module
      is NOT future safe with respect to Boost version numbers, and may
      break.
 
      == Using Header-Only libraries from within Boost: ==
 
          find_package( Boost 1.36.0 )
          if(Boost_FOUND)
            include_directories(${Boost_INCLUDE_DIRS})
            add_executable(foo foo.cc)
          endif()
 
     
 
     
 
      == Using actual libraries from within Boost: ==
 
          set(Boost_USE_STATIC_LIBS        ON)
          set(Boost_USE_MULTITHREADED      ON)
          set(Boost_USE_STATIC_RUNTIME    OFF)
          find_package( Boost 1.36.0 COMPONENTS date_time filesystem system ... )
 
     
 
          if(Boost_FOUND)
            include_directories(${Boost_INCLUDE_DIRS})
            add_executable(foo foo.cc)
            target_link_libraries(foo ${Boost_LIBRARIES})
          endif()
 
     
 
     
 
      The components list needs to contain actual names of boost libraries
      only, such as "date_time" for "libboost_date_time".  If you're using
      parts of Boost that contain header files only (e.g.  foreach) you do
      not need to specify COMPONENTS.
 
      You should provide a minimum version number that should be used.  If
      you provide this version number and specify the REQUIRED attribute,
      this module will fail if it can't find the specified or a later
      version.  If you specify a version number this is automatically put
      into the considered list of version numbers and thus doesn't need to
      be specified in the Boost_ADDITIONAL_VERSIONS variable (see below).
 
      NOTE for Visual Studio Users:
 
            Automatic linking is used on MSVC & Borland compilers by default when
            #including things in Boost.  It's important to note that setting
            Boost_USE_STATIC_LIBS to OFF is NOT enough to get you dynamic linking,
            should you need this feature.  Automatic linking typically uses static
            libraries with a few exceptions (Boost.Python is one).
 
     
 
            Please see the section below near Boost_LIB_DIAGNOSTIC_DEFINITIONS for
            more details.  Adding a target_link_libraries() as shown in the example
            above appears to cause VS to link dynamically if Boost_USE_STATIC_LIBS
            gets set to OFF.  It is suggested you avoid automatic linking since it
            will make your application less portable.
 
     
 
      =========== The mess that is Boost_ADDITIONAL_VERSIONS (sorry?)
      ============
 
      OK, so the Boost_ADDITIONAL_VERSIONS variable can be used to specify a
      list of boost version numbers that should be taken into account when
      searching for Boost.  Unfortunately boost puts the version number into
      the actual filename for the libraries, so this variable will certainly
      be needed in the future when new Boost versions are released.
 
      Currently this module searches for the following version numbers:
      1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1, 1.35, 1.35.0, 1.35.1,
      1.36, 1.36.0, 1.36.1, 1.37, 1.37.0, 1.38, 1.38.0, 1.39, 1.39.0, 1.40,
      1.40.0, 1.41, 1.41.0, 1.42, 1.42.0, 1.43, 1.43.0, 1.44, 1.44.0, 1.45,
      1.45.0, 1.46, 1.46.0, 1.46.1, 1.47, 1.47.0, 1.48, 1.48.0, 1.49,
      1.49.0, 1.50, 1.50.0, 1.51, 1.51.0, 1.52, 1.52.0, 1.53, 1.53.0, 1.54,
      1.54.0, 1.55, 1.55.0, 1.56, 1.56.0
 
      NOTE: If you add a new major 1.x version in Boost_ADDITIONAL_VERSIONS
      you should add both 1.x and 1.x.0 as shown above.  Official Boost
      include directories omit the 3rd version number from include paths if
      it is 0 although not all binary Boost releases do so.
 
      set(Boost_ADDITIONAL_VERSIONS "1.78" "1.78.0" "1.79" "1.79.0")
 
      ===================================== =============
      ========================
 
      Variables used by this module, they can change the default behaviour
      and need to be set before calling find_package:
 
          Boost_USE_MULTITHREADED      Can be set to OFF to use the non-multithreaded
                                      boost libraries.  If not specified, defaults
                                      to ON.
 
     
 
          Boost_USE_STATIC_LIBS        Can be set to ON to force the use of the static
                                      boost libraries. Defaults to OFF.
 
     
 
          Boost_NO_SYSTEM_PATHS        Set to TRUE to suppress searching in system
                                      paths (or other locations outside of BOOST_ROOT
                                      or BOOST_INCLUDEDIR).  Useful when specifying
                                      BOOST_ROOT. Defaults to OFF.
                                        [Since CMake 2.8.3]
 
     
 
          Boost_NO_BOOST_CMAKE        Do not do a find_package call in config mode
                                      before searching for a regular boost install.
                                      This will avoid finding boost-cmake installs.
                                      Defaults to OFF.
                                        [Since CMake 2.8.6]
 
     
 
          Boost_USE_STATIC_RUNTIME    If enabled, searches for boost libraries
                                      linked against a static C++ standard library
                                      ('s' ABI tag). This option should be set to
                                      ON or OFF because the default behavior
                                      if not specified is platform dependent
                                      for backwards compatibility.
                                        [Since CMake 2.8.3]
 
     
 
          Boost_USE_DEBUG_PYTHON      If enabled, searches for boost libraries
                                      compiled against a special debug build of
                                      Python ('y' ABI tag). Defaults to OFF.
                                        [Since CMake 2.8.3]
 
     
 
          Boost_USE_STLPORT            If enabled, searches for boost libraries
                                      compiled against the STLPort standard
                                      library ('p' ABI tag). Defaults to OFF.
                                        [Since CMake 2.8.3]
 
     
 
          Boost_USE_STLPORT_DEPRECATED_NATIVE_IOSTREAMS
                                      If enabled, searches for boost libraries
                                      compiled against the deprecated STLPort
                                      "native iostreams" feature ('n' ABI tag).
                                      Defaults to OFF.
                                        [Since CMake 2.8.3]
 
     
 
      Other Variables used by this module which you may want to set.
 
          Boost_ADDITIONAL_VERSIONS    A list of version numbers to use for searching
                                      the boost include directory.  Please see
                                      the documentation above regarding this
                                      annoying, but necessary variable :(
 
     
 
          Boost_DEBUG                  Set this to TRUE to enable debugging output
                                      of FindBoost.cmake if you are having problems.
                                      Please enable this before filing any bug
                                      reports.
 
     
 
          Boost_DETAILED_FAILURE_MSG  FindBoost doesn't output detailed information
                                      about why it failed or how to fix the problem
                                      unless this is set to TRUE or the REQUIRED
                                      keyword is specified in find_package().
                                        [Since CMake 2.8.0]
 
     
 
          Boost_COMPILER              Set this to the compiler suffix used by Boost
                                      (e.g. "-gcc43") if FindBoost has problems finding
                                      the proper Boost installation
 
     
 
          Boost_THREADAPI                When building boost.thread, sometimes the name of the
                                      library contains an additional "pthread" or "win32"
                                      string known as the threadapi.  This can happen when
                                      compiling against pthreads on Windows or win32 threads
                                      on Cygwin.  You may specify this variable and if set
                                      when FindBoost searches for the Boost threading library
                                      it will first try to match the threadapi you specify.
                                        For Example: libboost_thread_win32-mgw45-mt-1_43.a
                                      might be found if you specified "win32" here before
                                      falling back on libboost_thread-mgw45-mt-1_43.a.
                                        [Since CMake 2.8.3]
 
     
 
          Boost_REALPATH              Resolves symbolic links for discovered boost libraries
                                      to assist with packaging.  For example, instead of
                                      Boost_SYSTEM_LIBRARY_RELEASE being resolved to
                                      "/usr/lib/libboost_system.so" it would be
                                      "/usr/lib/libboost_system.so.1.42.0" instead.
                                      This does not affect linking and should not be
                                      enabled unless the user needs this information.

  FindBullet
      Try to find the Bullet physics engine
 
     
 
        This module defines the following variables
 
     
 
        BULLET_FOUND - Was bullet found
        BULLET_INCLUDE_DIRS - the Bullet include directories
        BULLET_LIBRARIES - Link to this, by default it includes
                            all bullet components (Dynamics,
                            Collision, LinearMath, & SoftBody)
 
     
 
        This module accepts the following variables
 
     
 
        BULLET_ROOT - Can be set to bullet install path or Windows build path
 
     
 
 
  FindCABLE
      Find CABLE
 
      This module finds if CABLE is installed and determines where the
      include files and libraries are.  This code sets the following
      variables:
 
        CABLE            the path to the cable executable
        CABLE_TCL_LIBRARY the path to the Tcl wrapper library
        CABLE_INCLUDE_DIR the path to the include directory
 
     
 
      To build Tcl wrappers, you should add shared library and link it to
      ${CABLE_TCL_LIBRARY}.  You should also add ${CABLE_INCLUDE_DIR} as an
      include directory.
 
  FindCUDA
      Tools for building CUDA C files: libraries and build dependencies.
 
      This script locates the NVIDIA CUDA C tools.  It should work on linux,
      windows, and mac and should be reasonably up to date with CUDA C
      releases.
 
      This script makes use of the standard find_package arguments of
      <VERSION>, REQUIRED and QUIET.  CUDA_FOUND will report if an
      acceptable version of CUDA was found.
 
      The script will prompt the user to specify CUDA_TOOLKIT_ROOT_DIR if
      the prefix cannot be determined by the location of nvcc in the system
      path and REQUIRED is specified to find_package().  To use a different
      installed version of the toolkit set the environment variable
      CUDA_BIN_PATH before running cmake (e.g.
      CUDA_BIN_PATH=/usr/local/cuda1.0 instead of the default
      /usr/local/cuda) or set CUDA_TOOLKIT_ROOT_DIR after configuring.  If
      you change the value of CUDA_TOOLKIT_ROOT_DIR, various components that
      depend on the path will be relocated.
 
      It might be necessary to set CUDA_TOOLKIT_ROOT_DIR manually on certain
      platforms, or to use a cuda runtime not installed in the default
      location.  In newer versions of the toolkit the cuda library is
      included with the graphics driver- be sure that the driver version
      matches what is needed by the cuda runtime version.
 
      The following variables affect the behavior of the macros in the
      script (in alphebetical order).  Note that any of these flags can be
      changed multiple times in the same directory before calling
      CUDA_ADD_EXECUTABLE, CUDA_ADD_LIBRARY, CUDA_COMPILE, CUDA_COMPILE_PTX
      or CUDA_WRAP_SRCS.
 
        CUDA_64_BIT_DEVICE_CODE (Default matches host bit size)
        -- Set to ON to compile for 64 bit device code, OFF for 32 bit device code.
            Note that making this different from the host code when generating object
            or C files from CUDA code just won't work, because size_t gets defined by
            nvcc in the generated source.  If you compile to PTX and then load the
            file yourself, you can mix bit sizes between device and host.
 
     
 
        CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON)
        -- Set to ON if you want the custom build rule to be attached to the source
            file in Visual Studio.  Turn OFF if you add the same cuda file to multiple
            targets.
 
     
 
            This allows the user to build the target from the CUDA file; however, bad
            things can happen if the CUDA source file is added to multiple targets.
            When performing parallel builds it is possible for the custom build
            command to be run more than once and in parallel causing cryptic build
            errors.  VS runs the rules for every source file in the target, and a
            source can have only one rule no matter how many projects it is added to.
            When the rule is run from multiple targets race conditions can occur on
            the generated file.  Eventually everything will get built, but if the user
            is unaware of this behavior, there may be confusion.  It would be nice if
            this script could detect the reuse of source files across multiple targets
            and turn the option off for the user, but no good solution could be found.
 
     
 
        CUDA_BUILD_CUBIN (Default OFF)
        -- Set to ON to enable and extra compilation pass with the -cubin option in
            Device mode. The output is parsed and register, shared memory usage is
            printed during build.
 
     
 
        CUDA_BUILD_EMULATION (Default OFF for device mode)
        -- Set to ON for Emulation mode. -D_DEVICEEMU is defined for CUDA C files
            when CUDA_BUILD_EMULATION is TRUE.
 
     
 
        CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR)
        -- Set to the path you wish to have the generated files placed.  If it is
            blank output files will be placed in CMAKE_CURRENT_BINARY_DIR.
            Intermediate files will always be placed in
            CMAKE_CURRENT_BINARY_DIR/CMakeFiles.
 
     
 
        CUDA_HOST_COMPILATION_CPP (Default ON)
        -- Set to OFF for C compilation of host code.
 
     
 
        CUDA_HOST_COMPILER (Default CMAKE_C_COMPILER, $(VCInstallDir)/bin for VS)
        -- Set the host compiler to be used by nvcc.  Ignored if -ccbin or
            --compiler-bindir is already present in the CUDA_NVCC_FLAGS or
            CUDA_NVCC_FLAGS_<CONFIG> variables.  For Visual Studio targets
            $(VCInstallDir)/bin is a special value that expands out to the path when
            the command is run from withing VS.
 
     
 
        CUDA_NVCC_FLAGS
        CUDA_NVCC_FLAGS_<CONFIG>
        -- Additional NVCC command line arguments.  NOTE: multiple arguments must be
            semi-colon delimited (e.g. --compiler-options;-Wall)
 
     
 
        CUDA_PROPAGATE_HOST_FLAGS (Default ON)
        -- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration
            dependent counterparts (e.g. CMAKE_C_FLAGS_DEBUG) automatically to the
            host compiler through nvcc's -Xcompiler flag.  This helps make the
            generated host code match the rest of the system better.  Sometimes
            certain flags give nvcc problems, and this will help you turn the flag
            propagation off.  This does not affect the flags supplied directly to nvcc
            via CUDA_NVCC_FLAGS or through the OPTION flags specified through
            CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS.  Flags used for
            shared library compilation are not affected by this flag.
 
     
 
        CUDA_VERBOSE_BUILD (Default OFF)
        -- Set to ON to see all the commands used when building the CUDA file.  When
            using a Makefile generator the value defaults to VERBOSE (run make
            VERBOSE=1 to see output), although setting CUDA_VERBOSE_BUILD to ON will
            always print the output.
 
     
 
      The script creates the following macros (in alphebetical order):
 
        CUDA_ADD_CUFFT_TO_TARGET( cuda_target )
        -- Adds the cufft library to the target (can be any target).  Handles whether
            you are in emulation mode or not.
 
     
 
        CUDA_ADD_CUBLAS_TO_TARGET( cuda_target )
        -- Adds the cublas library to the target (can be any target).  Handles
            whether you are in emulation mode or not.
 
     
 
        CUDA_ADD_EXECUTABLE( cuda_target file0 file1 ...
                              [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
        -- Creates an executable "cuda_target" which is made up of the files
            specified.  All of the non CUDA C files are compiled using the standard
            build rules specified by CMAKE and the cuda files are compiled to object
            files using nvcc and the host compiler.  In addition CUDA_INCLUDE_DIRS is
            added automatically to include_directories().  Some standard CMake target
            calls can be used on the target after calling this macro
            (e.g. set_target_properties and target_link_libraries), but setting
            properties that adjust compilation flags will not affect code compiled by
            nvcc.  Such flags should be modified before calling CUDA_ADD_EXECUTABLE,
            CUDA_ADD_LIBRARY or CUDA_WRAP_SRCS.
 
     
 
        CUDA_ADD_LIBRARY( cuda_target file0 file1 ...
                          [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
        -- Same as CUDA_ADD_EXECUTABLE except that a library is created.
 
     
 
        CUDA_BUILD_CLEAN_TARGET()
        -- Creates a convience target that deletes all the dependency files
            generated.  You should make clean after running this target to ensure the
            dependency files get regenerated.
 
     
 
        CUDA_COMPILE( generated_files file0 file1 ... [STATIC | SHARED | MODULE]
                      [OPTIONS ...] )
        -- Returns a list of generated files from the input source files to be used
            with ADD_LIBRARY or ADD_EXECUTABLE.
 
     
 
        CUDA_COMPILE_PTX( generated_files file0 file1 ... [OPTIONS ...] )
        -- Returns a list of PTX files generated from the input source files.
 
     
 
        CUDA_INCLUDE_DIRECTORIES( path0 path1 ... )
        -- Sets the directories that should be passed to nvcc
            (e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu
            files.
 
     
 
        CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ...
                          [STATIC | SHARED | MODULE] [OPTIONS ...] )
        -- This is where all the magic happens.  CUDA_ADD_EXECUTABLE,
            CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this
            function under the hood.
 
     
 
            Given the list of files (file0 file1 ... fileN) this macro generates
            custom commands that generate either PTX or linkable objects (use "PTX" or
            "OBJ" for the format argument to switch).  Files that don't end with .cu
            or have the HEADER_FILE_ONLY property are ignored.
 
     
 
            The arguments passed in after OPTIONS are extra command line options to
            give to nvcc.  You can also specify per configuration options by
            specifying the name of the configuration followed by the options.  General
            options must preceed configuration specific options.  Not all
            configurations need to be specified, only the ones provided will be used.
 
     
 
              OPTIONS -DFLAG=2 "-DFLAG_OTHER=space in flag"
              DEBUG -g
              RELEASE --use_fast_math
              RELWITHDEBINFO --use_fast_math;-g
              MINSIZEREL --use_fast_math
 
     
 
            For certain configurations (namely VS generating object files with
            CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will
            be produced for the given cuda file.  This is because when you add the
            cuda file to Visual Studio it knows that this file produces an object file
            and will link in the resulting object file automatically.
 
     
 
            This script will also generate a separate cmake script that is used at
            build time to invoke nvcc.  This is for several reasons.
 
     
 
              1. nvcc can return negative numbers as return values which confuses
              Visual Studio into thinking that the command succeeded.  The script now
              checks the error codes and produces errors when there was a problem.
 
     
 
              2. nvcc has been known to not delete incomplete results when it
              encounters problems.  This confuses build systems into thinking the
              target was generated when in fact an unusable file exists.  The script
              now deletes the output files if there was an error.
 
     
 
              3. By putting all the options that affect the build into a file and then
              make the build rule dependent on the file, the output files will be
              regenerated when the options change.
 
     
 
            This script also looks at optional arguments STATIC, SHARED, or MODULE to
            determine when to target the object compilation for a shared library.
            BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in
            CUDA_ADD_LIBRARY.  On some systems special flags are added for building
            objects intended for shared libraries.  A preprocessor macro,
            <target_name>_EXPORTS is defined when a shared library compilation is
            detected.
 
     
 
            Flags passed into add_definitions with -D or /D are passed along to nvcc.
 
     
 
      The script defines the following variables:
 
        CUDA_VERSION_MAJOR    -- The major version of cuda as reported by nvcc.
        CUDA_VERSION_MINOR    -- The minor version.
        CUDA_VERSION
        CUDA_VERSION_STRING  -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR
 
     
 
        CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set).
        CUDA_SDK_ROOT_DIR    -- Path to the CUDA SDK.  Use this to find files in the
                                  SDK.  This script will not directly support finding
                                  specific libraries or headers, as that isn't
                                  supported by NVIDIA.  If you want to change
                                  libraries when the path changes see the
                                  FindCUDA.cmake script for an example of how to clear
                                  these variables.  There are also examples of how to
                                  use the CUDA_SDK_ROOT_DIR to locate headers or
                                  libraries, if you so choose (at your own risk).
        CUDA_INCLUDE_DIRS    -- Include directory for cuda headers.  Added automatically
                                  for CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY.
        CUDA_LIBRARIES        -- Cuda RT library.
        CUDA_CUFFT_LIBRARIES  -- Device or emulation library for the Cuda FFT
                                  implementation (alternative to:

        CUDA_CUBLAS_LIBRARIES -- Device or emulation library for the Cuda BLAS
                                  implementation (alterative to:
                                  CUDA_ADD_CUBLAS_TO_TARGET macro).
        CUDA_curand_LIBRARY  -- CUDA Random Number Generation library.

              Valid only for CxxTest version 3.
 
     
 
              NOTE: In older versions of this Find Module,
              this variable controlled if the Python test
              generator was used instead of the Perl one,
              regardless of which scripting language the
              user had installed.
 
     
 
          CXXTEST_TESTGEN_ARGS (since CMake 2.8.3)
              Specify a list of options to pass to the CxxTest code
              generator.  If not defined, --error-printer is

          CXXTEST_ADD_TEST(<test_name> <gen_source_file> <input_files_to_testgen...>)
              Creates a CxxTest runner and adds it to the CTest testing suite
              Parameters:
                  test_name              The name of the test
                  gen_source_file        The generated source filename to be
                                          generated by CxxTest
                  input_files_to_testgen  The list of header files containing the
                                          CxxTest::TestSuite's to be included in
                                          this runner
 
     
 
              #==============
              Example Usage:
 
     
 
                  find_package(CxxTest)
                  if(CXXTEST_FOUND)
                      include_directories(${CXXTEST_INCLUDE_DIR})
                      enable_testing()
 
     
 
                      CXXTEST_ADD_TEST(unittest_foo foo_test.cc
                                        ${CMAKE_CURRENT_SOURCE_DIR}/foo_test.h)
                      target_link_libraries(unittest_foo foo) # as needed
                  endif()
 
     
 
                    This will (if CxxTest is found):
                    1. Invoke the testgen executable to autogenerate foo_test.cc in the
                        binary tree from "foo_test.h" in the current source directory.
                    2. Create an executable and test called unittest_foo.
 
     
 
            #=============
            Example foo_test.h:
 
     
 
                #include <cxxtest/TestSuite.h>
 
     
 
                class MyTestSuite : public CxxTest::TestSuite
                {
                public:
                    void testAddition( void )
                    {
                      TS_ASSERT( 1 + 1 > 1 );
                      TS_ASSERT_EQUALS( 1 + 1, 2 );

          IL_LIBRARIES -  the name of the IL library. These include the full path to
                          the core DevIL library. This one has to be linked into the
                          application.
          ILU_LIBRARIES -  the name of the ILU library. Again, the full path. This
                          library is for filters and effects, not actual loading. It
                          doesn't have to be linked if the functionality it provides
                          is not used.
          ILUT_LIBRARIES - the name of the ILUT library. Full path. This part of the
                          library interfaces with OpenGL. It is not strictly needed
                          in applications.
          IL_INCLUDE_DIR - where to find the il.h, ilu.h and ilut.h files.
          IL_FOUND -      this is set to TRUE if all the above variables were set.
                          This will be set to false if ILU or ILUT are not found,
                          even if they are not needed. In most systems, if one
                          library is found all the others are as well. That's the
                          way the DevIL developers release it.
 
 
  FindDoxygen
      This module looks for Doxygen and the path to Graphviz's dot
 
      Doxygen is a documentation generation tool.  Please see
      http://www.doxygen.org
 
      This module accepts the following optional variables:
 
          DOXYGEN_SKIP_DOT      = If true this module will skip trying to find Dot
                                  (an optional component often used by Doxygen)
 
     
 
      This modules defines the following variables:
 
          DOXYGEN_EXECUTABLE    = The path to the doxygen command.
          DOXYGEN_FOUND          = Was Doxygen found or not?
          DOXYGEN_VERSION        = The version reported by doxygen --version
 
     
 
          DOXYGEN_DOT_EXECUTABLE = The path to the dot program used by doxygen.
          DOXYGEN_DOT_FOUND      = Was Dot found or not?
          DOXYGEN_DOT_PATH      = The path to dot not including the executable
 
     
 
     
 
 
  FindEXPAT
      Find expat
 
      Find the native EXPAT headers and libraries.
 
        EXPAT_INCLUDE_DIRS - where to find expat.h, etc.
        EXPAT_LIBRARIES    - List of libraries when using expat.
        EXPAT_FOUND        - True if expat found.
 
 
  FindFLEX
      Find flex executable and provides a macro to generate custom build
      rules
 
     
 
      The module defines the following variables:
 
        FLEX_FOUND - true is flex executable is found
        FLEX_EXECUTABLE - the path to the flex executable
        FLEX_VERSION - the version of flex
        FLEX_LIBRARIES - The flex libraries
        FLEX_INCLUDE_DIRS - The path to the flex headers
 
     
 
      The minimum required version of flex can be specified using the
      standard syntax, e.g.  find_package(FLEX 2.5.13)
 
     
 
      If flex is found on the system, the module provides the macro:
 
        FLEX_TARGET(Name FlexInput FlexOutput [COMPILE_FLAGS <string>])
 
      which creates a custom command to generate the <FlexOutput> file from
      the <FlexInput> file.  If COMPILE_FLAGS option is specified, the next
      parameter is added to the flex command line.  Name is an alias used to
      get details of this custom command.  Indeed the macro defines the
      following variables:
 
        FLEX_${Name}_DEFINED - true is the macro ran successfully
        FLEX_${Name}_OUTPUTS - the source file generated by the custom rule, an
        alias for FlexOutput
        FLEX_${Name}_INPUT - the flex source file, an alias for ${FlexInput}
 
     
 
      Flex scanners oftenly use tokens defined by Bison: the code generated
      by Flex depends of the header generated by Bison.  This module also
      defines a macro:
 
        ADD_FLEX_BISON_DEPENDENCY(FlexTarget BisonTarget)
 
      which adds the required dependency between a scanner and a parser
      where <FlexTarget> and <BisonTarget> are the first parameters of
      respectively FLEX_TARGET and BISON_TARGET macros.
 
        ====================================================================
        Example:
 
     
 
          find_package(BISON)
          find_package(FLEX)
 
     
 
          BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
          FLEX_TARGET(MyScanner lexer.l  ${CMAKE_CURRENT_BINARY_DIR}/lexer.cpp)
          ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)
 
     
 
          include_directories(${CMAKE_CURRENT_BINARY_DIR})
          add_executable(Foo
            Foo.cc
            ${BISON_MyParser_OUTPUTS}
            ${FLEX_MyScanner_OUTPUTS}
          )

      If you would like each Google test to show up in CTest as a test you
      may use the following macro.  NOTE: It will slow down your tests by
      running an executable for each test and test fixture.  You will also
      have to rerun CMake after adding or removing tests or test fixtures.
 
      GTEST_ADD_TESTS(executable extra_args ARGN)

                        fixtures.
 
     
 
        Example:
            set(FooTestArgs --foo 1 --bar 2)
            add_executable(FooTest FooUnitTest.cc)
            GTEST_ADD_TESTS(FooTest "${FooTestArgs}" FooUnitTest.cc)

        GETTEXT_FOUND: True if gettext has been found.
        GETTEXT_VERSION_STRING: the version of gettext found (since CMake 2.8.8)
 
     
 
      Additionally it provides the following macros:
      GETTEXT_CREATE_TRANSLATIONS ( outputFile [ALL] file1 ...  fileN )
 
          This will create a target "translations" which will convert the
          given input po files into the binary output mo file. If the
          ALL option is used, the translations will also be created when
          building the default target.
 
      GETTEXT_PROCESS_POT( <potfile> [ALL] [INSTALL_DESTINATION <destdir>]
      LANGUAGES <lang1> <lang2> ...  )
 
            Process the given pot file to mo files.
            If INSTALL_DESTINATION is given then automatically install rules will be created,
            the language subdirectory will be taken into account (by default use share/locale/).
            If ALL is specified, the pot file is processed when building the all traget.
            It creates a custom target "potfile".
 
      GETTEXT_PROCESS_PO_FILES( <lang> [ALL] [INSTALL_DESTINATION <dir>]
      PO_FILES <po1> <po2> ...  )
 
            Process the given po files to mo files for the given language.
            If INSTALL_DESTINATION is given then automatically install rules will be created,
            the language subdirectory will be taken into account (by default use share/locale/).
            If ALL is specified, the po files are processed when building the all traget.
            It creates a custom target "pofiles".
 
 
  FindGit
       
 
      The module defines the following variables:
 
          GIT_EXECUTABLE - path to git command line client
          GIT_FOUND - true if the command line client was found
          GIT_VERSION_STRING - the version of git found (since CMake 2.8.8)
 
      Example usage:
 
          find_package(Git)
          if(GIT_FOUND)
            message("git found: ${GIT_EXECUTABLE}")
          endif()
 
 
  FindGnuTLS
      Try to find the GNU Transport Layer Security library (gnutls)

        GNUTLS_FOUND - System has gnutls
        GNUTLS_INCLUDE_DIR - The gnutls include directory
        GNUTLS_LIBRARIES - The libraries needed to use gnutls
        GNUTLS_DEFINITIONS - Compiler switches required for using gnutls

        GNUPLOT_VERSION_STRING - the version of Gnuplot found (since CMake 2.8.8)
 
     
 
      GNUPLOT_VERSION_STRING will not work for old versions like 3.7.1.
 
  FindHDF5
      Find HDF5, a library for reading and writing self describing array
      data.
 
     
 
      This module invokes the HDF5 wrapper compiler that should be installed
      alongside HDF5.  Depending upon the HDF5 Configuration, the wrapper
      compiler is called either h5cc or h5pcc.  If this succeeds, the module
      will then call the compiler with the -show argument to see what flags
      are used when compiling an HDF5 client application.
 
      The module will optionally accept the COMPONENTS argument.  If no
      COMPONENTS are specified, then the find module will default to finding
      only the HDF5 C library.  If one or more COMPONENTS are specified, the
      module will attempt to find the language bindings for the specified
      components.  The only valid components are C, CXX, Fortran, HL, and
      Fortran_HL.  If the COMPONENTS argument is not given, the module will
      attempt to find only the C bindings.
 
      On UNIX systems, this module will read the variable
      HDF5_USE_STATIC_LIBRARIES to determine whether or not to prefer a
      static link to a dynamic link for HDF5 and all of it's dependencies.
      To use this feature, make sure that the HDF5_USE_STATIC_LIBRARIES
      variable is set before the call to find_package.
 
      To provide the module with a hint about where to find your HDF5
      installation, you can set the environment variable HDF5_ROOT.  The
      Find module will then look in this path when searching for HDF5
      executables, paths, and libraries.
 
      In addition to finding the includes and libraries required to compile
      an HDF5 client application, this module also makes an effort to find
      tools that come with the HDF5 distribution that may be useful for
      regression testing.
 
      This module will define the following variables:
 
        HDF5_INCLUDE_DIRS - Location of the hdf5 includes
        HDF5_INCLUDE_DIR - Location of the hdf5 includes (deprecated)
        HDF5_DEFINITIONS - Required compiler definitions for HDF5
        HDF5_C_LIBRARIES - Required libraries for the HDF5 C bindings.
        HDF5_CXX_LIBRARIES - Required libraries for the HDF5 C++ bindings

            message("hg found: ${HG_EXECUTABLE}")
          endif()
 
 
  FindITK
      Find an ITK installation or build tree.
 
  FindImageMagick
      Find the ImageMagick binary suite.
 
      This module will search for a set of ImageMagick tools specified as
      components in the FIND_PACKAGE call.  Typical components include, but
      are not limited to (future versions of ImageMagick might have
      additional components not listed here):
 
        animate
        compare
        composite
        conjure
        convert
        display
        identify
        import
        mogrify
        montage
        stream
 
     
 
      If no component is specified in the FIND_PACKAGE call, then it only
      searches for the ImageMagick executable directory.  This code defines
      the following variables:
 
        ImageMagick_FOUND                  - TRUE if all components are found.
        ImageMagick_EXECUTABLE_DIR        - Full path to executables directory.

        ImageMagick_VERSION_STRING        - the version of ImageMagick found
                                              (since CMake 2.8.8)
 
     
 
      ImageMagick_VERSION_STRING will not work for old versions like 5.2.3.
 
      There are also components for the following ImageMagick APIs:
 
        Magick++
        MagickWand
        MagickCore
 
     
 
      For these components the following variables are set:

      QUIET, REQUIRED, etc.).
 
  FindJNI
      Find JNI java libraries.
 
      This module finds if Java is installed and determines where the

  FindMPI
      Find a Message Passing Interface (MPI) implementation
 
      The Message Passing Interface (MPI) is a library used to write
      high-performance distributed-memory parallel applications, and is
      typically deployed on a cluster.  MPI is a standard interface (defined
      by the MPI forum) for which many implementations are available.  All
      of them have somewhat different include paths, libraries to link
      against, etc., and this module tries to smooth out those differences.
 
      === Variables ===
 
      This module will set the following variables per language in your
      project, where <lang> is one of C, CXX, or Fortran:
 
          MPI_<lang>_FOUND          TRUE if FindMPI found MPI flags for <lang>
          MPI_<lang>_COMPILER        MPI Compiler wrapper for <lang>
          MPI_<lang>_COMPILE_FLAGS  Compilation flags for MPI programs
          MPI_<lang>_INCLUDE_PATH    Include path(s) for MPI header
          MPI_<lang>_LINK_FLAGS      Linking flags for MPI programs
          MPI_<lang>_LIBRARIES      All libraries to link MPI programs against
 
      Additionally, FindMPI sets the following variables for running MPI
      programs from the command line:
 
          MPIEXEC                    Executable for running MPI programs
          MPIEXEC_NUMPROC_FLAG      Flag to pass to MPIEXEC before giving
                                    it the number of processors to run on
          MPIEXEC_PREFLAGS          Flags to pass to MPIEXEC directly
                                    before the executable to run.
          MPIEXEC_POSTFLAGS          Flags to pass to MPIEXEC after other flags
 
      === Usage ===
 
      To use this module, simply call FindMPI from a CMakeLists.txt file, or
      run find_package(MPI), then run CMake.  If you are happy with the
      auto- detected configuration for your language, then you're done.  If
      not, you have two options:
 
          1. Set MPI_<lang>_COMPILER to the MPI wrapper (mpicc, etc.) of your
            choice and reconfigure.  FindMPI will attempt to determine all the
            necessary variables using THAT compiler's compile and link flags.
          2. If this fails, or if your MPI implementation does not come with
            a compiler wrapper, then set both MPI_<lang>_LIBRARIES and
            MPI_<lang>_INCLUDE_PATH.  You may also set any other variables
            listed above, but these two are required.  This will circumvent
            autodetection entirely.
 
      When configuration is successful, MPI_<lang>_COMPILER will be set to
      the compiler wrapper for <lang>, if it was found.  MPI_<lang>_FOUND
      and other variables above will be set if any MPI implementation was
      found for <lang>, regardless of whether a compiler was found.
 
      When using MPIEXEC to execute MPI applications, you should typically
      use all of the MPIEXEC flags as follows:
 
          ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS
            ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS
 
      where PROCS is the number of processors on which to execute the
      program, EXECUTABLE is the MPI program, and ARGS are the arguments to
      pass to the MPI program.
 
      === Backward Compatibility ===
 
      For backward compatibility with older versions of FindMPI, these
      variables are set, but deprecated:
 
          MPI_FOUND          MPI_COMPILER        MPI_LIBRARY
          MPI_COMPILE_FLAGS  MPI_INCLUDE_PATH    MPI_EXTRA_LIBRARY
          MPI_LINK_FLAGS      MPI_LIBRARIES
 
      In new projects, please use the MPI_<lang>_XXX equivalents.

  FindOpenSceneGraph
      Find OpenSceneGraph
 
      This module searches for the OpenSceneGraph core "osg" library as well
      as OpenThreads, and whatever additional COMPONENTS (nodekits) that you
      specify.
 
          See http://www.openscenegraph.org
 
     
 
      NOTE: To use this module effectively you must either require CMake >=
      2.6.3 with cmake_minimum_required(VERSION 2.6.3) or download and place
      FindOpenThreads.cmake, Findosg_functions.cmake, Findosg.cmake, and
      Find<etc>.cmake files into your CMAKE_MODULE_PATH.
 
      ==================================
 
      This module accepts the following variables (note mixed case)
 
          OpenSceneGraph_DEBUG - Enable debugging output
 
     
 
          OpenSceneGraph_MARK_AS_ADVANCED - Mark cache variables as advanced
                                            automatically
 
     
 
      The following environment variables are also respected for finding the
      OSG and it's various components.  CMAKE_PREFIX_PATH can also be used
      for this (see find_library() CMake documentation).
 
          <MODULE>_DIR (where MODULE is of the form "OSGVOLUME" and there is a FindosgVolume.cmake file)
          OSG_DIR
          OSGDIR
          OSG_ROOT
 
     
 
      [CMake 2.8.10]: The CMake variable OSG_DIR can now be used as well to
      influence detection, instead of needing to specify an environment
      variable.
 
      This module defines the following output variables:
 
          OPENSCENEGRAPH_FOUND - Was the OSG and all of the specified components found?
 
     
 
          OPENSCENEGRAPH_VERSION - The version of the OSG which was found
 
     
 
          OPENSCENEGRAPH_INCLUDE_DIRS - Where to find the headers
 
     
 
          OPENSCENEGRAPH_LIBRARIES - The OSG libraries
 
     
 
      ================================== Example Usage:
 
        find_package(OpenSceneGraph 2.0.0 REQUIRED osgDB osgUtil)
            # libOpenThreads & libosg automatically searched
        include_directories(${OPENSCENEGRAPH_INCLUDE_DIRS})
 
     
 
        add_executable(foo foo.cc)
        target_link_libraries(foo ${OPENSCENEGRAPH_LIBRARIES})
 
     
 
 
  FindOpenThreads
       
 
      OpenThreads is a C++ based threading library.  Its largest userbase
      seems to OpenSceneGraph so you might notice I accept OSGDIR as an
      environment path.  I consider this part of the Findosg* suite used to
      find OpenSceneGraph components.  Each component is separate and you
      must opt in to each module.
 
      Locate OpenThreads This module defines OPENTHREADS_LIBRARY
      OPENTHREADS_FOUND, if false, do not try to link to OpenThreads
      OPENTHREADS_INCLUDE_DIR, where to find the headers
 
      $OPENTHREADS_DIR is an environment variable that would correspond to
      the ./configure --prefix=$OPENTHREADS_DIR used in building osg.
 
      [CMake 2.8.10]: The CMake variables OPENTHREADS_DIR or OSG_DIR can now
      be used as well to influence detection, instead of needing to specify
      an environment variable.

        PNG_LIBRARIES, the libraries to link against to use PNG.
        PNG_DEFINITIONS - You should add_definitons(${PNG_DEFINITIONS}) before compiling code that includes png library files.
        PNG_FOUND, If false, do not try to use PNG.
        PNG_VERSION_STRING - the version of the PNG library found (since CMake 2.8.8)
 
      Also defined, but not for general use are
 
        PNG_LIBRARY, where to find the PNG library.
 
      For backward compatiblity the variable PNG_INCLUDE_DIR is also set.
      It has the same value as PNG_INCLUDE_DIRS.
 
      Since PNG depends on the ZLib compression library, none of the above
      will be defined unless ZLib can be found.
 
  FindPackageHandleStandardArgs
       
 
      FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> ...  )
 
      This function is intended to be used in FindXXX.cmake modules files.
      It handles the REQUIRED, QUIET and version-related arguments to
      find_package().  It also sets the <UPPERCASED_NAME>_FOUND variable.
      The package is considered found if all variables <var1>...  listed
      contain valid results, e.g.  valid filepaths.
 
      There are two modes of this function.  The first argument in both
      modes is the name of the Find-module where it is called (in original
      casing).
 
      The first simple mode looks like this:
 
          FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> (DEFAULT_MSG|"Custom failure message") <var1>...<varN> )
 
      If the variables <var1> to <varN> are all valid, then
      <UPPERCASED_NAME>_FOUND will be set to TRUE.  If DEFAULT_MSG is given
      as second argument, then the function will generate itself useful
      success and error messages.  You can also supply a custom error
      message for the failure case.  This is not recommended.
 
      The second mode is more powerful and also supports version checking:
 
          FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME [REQUIRED_VARS <var1>...<varN>]
                                                  [VERSION_VAR  <versionvar>]
                                                  [HANDLE_COMPONENTS]
                                                  [CONFIG_MODE]
                                                  [FAIL_MESSAGE "Custom failure message"] )
 
     
 
      As above, if <var1> through <varN> are all valid,
      <UPPERCASED_NAME>_FOUND will be set to TRUE.  After REQUIRED_VARS the
      variables which are required for this package are listed.  Following
      VERSION_VAR the name of the variable can be specified which holds the
      version of the package which has been found.  If this is done, this
      version will be checked against the (potentially) specified required
      version used in the find_package() call.  The EXACT keyword is also
      handled.  The default messages include information about the required
      version and the version which has been actually found, both if the
      version is ok or not.  If the package supports components, use the
      HANDLE_COMPONENTS option to enable handling them.  In this case,
      find_package_handle_standard_args() will report which components have
      been found and which are missing, and the <NAME>_FOUND variable will
      be set to FALSE if any of the required components (i.e.  not the ones
      listed after OPTIONAL_COMPONENTS) are missing.  Use the option
      CONFIG_MODE if your FindXXX.cmake module is a wrapper for a
      find_package(...  NO_MODULE) call.  In this case VERSION_VAR will be
      set to <NAME>_VERSION and the macro will automatically check whether
      the Config module was found.  Via FAIL_MESSAGE a custom failure
      message can be specified, if this is not used, the default message
      will be displayed.
 
      Example for mode 1:
 
          FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2  DEFAULT_MSG  LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)
 
     
 
      LibXml2 is considered to be found, if both LIBXML2_LIBRARY and
      LIBXML2_INCLUDE_DIR are valid.  Then also LIBXML2_FOUND is set to
      TRUE.  If it is not found and REQUIRED was used, it fails with
      FATAL_ERROR, independent whether QUIET was used or not.  If it is
      found, success will be reported, including the content of <var1>.  On
      repeated Cmake runs, the same message won't be printed again.
 
      Example for mode 2:
 
          FIND_PACKAGE_HANDLE_STANDARD_ARGS(BISON  REQUIRED_VARS BISON_EXECUTABLE
                                                    VERSION_VAR BISON_VERSION)
 
      In this case, BISON is considered to be found if the variable(s)
      listed after REQUIRED_VAR are all valid, i.e.  BISON_EXECUTABLE in
      this case.  Also the version of BISON will be checked by using the
      version contained in BISON_VERSION.  Since no FAIL_MESSAGE is given,
      the default messages will be printed.
 
      Another example for mode 2:
 
          find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
          FIND_PACKAGE_HANDLE_STANDARD_ARGS(Automoc4  CONFIG_MODE)
 
      In this case, FindAutmoc4.cmake wraps a call to find_package(Automoc4
      NO_MODULE) and adds an additional search directory for automoc4.  The
      following FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper
      success/error message.
 
  FindPackageMessage
       
 
      FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")
 
      This macro is intended to be used in FindXXX.cmake modules files.  It
      will print a message once for each unique find result.  This is useful
      for telling the user where a package was found.  The first argument
      specifies the name (XXX) of the package.  The second argument
      specifies the message to display.  The third argument lists details
      about the find result so that if they change the message will be
      displayed again.  The macro also obeys the QUIET argument to the
      find_package command.
 
      Example:
 
        if(X11_FOUND)
          FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
            "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
        else()
          ...
        endif()
 
 
  FindPerl
      Find perl
 
      this module looks for Perl
 
        PERL_EXECUTABLE    - the full path to perl
        PERL_FOUND          - If false, don't attempt to use perl.
        PERL_VERSION_STRING - version of perl found (since CMake 2.8.8)
 
 
  FindPerlLibs
      Find Perl libraries
 
      This module finds if PERL is installed and determines where the
      include files and libraries are.  It also determines what the name of
      the library is.  This code sets the following variables:
 
        PERLLIBS_FOUND    = True if perl.h & libperl were found
        PERL_INCLUDE_PATH = path to where perl.h is found
        PERL_LIBRARY      = path to libperl
        PERL_EXECUTABLE  = full path to the perl binary
 
     
 
      The minimum required version of Perl can be specified using the
      standard syntax, e.g.  find_package(PerlLibs 6.0)
 
        The following variables are also available if needed
        (introduced after CMake 2.6.4)
 
     
 
        PERL_SITESEARCH    = path to the sitesearch install dir
        PERL_SITELIB      = path to the sitelib install directory
        PERL_VENDORARCH    = path to the vendor arch install directory
        PERL_VENDORLIB    = path to the vendor lib install directory
        PERL_ARCHLIB      = path to the arch lib install directory
        PERL_PRIVLIB      = path to the priv lib install directory
        PERL_EXTRA_C_FLAGS = Compilation flags used to build perl
 
     
 
 
  FindPhysFS
       
 
      Locate PhysFS library This module defines PHYSFS_LIBRARY, the name of
      the library to link against PHYSFS_FOUND, if false, do not try to link
      to PHYSFS PHYSFS_INCLUDE_DIR, where to find physfs.h
 
      $PHYSFSDIR is an environment variable that would correspond to the
      ./configure --prefix=$PHYSFSDIR used in building PHYSFS.
 
      Created by Eric Wing.
 
  FindPike
      Find Pike
 
      This module finds if PIKE is installed and determines where the
      include files and libraries are.  It also determines what the name of
      the library is.  This code sets the following variables:
 
        PIKE_INCLUDE_PATH      = path to where program.h is found
        PIKE_EXECUTABLE        = full path to the pike binary
 
     
 
 
  FindPkgConfig
      a pkg-config module for CMake
 
     
 
      Usage:
 
          pkg_check_modules(<PREFIX> [REQUIRED] [QUIET] <MODULE> [<MODULE>]*)
            checks for all the given modules
 
     
 
          pkg_search_module(<PREFIX> [REQUIRED] [QUIET] <MODULE> [<MODULE>]*)
            checks for given modules and uses the first working one
 
     
 
      When the 'REQUIRED' argument was set, macros will fail with an error
      when module(s) could not be found
 
      When the 'QUIET' argument is set, no status messages will be printed.
 
      It sets the following variables:
 
          PKG_CONFIG_FOUND          ... if pkg-config executable was found
          PKG_CONFIG_EXECUTABLE    ... pathname of the pkg-config program
          PKG_CONFIG_VERSION_STRING ... the version of the pkg-config program found
                                        (since CMake 2.8.8)
 
     
 
      For the following variables two sets of values exist; first one is the
      common one and has the given PREFIX.  The second set contains flags
      which are given out when pkgconfig was called with the '--static'
      option.
 
          <XPREFIX>_FOUND          ... set to 1 if module(s) exist
          <XPREFIX>_LIBRARIES      ... only the libraries (w/o the '-l')
          <XPREFIX>_LIBRARY_DIRS  ... the paths of the libraries (w/o the '-L')
          <XPREFIX>_LDFLAGS        ... all required linker flags
          <XPREFIX>_LDFLAGS_OTHER  ... all other linker flags
          <XPREFIX>_INCLUDE_DIRS  ... the '-I' preprocessor flags (w/o the '-I')
          <XPREFIX>_CFLAGS        ... all required cflags
          <XPREFIX>_CFLAGS_OTHER  ... the other compiler flags
 
     
 
          <XPREFIX> = <PREFIX>        for common case
          <XPREFIX> = <PREFIX>_STATIC for static linking
 
     
 
      There are some special variables whose prefix depends on the count of
      given modules.  When there is only one module, <PREFIX> stays
      unchanged.  When there are multiple modules, the prefix will be
      changed to <PREFIX>_<MODNAME>:
 
          <XPREFIX>_VERSION    ... version of the module
          <XPREFIX>_PREFIX    ... prefix-directory of the module
          <XPREFIX>_INCLUDEDIR ... include-dir of the module
          <XPREFIX>_LIBDIR    ... lib-dir of the module
 
     
 
          <XPREFIX> = <PREFIX>  when |MODULES| == 1, else
          <XPREFIX> = <PREFIX>_<MODNAME>
 
     
 
      A <MODULE> parameter can have the following formats:
 
          {MODNAME}            ... matches any version
          {MODNAME}>={VERSION} ... at least version <VERSION> is required
          {MODNAME}={VERSION}  ... exactly version <VERSION> is required
          {MODNAME}<={VERSION} ... modules must not be newer than <VERSION>
 
     
 
      Examples
 
          pkg_check_modules (GLIB2  glib-2.0)
 
     
 
          pkg_check_modules (GLIB2  glib-2.0>=2.10)
            requires at least version 2.10 of glib2 and defines e.g.
              GLIB2_VERSION=2.10.3
 
     
 
          pkg_check_modules (FOO    glib-2.0>=2.10 gtk+-2.0)
            requires both glib2 and gtk2, and defines e.g.
              FOO_glib-2.0_VERSION=2.10.3
              FOO_gtk+-2.0_VERSION=2.8.20
 
     
 
          pkg_check_modules (XRENDER REQUIRED xrender)

  FindPostgreSQL
      Find the PostgreSQL installation.
 
      In Windows, we make the assumption that, if the PostgreSQL files are
      installed, the default directory will be C:\Program Files\PostgreSQL.
 
      This module defines
 
        PostgreSQL_LIBRARIES - the PostgreSQL libraries needed for linking
        PostgreSQL_INCLUDE_DIRS - the directories of the PostgreSQL headers
        PostgreSQL_VERSION_STRING - the version of PostgreSQL found (since CMake 2.8.8)
 
 
  FindProducer
       
 
      Though Producer isn't directly part of OpenSceneGraph, its primary
      user is OSG so I consider this part of the Findosg* suite used to find
      OpenSceneGraph components.  You'll notice that I accept OSGDIR as an
      environment path.
 
      Each component is separate and you must opt in to each module.  You
      must also opt into OpenGL (and OpenThreads?) as these modules won't do
      it for you.  This is to allow you control over your own system piece
      by piece in case you need to opt out of certain components or change
      the Find behavior for a particular module (perhaps because the default
      FindOpenGL.cmake module doesn't work with your system as an example).
      If you want to use a more convenient module that includes everything,
      use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake
      modules.
 
      Locate Producer This module defines PRODUCER_LIBRARY PRODUCER_FOUND,
      if false, do not try to link to Producer PRODUCER_INCLUDE_DIR, where
      to find the headers
 
      $PRODUCER_DIR is an environment variable that would correspond to the
      ./configure --prefix=$PRODUCER_DIR used in building osg.

                                    (vsprojects/Debug & vsprojects/Release) will be searched
                                    for libraries and binaries.
 
     
 
          PROTOBUF_IMPORT_DIRS    - List of additional directories to be searched for
                                    imported .proto files. (New in CMake 2.8.8)
 
     
 
      Defines the following variables:

  FindPythonInterp
      Find python interpreter
 
      This module finds if Python interpreter is installed and determines
      where the executables are.  This code sets the following variables:
 
        PYTHONINTERP_FOUND        - Was the Python executable found
        PYTHON_EXECUTABLE          - path to the Python interpreter
 
     
 
        PYTHON_VERSION_STRING      - Python version found e.g. 2.5.2
        PYTHON_VERSION_MAJOR      - Python major version found e.g. 2
        PYTHON_VERSION_MINOR      - Python minor version found e.g. 5
        PYTHON_VERSION_PATCH      - Python patch version found e.g. 2
 
     
 
      The Python_ADDITIONAL_VERSIONS variable can be used to specify a list
      of version numbers that should be taken into account when searching
      for Python.  You need to set this variable before calling
      find_package(PythonInterp).
 
  FindPythonLibs
      Find python libraries
 
      This module finds if Python is installed and determines where the
      include files and libraries are.  It also determines what the name of
      the library is.  This code sets the following variables:
 
        PYTHONLIBS_FOUND          - have the Python libs been found
        PYTHON_LIBRARIES          - path to the python library
        PYTHON_INCLUDE_PATH        - path to where Python.h is found (deprecated)
        PYTHON_INCLUDE_DIRS        - path to where Python.h is found
        PYTHON_DEBUG_LIBRARIES    - path to the debug library (deprecated)
        PYTHONLIBS_VERSION_STRING  - version of the Python libs found (since CMake 2.8.8)
 
     
 
      The Python_ADDITIONAL_VERSIONS variable can be used to specify a list
      of version numbers that should be taken into account when searching
      for Python.  You need to set this variable before calling
      find_package(PythonLibs).
 
      If you'd like to specify the installation of Python to use, you should
      modify the following cache variables:
 
        PYTHON_LIBRARY            - path to the python library
        PYTHON_INCLUDE_DIR        - path to where Python.h is found
 
 
  FindQt
      Searches for all installed versions of Qt.
 
      This should only be used if your project can work with multiple
      versions of Qt.  If not, you should just directly use FindQt4 or
      FindQt3.  If multiple versions of Qt are found on the machine, then
      The user must set the option DESIRED_QT_VERSION to the version they
      want to use.  If only one version of qt is found on the machine, then
      the DESIRED_QT_VERSION is set to that version and the matching FindQt3
      or FindQt4 module is included.  Once the user sets DESIRED_QT_VERSION,
      then the FindQt3 or FindQt4 module is included.
 
        QT_REQUIRED if this is set to TRUE then if CMake can
                    not find Qt4 or Qt3 an error is raised
                    and a message is sent to the user.
 
     
 
        DESIRED_QT_VERSION OPTION is created
        QT4_INSTALLED is set to TRUE if qt4 is found.
        QT3_INSTALLED is set to TRUE if qt3 is found.
 
 
  FindQt3
      Locate Qt include paths and libraries
 
      This module defines:
 
        QT_INCLUDE_DIR    - where to find qt.h, etc.
        QT_LIBRARIES      - the libraries to link against to use Qt.
        QT_DEFINITIONS    - definitions to use when
                            compiling code that uses Qt.
        QT_FOUND          - If false, don't try to use Qt.
        QT_VERSION_STRING - the version of Qt found
 
     
 
      If you need the multithreaded version of Qt, set QT_MT_REQUIRED to
      TRUE
 
      Also defined, but not for general use are:
 
        QT_MOC_EXECUTABLE, where to find the moc tool.
        QT_UIC_EXECUTABLE, where to find the uic tool.
        QT_QT_LIBRARY, where to find the Qt library.
        QT_QTMAIN_LIBRARY, where to find the qtmain
          library. This is only required by Qt3 on Windows.
 
 
  FindQt4
      Find Qt 4
 
      This module can be used to find Qt4.  The most important issue is that
      the Qt4 qmake is available via the system path.  This qmake is then
      used to detect basically everything else.  This module defines a
      number of key variables and macros.  The variable QT_USE_FILE is set
      which is the path to a CMake file that can be included to compile Qt 4
      applications and libraries.  It sets up the compilation environment
      for include directories, preprocessor defines and populates a
      QT_LIBRARIES variable.
 
      Typical usage could be something like:
 
          find_package(Qt4 4.4.3 REQUIRED QtCore QtGui QtXml)
          include(${QT_USE_FILE})
          add_executable(myexe main.cpp)
          target_link_libraries(myexe ${QT_LIBRARIES})
 
     
 
      The minimum required version can be specified using the standard
      find_package()-syntax (see example above).  For compatibility with
      older versions of FindQt4.cmake it is also possible to set the
      variable QT_MIN_VERSION to the minimum required version of Qt4 before
      the find_package(Qt4) command.  If both are used, the version used in
      the find_package() command overrides the one from QT_MIN_VERSION.
 
      When using the components argument, QT_USE_QT* variables are
      automatically set for the QT_USE_FILE to pick up.  If one wishes to
      manually set them, the available ones to set include:
 
                          QT_DONT_USE_QTCORE
                          QT_DONT_USE_QTGUI
                          QT_USE_QT3SUPPORT
                          QT_USE_QTASSISTANT
                          QT_USE_QAXCONTAINER
                          QT_USE_QAXSERVER
                          QT_USE_QTDESIGNER
                          QT_USE_QTMOTIF
                          QT_USE_QTMAIN
                          QT_USE_QTMULTIMEDIA
                          QT_USE_QTNETWORK
                          QT_USE_QTNSPLUGIN
                          QT_USE_QTOPENGL
                          QT_USE_QTSQL
                          QT_USE_QTXML
                          QT_USE_QTSVG
                          QT_USE_QTTEST
                          QT_USE_QTUITOOLS
                          QT_USE_QTDBUS
                          QT_USE_QTSCRIPT
                          QT_USE_QTASSISTANTCLIENT
                          QT_USE_QTHELP
                          QT_USE_QTWEBKIT
                          QT_USE_QTXMLPATTERNS
                          QT_USE_PHONON
                          QT_USE_QTSCRIPTTOOLS
                          QT_USE_QTDECLARATIVE
 
     
 
        QT_USE_IMPORTED_TARGETS
              If this variable is set to TRUE, FindQt4.cmake will create imported
              library targets for the various Qt libraries and set the
              library variables like QT_QTCORE_LIBRARY to point at these imported
              targets instead of the library file on disk. This provides much better
              handling of the release and debug versions of the Qt libraries and is
              also always backwards compatible, except for the case that dependencies
              of libraries are exported, these will then also list the names of the
              imported targets as dependency and not the file location on disk. This
              is much more flexible, but requires that FindQt4.cmake is executed before
              such an exported dependency file is processed.
 
     
 
      There are also some files that need processing by some Qt tools such
      as moc and uic.  Listed below are macros that may be used to process
      those files.
 
        macro QT4_WRAP_CPP(outfiles inputfile ... OPTIONS ...)
              create moc code from a list of files containing Qt class with
              the Q_OBJECT declaration.  Per-directory preprocessor definitions
              are also added.  Options may be given to moc, such as those found
              when executing "moc -help".
 
     
 
        macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
              create code from a list of Qt designer ui files.
              Options may be given to uic, such as those found
              when executing "uic -help"
 
     
 
        macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
              create code from a list of Qt resource files.
              Options may be given to rcc, such as those found
              when executing "rcc -help"
 
     
 
        macro QT4_GENERATE_MOC(inputfile outputfile )
              creates a rule to run moc on infile and create outfile.
              Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
              because you need a custom filename for the moc file or something similar.
 
     
 
        macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... )
              This macro is still experimental.
              It can be used to have moc automatically handled.
              So if you have the files foo.h and foo.cpp, and in foo.h a
              a class uses the Q_OBJECT macro, moc has to run on it. If you don't
              want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
              #include "foo.moc"
              in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will the
              scan all listed files at cmake-time for such included moc files and if it finds
              them cause a rule to be generated to run moc at build time on the
              accompanying header file foo.h.
              If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro.
 
     
 
              You should have a look on the AUTOMOC property for targets to achieve the same results.
 
     
 
        macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
              Create a the interface header and implementation files with the
              given basename from the given interface xml file and add it to
              the list of sources.
 
     
 
              You can pass additional parameters to the qdbusxml2cpp call by setting
              properties on the input file:
 
     
 
              INCLUDE the given file will be included in the generate interface header
 
     
 
              CLASSNAME the generated class is named accordingly
 
     
 
              NO_NAMESPACE the generated class is not wrapped in a namespace
 
     
 
        macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
              Create the interface header and implementation files
              for all listed interface xml files.
              The basename will be automatically determined from the name of the xml file.
 
     
 
              The source file properties described for QT4_ADD_DBUS_INTERFACE also apply here.
 
     
 
        macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname [basename] [classname])
              create a dbus adaptor (header and implementation file) from the xml file
              describing the interface, and add it to the list of sources. The adaptor
              forwards the calls to a parent class, defined in parentheader and named
              parentclassname. The name of the generated files will be
              <basename>adaptor.{cpp,h} where basename defaults to the basename of the xml file.
              If <classname> is provided, then it will be used as the classname of the
              adaptor itself.
 
     
 
        macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] OPTIONS ...)
              generate the xml interface file from the given header.
              If the optional argument interfacename is omitted, the name of the
              interface file is constructed from the basename of the header with
              the suffix .xml appended.
              Options may be given to qdbuscpp2xml, such as those found when executing "qdbuscpp2xml --help"
 
     
 
        macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ...
                                      ts_files ... OPTIONS ...)
              out: qm_files
              in:  directories sources ts_files
              options: flags to pass to lupdate, such as -extensions to specify
              extensions for a directory scan.
              generates commands to create .ts (vie lupdate) and .qm
              (via lrelease) - files from directories and/or sources. The ts files are
              created and/or updated in the source tree (unless given with full paths).
              The qm files are generated in the build tree.
              Updating the translations can be done by adding the qm_files
              to the source list of your library/executable, so they are
              always updated, or by adding a custom target to control when
              they get updated/generated.
 
     
 
        macro QT4_ADD_TRANSLATION( qm_files ts_files ... )
              out: qm_files
              in:  ts_files
              generates commands to create .qm from .ts - files. The generated
              filenames can be found in qm_files. The ts_files
              must exists and are not updated in any way.
 
     
 
      function QT4_USE_MODULES( target [link_type] modules...)
 
              Make <target> use the <modules> from Qt. Using a Qt module means
              to link to the library, add the relevant include directories for the module,
              and add the relevant compiler defines for using the module.
              Modules are roughly equivalent to components of Qt4, so usage would be
              something like:
                qt4_use_modules(myexe Core Gui Declarative)
              to use QtCore, QtGui and QtDeclarative. The optional <link_type> argument can
              be specified as either LINK_PUBLIC or LINK_PRIVATE to specify the same argument
              to the target_link_libraries call.
 
     
 
     
 
        Below is a detailed list of variables that FindQt4.cmake sets.

  FindQuickTime
       
 
      Locate QuickTime This module defines QUICKTIME_LIBRARY
      QUICKTIME_FOUND, if false, do not try to link to gdal
      QUICKTIME_INCLUDE_DIR, where to find the headers
 
      $QUICKTIME_DIR is an environment variable that would correspond to the
      ./configure --prefix=$QUICKTIME_DIR
 
      Created by Eric Wing.
 
  FindRTI
      Try to find M&S HLA RTI libraries
 
      This module finds if any HLA RTI is installed and locates the standard
      RTI include files and libraries.
 
      RTI is a simulation infrastructure standardized by IEEE and SISO.  It
      has a well defined C++ API that assures that simulation applications
      are independent on a particular RTI implementation.
 
        http://en.wikipedia.org/wiki/Run-Time_Infrastructure_(simulation)
 
     
 
      This code sets the following variables:
 
        RTI_INCLUDE_DIR = the directory where RTI includes file are found
        RTI_LIBRARIES = The libraries to link against to use RTI
        RTI_DEFINITIONS = -DRTI_USES_STD_FSTREAM
        RTI_FOUND = Set to FALSE if any HLA RTI was not found
 
     
 
      Report problems to <certi-devel@nongnu.org>
 
  FindRuby
      Find Ruby
 
      This module finds if Ruby is installed and determines where the
      include files and libraries are.  Ruby 1.8 and 1.9 are supported.
 
      The minimum required version of Ruby can be specified using the
      standard syntax, e.g.  find_package(Ruby 1.8)
 
      It also determines what the name of the library is.  This code sets
      the following variables:
 
        RUBY_EXECUTABLE  = full path to the ruby binary
        RUBY_INCLUDE_DIRS = include dirs to be used when using the ruby library
        RUBY_LIBRARY      = full path to the ruby library
        RUBY_VERSION      = the version of ruby which was found, e.g. "1.8.7"
        RUBY_FOUND        = set to true if ruby ws found successfully
 
     
 
        RUBY_INCLUDE_PATH = same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, don't use it
 
 
  FindSDL
      Locate SDL library
 
      This module defines
 
        SDL_LIBRARY, the name of the library to link against
        SDL_FOUND, if false, do not try to link to SDL
        SDL_INCLUDE_DIR, where to find SDL.h
        SDL_VERSION_STRING, human-readable string containing the version of SDL
 
     
 
      This module responds to the the flag:
 
        SDL_BUILDING_LIBRARY
          If this is defined, then no SDL_main will be linked in because
          only applications need main().
          Otherwise, it is assumed you are building an application and this
          module will attempt to locate and set the the proper link flags
          as part of the returned SDL_LIBRARY variable.
 
     
 
      Don't forget to include SDLmain.h and SDLmain.m your project for the
      OS X framework based version.  (Other versions link to -lSDLmain which
      this module will try to find on your behalf.) Also for OS X, this
      module will automatically add the -framework Cocoa on your behalf.
 
     
 
      Additional Note: If you see an empty SDL_LIBRARY_TEMP in your
      configuration and no SDL_LIBRARY, it means CMake did not find your SDL
      library (SDL.dll, libsdl.so, SDL.framework, etc).  Set
      SDL_LIBRARY_TEMP to point to your SDL library, and configure again.
      Similarly, if you see an empty SDLMAIN_LIBRARY, you should set this
      value as appropriate.  These values are used to generate the final
      SDL_LIBRARY variable, but when these values are unset, SDL_LIBRARY
      does not get created.
 
     
 
      $SDLDIR is an environment variable that would correspond to the
      ./configure --prefix=$SDLDIR used in building SDL.  l.e.galup 9-20-02
 
      Modified by Eric Wing.  Added code to assist with automated building
      by using environmental variables and providing a more
      controlled/consistent search behavior.  Added new modifications to
      recognize OS X frameworks and additional Unix paths (FreeBSD, etc).
      Also corrected the header search path to follow "proper" SDL
      guidelines.  Added a search for SDLmain which is needed by some
      platforms.  Added a search for threads which is needed by some
      platforms.  Added needed compile switches for MinGW.
 
      On OSX, this will prefer the Framework version (if found) over others.
      People will have to manually change the cache values of SDL_LIBRARY to
      override this selection or set the CMake environment
      CMAKE_INCLUDE_PATH to modify the search paths.
 
      Note that the header path has changed from SDL/SDL.h to just SDL.h
      This needed to change because "proper" SDL convention is #include
      "SDL.h", not <SDL/SDL.h>.  This is done for portability reasons
      because not all systems place things in SDL/ (see FreeBSD).

  FindSDL_sound
      Locates the SDL_sound library
 
     
 
      This module depends on SDL being found and must be called AFTER
      FindSDL.cmake is called.
 
      This module defines
 
        SDL_SOUND_INCLUDE_DIR, where to find SDL_sound.h
        SDL_SOUND_FOUND, if false, do not try to link to SDL_sound
        SDL_SOUND_LIBRARIES, this contains the list of libraries that you need
          to link against. This is a read-only variable and is marked INTERNAL.
        SDL_SOUND_EXTRAS, this is an optional variable for you to add your own
          flags to SDL_SOUND_LIBRARIES. This is prepended to SDL_SOUND_LIBRARIES.
          This is available mostly for cases this module failed to anticipate for
          and you must add additional flags. This is marked as ADVANCED.
        SDL_SOUND_VERSION_STRING, human-readable string containing the version of SDL_sound
 
     
 
      This module also defines (but you shouldn't need to use directly)
 
          SDL_SOUND_LIBRARY, the name of just the SDL_sound library you would link
          against. Use SDL_SOUND_LIBRARIES for you link instructions and not this one.
 
      And might define the following as needed
 
          MIKMOD_LIBRARY
          MODPLUG_LIBRARY
          OGG_LIBRARY
          VORBIS_LIBRARY
          SMPEG_LIBRARY
          FLAC_LIBRARY
          SPEEX_LIBRARY
 
     
 
      Typically, you should not use these variables directly, and you should
      use SDL_SOUND_LIBRARIES which contains SDL_SOUND_LIBRARY and the other
      audio libraries (if needed) to successfully compile on your system.
 
      Created by Eric Wing.  This module is a bit more complicated than the
      other FindSDL* family modules.  The reason is that SDL_sound can be
      compiled in a large variety of different ways which are independent of
      platform.  SDL_sound may dynamically link against other 3rd party
      libraries to get additional codec support, such as Ogg Vorbis, SMPEG,
      ModPlug, MikMod, FLAC, Speex, and potentially others.  Under some
      circumstances which I don't fully understand, there seems to be a
      requirement that dependent libraries of libraries you use must also be
      explicitly linked against in order to successfully compile.  SDL_sound
      does not currently have any system in place to know how it was
      compiled.  So this CMake module does the hard work in trying to
      discover which 3rd party libraries are required for building (if any).
      This module uses a brute force approach to create a test program that
      uses SDL_sound, and then tries to build it.  If the build fails, it
      parses the error output for known symbol names to figure out which
      libraries are needed.
 
      Responds to the $SDLDIR and $SDLSOUNDDIR environmental variable that
      would correspond to the ./configure --prefix=$SDLDIR used in building
      SDL.
 
      On OSX, this will prefer the Framework version (if found) over others.
      People will have to manually change the cache values of SDL_LIBRARY to
      override this selectionor set the CMake environment CMAKE_INCLUDE_PATH
      to modify the search paths.
 
  FindSDL_ttf
      Locate SDL_ttf library
 
      This module defines:
 
        SDL_TTF_LIBRARIES, the name of the library to link against
        SDL_TTF_INCLUDE_DIRS, where to find the headers
        SDL_TTF_FOUND, if false, do not try to link against
        SDL_TTF_VERSION_STRING - human-readable string containing the version of SDL_ttf
 
     
 
      For backward compatiblity the following variables are also set:
 
        SDLTTF_LIBRARY (same value as SDL_TTF_LIBRARIES)
        SDLTTF_INCLUDE_DIR (same value as SDL_TTF_INCLUDE_DIRS)
        SDLTTF_FOUND (same value as SDL_TTF_FOUND)
 
     
 
      $SDLDIR is an environment variable that would correspond to the
      ./configure --prefix=$SDLDIR used in building SDL.
 
      Created by Eric Wing.  This was influenced by the FindSDL.cmake
      module, but with modifications to recognize OS X frameworks and
      additional Unix paths (FreeBSD, etc).
 
  FindSWIG
      Find SWIG
 
      This module finds an installed SWIG.  It sets the following variables:
 
        SWIG_FOUND - set to true if SWIG is found
        SWIG_DIR - the directory where swig is installed
        SWIG_EXECUTABLE - the path to the swig executable
        SWIG_VERSION  - the version number of the swig executable
 
     
 
      The minimum required version of SWIG can be specified using the
      standard syntax, e.g.  find_package(SWIG 1.1)
 
      All information is collected from the SWIG_EXECUTABLE so the version
      to be found can be changed from the command line by means of setting
      SWIG_EXECUTABLE
 
 
  FindSelfPackers
      Find upx
 
      This module looks for some executable packers (i.e.  software that
      compress executables or shared libs into on-the-fly self-extracting
      executables or shared libs.  Examples:
 
        UPX: http://wildsau.idv.uni-linz.ac.at/mfx/upx.html
 
 
  FindSquish
      -- Typical Use
 
     
 
      This module can be used to find Squish (currently support is aimed at
      version 3).
 
        SQUISH_FOUND                    If false, don't try to use Squish
 
     
 
        SQUISH_INSTALL_DIR              The Squish installation directory (containing bin, lib, etc)
        SQUISH_SERVER_EXECUTABLE        The squishserver executable
        SQUISH_CLIENT_EXECUTABLE        The squishrunner executable
 
     
 
        SQUISH_INSTALL_DIR_FOUND        Was the install directory found?
        SQUISH_SERVER_EXECUTABLE_FOUND  Was the server executable found?
        SQUISH_CLIENT_EXECUTABLE_FOUND  Was the client executable found?
 
     
 
      macro SQUISH_ADD_TEST(testName applicationUnderTest testSuite
      testCase)
 
        enable_testing()
        find_package(Squish)
        if (SQUISH_FOUND)
          SQUISH_ADD_TEST(myTestName myApplication testSuiteName testCaseName)
        endif ()
 
     
 
 
  FindSubversion
      Extract information from a subversion working copy
 
      The module defines the following variables:
 
        Subversion_SVN_EXECUTABLE - path to svn command line client
        Subversion_VERSION_SVN - version of svn command line client
        Subversion_FOUND - true if the command line client was found
        SUBVERSION_FOUND - same as Subversion_FOUND, set for compatiblity reasons
 
     
 
      The minimum required version of Subversion can be specified using the
      standard syntax, e.g.  find_package(Subversion 1.4)
 
      If the command line client executable is found two macros are defined:
 
        Subversion_WC_INFO(<dir> <var-prefix>)
        Subversion_WC_LOG(<dir> <var-prefix>)
 
      Subversion_WC_INFO extracts information of a subversion working copy
      at a given location.  This macro defines the following variables:
 
        <var-prefix>_WC_URL - url of the repository (at <dir>)
        <var-prefix>_WC_ROOT - root url of the repository
        <var-prefix>_WC_REVISION - current revision
        <var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit
        <var-prefix>_WC_LAST_CHANGED_DATE - date of last commit
        <var-prefix>_WC_LAST_CHANGED_REV - revision of last commit
        <var-prefix>_WC_INFO - output of command `svn info <dir>'
 
      Subversion_WC_LOG retrieves the log message of the base revision of a
      subversion working copy at a given location.  This macro defines the
      variable:
 
        <var-prefix>_LAST_CHANGED_LOG - last log of base revision
 
      Example usage:
 
        find_package(Subversion)
        if(SUBVERSION_FOUND)
          Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
          message("Current revision is ${Project_WC_REVISION}")
          Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project)
          message("Last changed log is ${Project_LAST_CHANGED_LOG}")
        endif()
 
 
  FindTCL
      TK_INTERNAL_PATH was removed.
 
      This module finds if Tcl is installed and determines where the include
      files and libraries are.  It also determines what the name of the
      library is.  This code sets the following variables:
 
        TCL_FOUND              = Tcl was found
        TK_FOUND              = Tk was found
        TCLTK_FOUND            = Tcl and Tk were found
        TCL_LIBRARY            = path to Tcl library (tcl tcl80)
        TCL_INCLUDE_PATH      = path to where tcl.h can be found
        TCL_TCLSH              = path to tclsh binary (tcl tcl80)
        TK_LIBRARY            = path to Tk library (tk tk80 etc)
        TK_INCLUDE_PATH        = path to where tk.h can be found
        TK_WISH                = full path to the wish executable
 
     
 
      In an effort to remove some clutter and clear up some issues for
      people who are not necessarily Tcl/Tk gurus/developpers, some
      variables were moved or removed.  Changes compared to CMake 2.4 are:
 
          => they were only useful for people writing Tcl/Tk extensions.
          => these libs are not packaged by default with Tcl/Tk distributions.
            Even when Tcl/Tk is built from source, several flavors of debug libs
            are created and there is no real reason to pick a single one
            specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx).
            Let's leave that choice to the user by allowing him to assign
            TCL_LIBRARY to any Tcl library, debug or not.
          => this ended up being only a Win32 variable, and there is a lot of
            confusion regarding the location of this file in an installed Tcl/Tk
            tree anyway (see 8.5 for example). If you need the internal path at
            this point it is safer you ask directly where the *source* tree is
            and dig from there.
 
 
  FindTIFF
      Find TIFF library
 
      Find the native TIFF includes and library This module defines
 
        TIFF_INCLUDE_DIR, where to find tiff.h, etc.
        TIFF_LIBRARIES, libraries to link against to use TIFF.
        TIFF_FOUND, If false, do not try to use TIFF.
 
      also defined, but not for general use are
 
        TIFF_LIBRARY, where to find the TIFF library.
 
 
  FindTclStub
      TCL_STUB_LIBRARY_DEBUG and TK_STUB_LIBRARY_DEBUG were removed.
 
      This module finds Tcl stub libraries.  It first finds Tcl include
      files and libraries by calling FindTCL.cmake.  How to Use the Tcl
      Stubs Library:
 
          http://tcl.activestate.com/doc/howto/stubs.html
 
      Using Stub Libraries:
 
          http://safari.oreilly.com/0130385603/ch48lev1sec3
 
      This code sets the following variables:
 
        TCL_STUB_LIBRARY      = path to Tcl stub library
        TK_STUB_LIBRARY        = path to Tk stub library
        TTK_STUB_LIBRARY      = path to ttk stub library
 
     
 
      In an effort to remove some clutter and clear up some issues for
      people who are not necessarily Tcl/Tk gurus/developpers, some
      variables were moved or removed.  Changes compared to CMake 2.4 are:

            TCL_STUB_LIBRARY to any Tcl library, debug or not.
 
 
  FindTclsh
      Find tclsh
 
      This module finds if TCL is installed and determines where the include

      library is.  This code sets the following variables:
 
        TCLSH_FOUND = TRUE if tclsh has been found
        TCL_TCLSH = the path to the tclsh executable
 
      In cygwin, look for the cygwin version first.  Don't look for it later
      to avoid finding the cygwin version on a Win32 build.

                              (meaningless for odd minor).
        VTK_INCLUDE_DIRS  - Include directories for VTK
        VTK_LIBRARY_DIRS  - Link directories for VTK libraries
        VTK_KITS          - List of VTK kits, in CAPS
                            (COMMON,IO,) etc.
        VTK_LANGUAGES    - List of wrapped languages, in CAPS
                            (TCL, PYHTON,) etc.
 
      The following cache entries must be set by the user to locate VTK:
 
        VTK_DIR  - The directory containing VTKConfig.cmake.
                    This is either the root of the build tree,
                    or the lib/vtk directory.  This is the
                    only cache entry.
 
      The following variables are set for backward compatibility and should
      not be used in new code:
 
        USE_VTK_FILE - The full path to the UseVTK.cmake file.

  Findosg
       
 
     
 
      NOTE: It is highly recommended that you use the new
      FindOpenSceneGraph.cmake introduced in CMake 2.6.3 and not use this
      Find module directly.
 
      This is part of the Findosg* suite used to find OpenSceneGraph
      components.  Each component is separate and you must opt in to each
      module.  You must also opt into OpenGL and OpenThreads (and Producer
      if needed) as these modules won't do it for you.  This is to allow you
      control over your own system piece by piece in case you need to opt
      out of certain components or change the Find behavior for a particular
      module (perhaps because the default FindOpenGL.cmake module doesn't
      work with your system as an example).  If you want to use a more
      convenient module that includes everything, use the
      FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.
 
      Locate osg This module defines
 
      OSG_FOUND - Was the Osg found? OSG_INCLUDE_DIR - Where to find the
      headers OSG_LIBRARIES - The libraries to link against for the OSG (use
      this)
 
      OSG_LIBRARY - The OSG library OSG_LIBRARY_DEBUG - The OSG debug
      library
 
      $OSGDIR is an environment variable that would correspond to the
      ./configure --prefix=$OSGDIR used in building osg.

  FindwxWidgets
      Find a wxWidgets (a.k.a., wxWindows) installation.
 
      This module finds if wxWidgets is installed and selects a default
      configuration to use.  wxWidgets is a modular library.  To specify the
      modules that you will use, you need to name them as components to the
      package:
 
      find_package(wxWidgets COMPONENTS core base ...)
 
      There are two search branches: a windows style and a unix style.  For
      windows, the following variables are searched for and set to defaults
      in case of multiple choices.  Change them if the defaults are not
      desired (i.e., these are the only variables you should change to
      select a configuration):
 
        wxWidgets_ROOT_DIR      - Base wxWidgets directory
                                  (e.g., C:/wxWidgets-2.6.3).
        wxWidgets_LIB_DIR      - Path to wxWidgets libraries
                                  (e.g., C:/wxWidgets-2.6.3/lib/vc_lib).
        wxWidgets_CONFIGURATION - Configuration to use
                                  (e.g., msw, mswd, mswu, mswunivud, etc.)
        wxWidgets_EXCLUDE_COMMON_LIBRARIES
                                - Set to TRUE to exclude linking of
                                  commonly required libs (e.g., png tiff
                                  jpeg zlib regex expat).
 
     
 
      For unix style it uses the wx-config utility.  You can select between
      debug/release, unicode/ansi, universal/non-universal, and
      static/shared in the QtDialog or ccmake interfaces by turning ON/OFF
      the following variables:
 
        wxWidgets_USE_DEBUG
        wxWidgets_USE_UNICODE
        wxWidgets_USE_UNIVERSAL
        wxWidgets_USE_STATIC
 
     
 
      There is also a wxWidgets_CONFIG_OPTIONS variable for all other
      options that need to be passed to the wx-config utility.  For example,
      to use the base toolkit found in the /usr/local path, set the variable
      (before calling the FIND_PACKAGE command) as such:
 
        set(wxWidgets_CONFIG_OPTIONS --toolkit=base --prefix=/usr)
 
     
 
      The following are set after the configuration is done for both windows
      and unix style:
 
        wxWidgets_FOUND            - Set to TRUE if wxWidgets was found.
        wxWidgets_INCLUDE_DIRS    - Include directories for WIN32
                                      i.e., where to find "wx/wx.h" and
                                      "wx/setup.h"; possibly empty for unices.
        wxWidgets_LIBRARIES        - Path to the wxWidgets libraries.
        wxWidgets_LIBRARY_DIRS    - compile time link dirs, useful for
                                      rpath on UNIX. Typically an empty string
                                      in WIN32 environment.
        wxWidgets_DEFINITIONS      - Contains defines required to compile/link
                                      against WX, e.g. WXUSINGDLL
        wxWidgets_DEFINITIONS_DEBUG- Contains defines required to compile/link
                                      against WX debug builds, e.g. __WXDEBUG__
        wxWidgets_CXX_FLAGS        - Include dirs and compiler flags for
                                      unices, empty on WIN32. Essentially
                                      "`wx-config --cxxflags`".
        wxWidgets_USE_FILE        - Convenience include file.
 
     
 
      Sample usage:
 
          # Note that for MinGW users the order of libs is important!
          find_package(wxWidgets COMPONENTS net gl core base)
          if(wxWidgets_FOUND)
            include(${wxWidgets_USE_FILE})
            # and for each of your dependent executable/library targets:
            target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})
          endif()
 
     
 
      If wxWidgets is required (i.e., not an optional part):
 
          find_package(wxWidgets REQUIRED net gl core base)
          include(${wxWidgets_USE_FILE})
          # and for each of your dependent executable/library targets:
          target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})
 
 
  FindwxWindows
      Find wxWindows (wxWidgets) installation
 
      This module finds if wxWindows/wxWidgets is installed and determines
      where the include files and libraries are.  It also determines what
      the name of the library is.  Please note this file is DEPRECATED and
      replaced by FindwxWidgets.cmake.  This code sets the following
      variables:
 
        WXWINDOWS_FOUND    = system has WxWindows
        WXWINDOWS_LIBRARIES = path to the wxWindows libraries
                              on Unix/Linux with additional
                              linker flags from
                              "wx-config --libs"
        CMAKE_WXWINDOWS_CXX_FLAGS  = Compiler flags for wxWindows,

  FortranCInterface
      Fortran/C Interface Detection
 
      This module automatically detects the API by which C and Fortran
      languages interact.  Variables indicate if the mangling is found:
 
          FortranCInterface_GLOBAL_FOUND = Global subroutines and functions
          FortranCInterface_MODULE_FOUND = Module subroutines and functions
                                          (declared by "MODULE PROCEDURE")
 
      A function is provided to generate a C header file containing macros
      to mangle symbol names:
 
          FortranCInterface_HEADER(<file>
                                  [MACRO_NAMESPACE <macro-ns>]
                                  [SYMBOL_NAMESPACE <ns>]
                                  [SYMBOLS [<module>:]<function> ...])
 
      It generates in <file> definitions of the following macros:
 
          #define FortranCInterface_GLOBAL (name,NAME) ...
          #define FortranCInterface_GLOBAL_(name,NAME) ...
          #define FortranCInterface_MODULE (mod,name, MOD,NAME) ...
          #define FortranCInterface_MODULE_(mod,name, MOD,NAME) ...
 
      These macros mangle four categories of Fortran symbols, respectively:
 
          - Global symbols without '_': call mysub()
          - Global symbols with '_'  : call my_sub()
          - Module symbols without '_': use mymod; call mysub()
          - Module symbols with '_'  : use mymod; call my_sub()
 
      If mangling for a category is not known, its macro is left undefined.
      All macros require raw names in both lower case and upper case.  The
      MACRO_NAMESPACE option replaces the default "FortranCInterface_"
      prefix with a given namespace "<macro-ns>".
 
      The SYMBOLS option lists symbols to mangle automatically with C
      preprocessor definitions:
 
          <function>          ==> #define <ns><function> ...
          <module>:<function> ==> #define <ns><module>_<function> ...
 
      If the mangling for some symbol is not known then no preprocessor
      definition is created, and a warning is displayed.  The
      SYMBOL_NAMESPACE option prefixes all preprocessor definitions
      generated by the SYMBOLS option with a given namespace "<ns>".
 
      Example usage:
 
          include(FortranCInterface)
          FortranCInterface_HEADER(FC.h MACRO_NAMESPACE "FC_")
 
      This creates a "FC.h" header that defines mangling macros FC_GLOBAL(),
      FC_GLOBAL_(), FC_MODULE(), and FC_MODULE_().
 
      Example usage:
 
          include(FortranCInterface)
          FortranCInterface_HEADER(FCMangle.h
                                  MACRO_NAMESPACE "FC_"
                                  SYMBOL_NAMESPACE "FC_"
                                  SYMBOLS mysub mymod:my_sub)
 
      This creates a "FCMangle.h" header that defines the same FC_*()
      mangling macros as the previous example plus preprocessor symbols
      FC_mysub and FC_mymod_my_sub.
 
      Another function is provided to verify that the Fortran and C/C++
      compilers work together:
 
          FortranCInterface_VERIFY([CXX] [QUIET])
 
      It tests whether a simple test executable using Fortran and C (and C++
      when the CXX option is given) compiles and links successfully.  The
      result is stored in the cache entry FortranCInterface_VERIFIED_C (or
      FortranCInterface_VERIFIED_CXX if CXX is given) as a boolean.  If the
      check fails and QUIET is not given the function terminates with a
      FATAL_ERROR message describing the problem.  The purpose of this check
      is to stop a build early for incompatible compiler combinations.  The
      test is built in the Release configuration.
 
      FortranCInterface is aware of possible GLOBAL and MODULE manglings for
      many Fortran compilers, but it also provides an interface to specify
      new possible manglings.  Set the variables
 
          FortranCInterface_GLOBAL_SYMBOLS
          FortranCInterface_MODULE_SYMBOLS
 
      before including FortranCInterface to specify manglings of the symbols
      "MySub", "My_Sub", "MyModule:MySub", and "My_Module:My_Sub".  For
      example, the code:
 
          set(FortranCInterface_GLOBAL_SYMBOLS mysub_ my_sub__ MYSUB_)
            #                                  ^^^^^  ^^^^^^  ^^^^^
          set(FortranCInterface_MODULE_SYMBOLS
              __mymodule_MOD_mysub __my_module_MOD_my_sub)
            #  ^^^^^^^^    ^^^^^  ^^^^^^^^^    ^^^^^^
          include(FortranCInterface)
 
      tells FortranCInterface to try given GLOBAL and MODULE manglings.
      (The carets point at raw symbol names for clarity in this example but
      are not needed.)
 
  GNUInstallDirs
      Define GNU standard installation directories
 
      Provides install directory variables as defined for GNU software:
 
        http://www.gnu.org/prep/standards/html_node/Directory-Variables.html
 
      Inclusion of this module defines the following variables:
 
        CMAKE_INSTALL_<dir>      - destination for files of a given type
        CMAKE_INSTALL_FULL_<dir> - corresponding absolute path
 
      where <dir> is one of:
 
        BINDIR          - user executables (bin)
        SBINDIR          - system admin executables (sbin)
        LIBEXECDIR      - program executables (libexec)
        SYSCONFDIR      - read-only single-machine data (etc)
        SHAREDSTATEDIR  - modifiable architecture-independent data (com)
        LOCALSTATEDIR    - modifiable single-machine data (var)
        LIBDIR          - object code libraries (lib or lib64 or lib/<multiarch-tuple> on Debian)
        INCLUDEDIR      - C header files (include)
        OLDINCLUDEDIR    - C header files for non-gcc (/usr/include)
        DATAROOTDIR      - read-only architecture-independent data root (share)
        DATADIR          - read-only architecture-independent data (DATAROOTDIR)
        INFODIR          - info documentation (DATAROOTDIR/info)
        LOCALEDIR        - locale-dependent data (DATAROOTDIR/locale)
        MANDIR          - man documentation (DATAROOTDIR/man)
        DOCDIR          - documentation root (DATAROOTDIR/doc/PROJECT_NAME)
 
      Each CMAKE_INSTALL_<dir> value may be passed to the DESTINATION
      options of install() commands for the corresponding file type.  If the
      includer does not define a value the above-shown default will be used
      and the value will appear in the cache for editing by the user.  Each
      CMAKE_INSTALL_FULL_<dir> value contains an absolute path constructed
      from the corresponding destination by prepending (if necessary) the
      value of CMAKE_INSTALL_PREFIX.
 
  GenerateExportHeader
      Function for generation of export macros for libraries
 
      This module provides the function GENERATE_EXPORT_HEADER() and the
      accompanying ADD_COMPILER_EXPORT_FLAGS() function.
 
      The GENERATE_EXPORT_HEADER function can be used to generate a file
      suitable for preprocessor inclusion which contains EXPORT macros to be
      used in library classes.
 
      GENERATE_EXPORT_HEADER( LIBRARY_TARGET
 
                    [BASE_NAME <base_name>]
                    [EXPORT_MACRO_NAME <export_macro_name>]
                    [EXPORT_FILE_NAME <export_file_name>]
                    [DEPRECATED_MACRO_NAME <deprecated_macro_name>]
                    [NO_EXPORT_MACRO_NAME <no_export_macro_name>]
                    [STATIC_DEFINE <static_define>]
                    [NO_DEPRECATED_MACRO_NAME <no_deprecated_macro_name>]
                    [DEFINE_NO_DEPRECATED]
                    [PREFIX_NAME <prefix_name>]
 
      )
 
      ADD_COMPILER_EXPORT_FLAGS( [<output_variable>] )
 
      By default GENERATE_EXPORT_HEADER() generates macro names in a file
      name determined by the name of the library.  The
      ADD_COMPILER_EXPORT_FLAGS function adds -fvisibility=hidden to
      CMAKE_CXX_FLAGS if supported, and is a no-op on Windows which does not
      need extra compiler flags for exporting support.  You may optionally
      pass a single argument to ADD_COMPILER_EXPORT_FLAGS that will be
      populated with the required CXX_FLAGS required to enable visibility
      support for the compiler/architecture in use.
 
      This means that in the simplest case, users of these functions will be
      equivalent to:
 
          add_compiler_export_flags()
          add_library(somelib someclass.cpp)
          generate_export_header(somelib)
          install(TARGETS somelib DESTINATION ${LIBRARY_INSTALL_DIR})
          install(FILES
          someclass.h
          ${PROJECT_BINARY_DIR}/somelib_export.h DESTINATION ${INCLUDE_INSTALL_DIR}
          )
 
     
 
      And in the ABI header files:
 
          #include "somelib_export.h"
          class SOMELIB_EXPORT SomeClass {
            ...
          };
 
     
 
      The CMake fragment will generate a file in the
      ${CMAKE_CURRENT_BUILD_DIR} called somelib_export.h containing the
      macros SOMELIB_EXPORT, SOMELIB_NO_EXPORT, SOMELIB_DEPRECATED,
      SOMELIB_DEPRECATED_EXPORT and SOMELIB_DEPRECATED_NO_EXPORT.  The
      resulting file should be installed with other headers in the library.
 
      The BASE_NAME argument can be used to override the file name and the
      names used for the macros
 
          add_library(somelib someclass.cpp)
          generate_export_header(somelib
            BASE_NAME other_name
          )
 
     
 
      Generates a file called other_name_export.h containing the macros
      OTHER_NAME_EXPORT, OTHER_NAME_NO_EXPORT and OTHER_NAME_DEPRECATED etc.
 
      The BASE_NAME may be overridden by specifiying other options in the
      function.  For example:
 
          add_library(somelib someclass.cpp)
          generate_export_header(somelib
            EXPORT_MACRO_NAME OTHER_NAME_EXPORT
          )
 
     
 
      creates the macro OTHER_NAME_EXPORT instead of SOMELIB_EXPORT, but
      other macros and the generated file name is as default.
 
          add_library(somelib someclass.cpp)
          generate_export_header(somelib
            DEPRECATED_MACRO_NAME KDE_DEPRECATED
          )
 
     
 
      creates the macro KDE_DEPRECATED instead of SOMELIB_DEPRECATED.
 
      If LIBRARY_TARGET is a static library, macros are defined without
      values.
 
      If the same sources are used to create both a shared and a static
      library, the uppercased symbol ${BASE_NAME}_STATIC_DEFINE should be
      used when building the static library
 
          add_library(shared_variant SHARED ${lib_SRCS})
          add_library(static_variant ${lib_SRCS})
          generate_export_header(shared_variant BASE_NAME libshared_and_static)
          set_target_properties(static_variant PROPERTIES
            COMPILE_FLAGS -DLIBSHARED_AND_STATIC_STATIC_DEFINE)
 
     
 
      This will cause the export macros to expand to nothing when building
      the static library.
 
      If DEFINE_NO_DEPRECATED is specified, then a macro
      ${BASE_NAME}_NO_DEPRECATED will be defined This macro can be used to
      remove deprecated code from preprocessor output.
 
          option(EXCLUDE_DEPRECATED "Exclude deprecated parts of the library" FALSE)
          if (EXCLUDE_DEPRECATED)
            set(NO_BUILD_DEPRECATED DEFINE_NO_DEPRECATED)
          endif()
          generate_export_header(somelib ${NO_BUILD_DEPRECATED})
 
     
 
      And then in somelib:
 
          class SOMELIB_EXPORT SomeClass
          {
          public:
          #ifndef SOMELIB_NO_DEPRECATED
            SOMELIB_DEPRECATED void oldMethod();
          #endif
          };
 
     
 
          #ifndef SOMELIB_NO_DEPRECATED
          void SomeClass::oldMethod() {  }
          #endif
 
     
 
      If PREFIX_NAME is specified, the argument will be used as a prefix to
      all generated macros.
 
      For example:
 
          generate_export_header(somelib PREFIX_NAME VTK_)
 
     
 
      Generates the macros VTK_SOMELIB_EXPORT etc.
 
  GetPrerequisites
      Functions to analyze and list executable file prerequisites.
 
      This module provides functions to list the .dll, .dylib or .so files
      that an executable or shared library file depends on.  (Its
      prerequisites.)
 
      It uses various tools to obtain the list of required shared library
      files:
 
          dumpbin (Windows)
          ldd (Linux/Unix)
          otool (Mac OSX)
 
      The following functions are provided by this module:
 
          get_prerequisites
          list_prerequisites
          list_prerequisites_by_glob
          gp_append_unique
          is_file_executable
          gp_item_default_embedded_path
            (projects can override with gp_item_default_embedded_path_override)
          gp_resolve_item
            (projects can override with gp_resolve_item_override)
          gp_resolved_file_type
            (projects can override with gp_resolved_file_type_override)
          gp_file_type
 
      Requires CMake 2.6 or greater because it uses function, break, return
      and PARENT_SCOPE.
 
        GET_PREREQUISITES(<target> <prerequisites_var> <exclude_system> <recurse>
                          <exepath> <dirs>)
 
      Get the list of shared library files required by <target>.  The list
      in the variable named <prerequisites_var> should be empty on first
      entry to this function.  On exit, <prerequisites_var> will contain the
      list of required shared library files.
 
      <target> is the full path to an executable file.  <prerequisites_var>
      is the name of a CMake variable to contain the results.
      <exclude_system> must be 0 or 1 indicating whether to include or
      exclude "system" prerequisites.  If <recurse> is set to 1 all
      prerequisites will be found recursively, if set to 0 only direct
      prerequisites are listed.  <exepath> is the path to the top level
      executable used for @executable_path replacment on the Mac.  <dirs> is
      a list of paths where libraries might be found: these paths are
      searched first when a target without any path info is given.  Then
      standard system locations are also searched: PATH, Framework
      locations, /usr/lib...
 
        LIST_PREREQUISITES(<target> [<recurse> [<exclude_system> [<verbose>]]])
 
      Print a message listing the prerequisites of <target>.
 
      <target> is the name of a shared library or executable target or the
      full path to a shared library or executable file.  If <recurse> is set
      to 1 all prerequisites will be found recursively, if set to 0 only
      direct prerequisites are listed.  <exclude_system> must be 0 or 1
      indicating whether to include or exclude "system" prerequisites.  With
      <verbose> set to 0 only the full path names of the prerequisites are
      printed, set to 1 extra informatin will be displayed.
 
        LIST_PREREQUISITES_BY_GLOB(<glob_arg> <glob_exp>)
 
      Print the prerequisites of shared library and executable files
      matching a globbing pattern.  <glob_arg> is GLOB or GLOB_RECURSE and
      <glob_exp> is a globbing expression used with "file(GLOB" or
      "file(GLOB_RECURSE" to retrieve a list of matching files.  If a
      matching file is executable, its prerequisites are listed.
 
      Any additional (optional) arguments provided are passed along as the
      optional arguments to the list_prerequisites calls.
 
        GP_APPEND_UNIQUE(<list_var> <value>)
 
      Append <value> to the list variable <list_var> only if the value is
      not already in the list.
 
        IS_FILE_EXECUTABLE(<file> <result_var>)
 
      Return 1 in <result_var> if <file> is a binary executable, 0
      otherwise.
 
        GP_ITEM_DEFAULT_EMBEDDED_PATH(<item> <default_embedded_path_var>)
 
      Return the path that others should refer to the item by when the item
      is embedded inside a bundle.
 
      Override on a per-project basis by providing a project-specific
      gp_item_default_embedded_path_override function.
 
        GP_RESOLVE_ITEM(<context> <item> <exepath> <dirs> <resolved_item_var>)
 
      Resolve an item into an existing full path file.
 
      Override on a per-project basis by providing a project-specific
      gp_resolve_item_override function.
 
        GP_RESOLVED_FILE_TYPE(<original_file> <file> <exepath> <dirs> <type_var>)
 
      Return the type of <file> with respect to <original_file>.  String
      describing type of prerequisite is returned in variable named
      <type_var>.
 
      Use <exepath> and <dirs> if necessary to resolve non-absolute <file>
      values -- but only for non-embedded items.
 
      Possible types are:
 
          system
          local
          embedded
          other
 
      Override on a per-project basis by providing a project-specific
      gp_resolved_file_type_override function.
 
        GP_FILE_TYPE(<original_file> <file> <type_var>)
 
      Return the type of <file> with respect to <original_file>.  String
      describing type of prerequisite is returned in variable named
      <type_var>.
 
      Possible types are:
 
          system
          local
          embedded
          other
 
 
  InstallRequiredSystemLibraries
       
 
      By including this file, all library files listed in the variable
      CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS will be installed with
      install(PROGRAMS ...) into bin for WIN32 and lib for non-WIN32.  If
      CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_SKIP is set to TRUE before including
      this file, then the INSTALL command is not called.  The user can use
      the variable CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS to use a custom install
      command and install them however they want.  If it is the MSVC
      compiler, then the microsoft run time libraries will be found and
      automatically added to the CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS, and
      installed.  If CMAKE_INSTALL_DEBUG_LIBRARIES is set and it is the MSVC
      compiler, then the debug libraries are installed when available.  If
      CMAKE_INSTALL_DEBUG_LIBRARIES_ONLY is set then only the debug
      libraries are installed when both debug and release are available.  If
      CMAKE_INSTALL_MFC_LIBRARIES is set then the MFC run time libraries are
      installed as well as the CRT run time libraries.  If
      CMAKE_INSTALL_SYSTEM_RUNTIME_DESTINATION is set then the libraries are
      installed to that directory rather than the default.  If
      CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_NO_WARNINGS is NOT set, then this
      file warns about required files that do not exist.  You can set this
      variable to ON before including this file to avoid the warning.  For
      example, the Visual Studio Express editions do not include the
      redistributable files, so if you include this file on a machine with
      only VS Express installed, you'll get the warning.
 
  MacroAddFileDependencies
      MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...)
 
      Using the macro MACRO_ADD_FILE_DEPENDENCIES() is discouraged.  There
      are usually better ways to specify the correct dependencies.
 
      MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...) is just a
      convenience wrapper around the OBJECT_DEPENDS source file property.
      You can just use set_property(SOURCE <file> APPEND PROPERTY
      OBJECT_DEPENDS depend_files) instead.
 
  ProcessorCount
      ProcessorCount(var)
 
      Determine the number of processors/cores and save value in ${var}
 
      Sets the variable named ${var} to the number of physical cores
      available on the machine if the information can be determined.
      Otherwise it is set to 0.  Currently this functionality is implemented
      for AIX, cygwin, FreeBSD, HPUX, IRIX, Linux, Mac OS X, QNX, Sun and
      Windows.
 
      This function is guaranteed to return a positive integer (>=1) if it
      succeeds.  It returns 0 if there's a problem determining the processor
      count.
 
      Example use, in a ctest -S dashboard script:
 
          include(ProcessorCount)
          ProcessorCount(N)
          if(NOT N EQUAL 0)
            set(CTEST_BUILD_FLAGS -j${N})
            set(ctest_test_args ${ctest_test_args} PARALLEL_LEVEL ${N})
          endif()
 
     
 
      This function is intended to offer an approximation of the value of
      the number of compute cores available on the current machine, such
      that you may use that value for parallel building and parallel
      testing.  It is meant to help utilize as much of the machine as seems
      reasonable.  Of course, knowledge of what else might be running on the
      machine simultaneously should be used when deciding whether to request
      a machine's full capacity all for yourself.
 
  Qt4ConfigDependentSettings
       
 
      This file is included by FindQt4.cmake, don't include it directly.

      This file is included by FindQt4.cmake, don't include it directly.
 
  SelectLibraryConfigurations
       
 
      select_library_configurations( basename )
 
      This macro takes a library base name as an argument, and will choose
      good values for basename_LIBRARY, basename_LIBRARIES,
      basename_LIBRARY_DEBUG, and basename_LIBRARY_RELEASE depending on what
      has been found and set.  If only basename_LIBRARY_RELEASE is defined,
      basename_LIBRARY, basename_LIBRARY_DEBUG, and basename_LIBRARY_RELEASE
      will be set to the release value.  If only basename_LIBRARY_DEBUG is
      defined, then basename_LIBRARY, basename_LIBRARY_DEBUG and
      basename_LIBRARY_RELEASE will take the debug value.
 
      If the generator supports configuration types, then basename_LIBRARY
      and basename_LIBRARIES will be set with debug and optimized flags
      specifying the library to be used for the given configuration.  If no
      build type has been set or the generator in use does not support
      configuration types, then basename_LIBRARY and basename_LIBRARIES will
      take only the release values.
 
  SquishTestScript
       
 
     
 
      This script launches a GUI test using Squish.  You should not call the
      script directly; instead, you should access it via the SQUISH_ADD_TEST
      macro that is defined in FindSquish.cmake.
 
      This script starts the Squish server, launches the test on the client,
      and finally stops the squish server.  If any of these steps fail
      (including if the tests do not pass) then a fatal error is raised.
 
 
  TestBigEndian
      Define macro to determine endian type
 
      Check if the system is big endian or little endian
 
        TEST_BIG_ENDIAN(VARIABLE)
        VARIABLE - variable to store the result to
 
     
 
 
  TestCXXAcceptsFlag
      Test CXX compiler for a flag
 
      Check if the CXX compiler accepts a flag
 
        Macro CHECK_CXX_ACCEPTS_FLAG(FLAGS VARIABLE) -
            checks if the function exists
        FLAGS - the flags to try
        VARIABLE - variable to store the result
 
     
 
 
  TestForANSIForScope
      Check for ANSI for scope support
 
      Check if the compiler restricts the scope of variables declared in a
      for-init-statement to the loop body.
 
        CMAKE_NO_ANSI_FOR_SCOPE - holds result
 
     
 
 
  TestForANSIStreamHeaders
      Test for compiler support of ANSI stream headers iostream, etc.

  UseEcos
      This module defines variables and macros required to build eCos
      application.
 
      This file contains the following macros:
      ECOS_ADD_INCLUDE_DIRECTORIES() - add the eCos include dirs
      ECOS_ADD_EXECUTABLE(name source1 ...  sourceN ) - create an eCos
      executable ECOS_ADJUST_DIRECTORY(VAR source1 ...  sourceN ) - adjusts
      the path of the source files and puts the result into VAR
 
      Macros for selecting the toolchain: ECOS_USE_ARM_ELF_TOOLS() - enable
      the ARM ELF toolchain for the directory where it is called
      ECOS_USE_I386_ELF_TOOLS() - enable the i386 ELF toolchain for the
      directory where it is called ECOS_USE_PPC_EABI_TOOLS() - enable the
      PowerPC toolchain for the directory where it is called
 
      It contains the following variables: ECOS_DEFINITIONS
      ECOSCONFIG_EXECUTABLE ECOS_CONFIG_FILE - defaults to ecos.ecc, if your
      eCos configuration file has a different name, adjust this variable for
      internal use only:
 
        ECOS_ADD_TARGET_LIB
 
 
  UseJava
      Use Module for Java
 
      This file provides functions for Java.  It is assumed that

      information on how to load Java into your CMake project.
 
      add_jar(TARGET_NAME SRC1 SRC2 ..  SRCN RCS1 RCS2 ..  RCSN)
 
      This command creates a <TARGET_NAME>.jar.  It compiles the given
      source files (SRC) and adds the given resource files (RCS) to the jar
      file.  If only resource files are given then just a jar file is
      created.
 
      Additional instructions:
 
          To add compile flags to the target you can set these flags with
          the following variable:
 
     
 
              set(CMAKE_JAVA_COMPILE_FLAGS -nowarn)
 
     
 
          To add a path or a jar file to the class path you can do this
          with the CMAKE_JAVA_INCLUDE_PATH variable.
 
     
 
              set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)
 
     
 
          To use a different output name for the target you can set it with:
 
     
 
              set(CMAKE_JAVA_TARGET_OUTPUT_NAME shibboleet.jar)
              add_jar(foobar foobar.java)
 
     
 
          To use a different output directory than CMAKE_CURRENT_BINARY_DIR
          you can set it with:
 
     
 
              set(CMAKE_JAVA_TARGET_OUTPUT_DIR ${PROJECT_BINARY_DIR}/bin)
 
     
 
          To define an entry point in your jar you can set it with:
 
     
 
              set(CMAKE_JAVA_JAR_ENTRY_POINT com/examples/MyProject/Main)
 
     
 
          To add a VERSION to the target output name you can set it using
          CMAKE_JAVA_TARGET_VERSION. This will create a jar file with the name
          shibboleet-1.0.0.jar and will create a symlink shibboleet.jar
          pointing to the jar with the version information.
 
     
 
              set(CMAKE_JAVA_TARGET_VERSION 1.2.0)
              add_jar(shibboleet shibbotleet.java)
 
     
 
          If the target is a JNI library, utilize the following commands to
          create a JNI symbolic link:
 
     
 
              set(CMAKE_JNI_TARGET TRUE)
              set(CMAKE_JAVA_TARGET_VERSION 1.2.0)
              add_jar(shibboleet shibbotleet.java)
              install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet)
              install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR})
 
     
 
          If a single target needs to produce more than one jar from its
          java source code, to prevent the accumulation of duplicate class
          files in subsequent jars, set/reset CMAKE_JAR_CLASSES_PREFIX prior
          to calling the add_jar() function:
 
     
 
              set(CMAKE_JAR_CLASSES_PREFIX com/redhat/foo)
              add_jar(foo foo.java)
 
     
 
              set(CMAKE_JAR_CLASSES_PREFIX com/redhat/bar)
              add_jar(bar bar.java)
 
     
 
      Target Properties:
 
          The add_jar() functions sets some target properties. You can get these
          properties with the
            get_property(TARGET <target_name> PROPERTY <propery_name>)
          command.
 
     
 
          INSTALL_FILES      The files which should be installed. This is used by
                            install_jar().
          JNI_SYMLINK        The JNI symlink which should be installed.
                            This is used by install_jni_symlink().
          JAR_FILE          The location of the jar file so that you can include
                            it.
          CLASS_DIR          The directory where the class files can be found. For
                            example to use them with javah.
 
     
 
      find_jar(<VAR>
 
                name | NAMES name1 [name2 ...]
                [PATHS path1 [path2 ... ENV var]]
                [VERSIONS version1 [version2]]
                [DOC "cache documentation string"]
                )
 
     
 
      This command is used to find a full path to the named jar.  A cache
      entry named by <VAR> is created to stor the result of this command.
      If the full path to a jar is found the result is stored in the
      variable and the search will not repeated unless the variable is
      cleared.  If nothing is found, the result will be <VAR>-NOTFOUND, and
      the search will be attempted again next time find_jar is invoked with
      the same variable.  The name of the full path to a file that is
      searched for is specified by the names listed after NAMES argument.
      Additional search locations can be specified after the PATHS argument.
      If you require special a version of a jar file you can specify it with
      the VERSIONS argument.  The argument after DOC will be used for the
      documentation string in the cache.
 
      install_jar(TARGET_NAME DESTINATION)
 
      This command installs the TARGET_NAME files to the given DESTINATION.
      It should be called in the same scope as add_jar() or it will fail.
 
      install_jni_symlink(TARGET_NAME DESTINATION)
 
      This command installs the TARGET_NAME JNI symlinks to the given
      DESTINATION.  It should be called in the same scope as add_jar() or it
      will fail.
 
      create_javadoc(<VAR>
 
                      PACKAGES pkg1 [pkg2 ...]
                      [SOURCEPATH <sourcepath>]

                      [VERSION TRUE|FALSE]
                      )
 
     
 
      Create java documentation based on files or packages.  For more
      details please read the javadoc manpage.
 
      There are two main signatures for create_javadoc.  The first signature
      works with package names on a path with source files:
 
          Example:
          create_javadoc(my_example_doc
            PACKAGES com.exmaple.foo com.example.bar
            SOURCEPATH "${CMAKE_CURRENT_SOURCE_DIR}"
            CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
            WINDOWTITLE "My example"
            DOCTITLE "<h1>My example</h1>"
            AUTHOR TRUE
            USE TRUE
            VERSION TRUE
          )
 
     
 
      The second signature for create_javadoc works on a given list of
      files.
 
          create_javadoc(<VAR>
                        FILES file1 [file2 ...]
                        [CLASSPATH <classpath>]
                        [INSTALLPATH <install path>]
                        [DOCTITLE "the documentation title"]
                        [WINDOWTITLE "the title of the document"]
                        [AUTHOR TRUE|FALSE]
                        [USE TRUE|FALSE]
                        [VERSION TRUE|FALSE]
                        )
 
     
 
      Example:
 
          create_javadoc(my_example_doc
            FILES ${example_SRCS}
            CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
            WINDOWTITLE "My example"
            DOCTITLE "<h1>My example</h1>"
            AUTHOR TRUE
            USE TRUE
            VERSION TRUE
          )
 
     
 
      Both signatures share most of the options.  These options are the same
      as what you can find in the javadoc manpage.  Please look at the
      manpage for CLASSPATH, DOCTITLE, WINDOWTITLE, AUTHOR, USE and VERSION.
 
      The documentation will be by default installed to
 
          ${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR>
 
     
 
      if you don't set the INSTALLPATH.
 
 
  UseJavaClassFilelist
       
 
     
 
      This script create a list of compiled Java class files to be added to

  UsePkgConfig
      Obsolete pkg-config module for CMake, use FindPkgConfig instead.
 
     
 
      This module defines the following macro:
 
      PKGCONFIG(package includedir libdir linkflags cflags)
 
      Calling PKGCONFIG will fill the desired information into the 4 given
      arguments, e.g.  PKGCONFIG(libart-2.0 LIBART_INCLUDE_DIR
      LIBART_LINK_DIR LIBART_LINK_FLAGS LIBART_CFLAGS) if pkg-config was NOT
      found or the specified software package doesn't exist, the variable
      will be empty when the function returns, otherwise they will contain
      the respective information
 
 
  UseQt4
      Use Module for QT4
 
      Sets up C and C++ to use Qt 4.  It is assumed that FindQt.cmake has
      already been loaded.  See FindQt.cmake for information on how to load
      Qt 4 into your CMake project.
 
  UseSWIG
      SWIG module for CMake
 
      Defines the following macros:
 
          SWIG_ADD_MODULE(name language [ files ])
            - Define swig module with given name and specified language
          SWIG_LINK_LIBRARIES(name [ libraries ])
            - Link libraries to swig module
 
      All other macros are for internal use only.  To get the actual name of
      the swig module, use: ${SWIG_MODULE_${name}_REAL_NAME}.  Set Source
      files properties such as CPLUSPLUS and SWIG_FLAGS to specify special
      behavior of SWIG.  Also global CMAKE_SWIG_FLAGS can be used to add
      special flags to all swig calls.  Another special variable is
      CMAKE_SWIG_OUTDIR, it allows one to specify where to write all the
      swig generated module (swig -outdir option) The name-specific variable
      SWIG_MODULE_<name>_EXTRA_DEPS may be used to specify extra
      dependencies for the generated modules.  If the source file generated
      by swig need some special flag you can use
      set_source_files_properties( ${swig_generated_file_fullname}
 
              PROPERTIES COMPILE_FLAGS "-bla")

Policies
 
  CMP0000
      A minimum required CMake version must be specified.
 
      CMake requires that projects specify the version of CMake to which
      they have been written.  This policy has been put in place so users
      trying to build the project may be told when they need to update their
      CMake.  Specifying a version also helps the project build with CMake
      versions newer than that specified.  Use the cmake_minimum_required
      command at the top of your main CMakeLists.txt file:
 
        cmake_minimum_required(VERSION <major>.<minor>)
 
      where "<major>.<minor>" is the version of CMake you want to support
      (such as "2.6").  The command will ensure that at least the given
      version of CMake is running and help newer versions be compatible with
      the project.  See documentation of cmake_minimum_required for details.
 
      Note that the command invocation must appear in the CMakeLists.txt
      file itself; a call in an included file is not sufficient.  However,
      the cmake_policy command may be called to set policy CMP0000 to OLD or
      NEW behavior explicitly.  The OLD behavior is to silently ignore the
      missing invocation.  The NEW behavior is to issue an error instead of
      a warning.  An included file may set CMP0000 explicitly to affect how
      this policy is enforced for the main CMakeLists.txt file.
 
      This policy was introduced in CMake version 2.6.0.
 
  CMP0001
      CMAKE_BACKWARDS_COMPATIBILITY should no longer be used.
 
      The OLD behavior is to check CMAKE_BACKWARDS_COMPATIBILITY and present
      it to the user.  The NEW behavior is to ignore
      CMAKE_BACKWARDS_COMPATIBILITY completely.
 
      In CMake 2.4 and below the variable CMAKE_BACKWARDS_COMPATIBILITY was
      used to request compatibility with earlier versions of CMake.  In
      CMake 2.6 and above all compatibility issues are handled by policies
      and the cmake_policy command.  However, CMake must still check
      CMAKE_BACKWARDS_COMPATIBILITY for projects written for CMake 2.4 and
      below.
 
      This policy was introduced in CMake version 2.6.0.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0002
      Logical target names must be globally unique.
 
      Targets names created with add_executable, add_library, or
      add_custom_target are logical build target names.  Logical target
      names must be globally unique because:
 
        - Unique names may be referenced unambiguously both in CMake
          code and on make tool command lines.
        - Logical names are used by Xcode and VS IDE generators
          to produce meaningful project names for the targets.
 
      The logical name of executable and library targets does not have to
      correspond to the physical file names built.  Consider using the
      OUTPUT_NAME target property to create two targets with the same
      physical name while keeping logical names distinct.  Custom targets
      must simply have globally unique names (unless one uses the global
      property ALLOW_DUPLICATE_CUSTOM_TARGETS with a Makefiles generator).
 
      This policy was introduced in CMake version 2.6.0.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0003
      Libraries linked via full path no longer produce linker search paths.
 
      This policy affects how libraries whose full paths are NOT known are
      found at link time, but was created due to a change in how CMake deals
      with libraries whose full paths are known.  Consider the code
 
        target_link_libraries(myexe /path/to/libA.so)
 
      CMake 2.4 and below implemented linking to libraries whose full paths
      are known by splitting them on the link line into separate components
      consisting of the linker search path and the library name.  The
      example code might have produced something like
 
        ... -L/path/to -lA ...
 
      in order to link to library A.  An analysis was performed to order
      multiple link directories such that the linker would find library A in
      the desired location, but there are cases in which this does not work.
      CMake versions 2.6 and above use the more reliable approach of passing
      the full path to libraries directly to the linker in most cases.  The
      example code now produces something like
 
        ... /path/to/libA.so ....
 
      Unfortunately this change can break code like
 
        target_link_libraries(myexe /path/to/libA.so B)
 
      where "B" is meant to find "/path/to/libB.so".  This code is wrong
      because the user is asking the linker to find library B but has not
      provided a linker search path (which may be added with the
      link_directories command).  However, with the old linking
      implementation the code would work accidentally because the linker
      search path added for library A allowed library B to be found.
 
      In order to support projects depending on linker search paths added by
      linking to libraries with known full paths, the OLD behavior for this
      policy will add the linker search paths even though they are not
      needed for their own libraries.  When this policy is set to OLD, CMake
      will produce a link line such as
 
        ... -L/path/to /path/to/libA.so -lB ...
 
      which will allow library B to be found as it was previously.  When
      this policy is set to NEW, CMake will produce a link line such as
 
        ... /path/to/libA.so -lB ...
 
      which more accurately matches what the project specified.
 
      The setting for this policy used when generating the link line is that
      in effect when the target is created by an add_executable or
      add_library command.  For the example described above, the code
 
        cmake_policy(SET CMP0003 OLD) # or cmake_policy(VERSION 2.4)
        add_executable(myexe myexe.c)
        target_link_libraries(myexe /path/to/libA.so B)
 
      will work and suppress the warning for this policy.  It may also be
      updated to work with the corrected linking approach:
 
        cmake_policy(SET CMP0003 NEW) # or cmake_policy(VERSION 2.6)
        link_directories(/path/to) # needed to find library B
        add_executable(myexe myexe.c)
        target_link_libraries(myexe /path/to/libA.so B)
 
      Even better, library B may be specified with a full path:
 
        add_executable(myexe myexe.c)
        target_link_libraries(myexe /path/to/libA.so /path/to/libB.so)
 
      When all items on the link line have known paths CMake does not check
      this policy so it has no effect.
 
      Note that the warning for this policy will be issued for at most one
      target.  This avoids flooding users with messages for every target
      when setting the policy once will probably fix all targets.
 
      This policy was introduced in CMake version 2.6.0.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0004
      Libraries linked may not have leading or trailing whitespace.
 
      CMake versions 2.4 and below silently removed leading and trailing
      whitespace from libraries linked with code like
 
        target_link_libraries(myexe " A ")
 
      This could lead to subtle errors in user projects.
 
      The OLD behavior for this policy is to silently remove leading and
      trailing whitespace.  The NEW behavior for this policy is to diagnose
      the existence of such whitespace as an error.  The setting for this
      policy used when checking the library names is that in effect when the
      target is created by an add_executable or add_library command.
 
      This policy was introduced in CMake version 2.6.0.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0005
      Preprocessor definition values are now escaped automatically.
 
      This policy determines whether or not CMake should generate escaped
      preprocessor definition values added via add_definitions.  CMake
      versions 2.4 and below assumed that only trivial values would be given
      for macros in add_definitions calls.  It did not attempt to escape
      non-trivial values such as string literals in generated build rules.
      CMake versions 2.6 and above support escaping of most values, but
      cannot assume the user has not added escapes already in an attempt to
      work around limitations in earlier versions.
 
      The OLD behavior for this policy is to place definition values given
      to add_definitions directly in the generated build rules without
      attempting to escape anything.  The NEW behavior for this policy is to
      generate correct escapes for all native build tools automatically.
      See documentation of the COMPILE_DEFINITIONS target property for
      limitations of the escaping implementation.
 
      This policy was introduced in CMake version 2.6.0.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0006
      Installing MACOSX_BUNDLE targets requires a BUNDLE DESTINATION.
 
      This policy determines whether the install(TARGETS) command must be
      given a BUNDLE DESTINATION when asked to install a target with the
      MACOSX_BUNDLE property set.  CMake 2.4 and below did not distinguish
      application bundles from normal executables when installing targets.
      CMake 2.6 provides a BUNDLE option to the install(TARGETS) command
      that specifies rules specific to application bundles on the Mac.
      Projects should use this option when installing a target with the
      MACOSX_BUNDLE property set.
 
      The OLD behavior for this policy is to fall back to the RUNTIME
      DESTINATION if a BUNDLE DESTINATION is not given.  The NEW behavior
      for this policy is to produce an error if a bundle target is installed
      without a BUNDLE DESTINATION.
 
      This policy was introduced in CMake version 2.6.0.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0007
      list command no longer ignores empty elements.
 
      This policy determines whether the list command will ignore empty
      elements in the list.  CMake 2.4 and below list commands ignored all
      empty elements in the list.  For example, a;b;;c would have length 3
      and not 4.  The OLD behavior for this policy is to ignore empty list
      elements.  The NEW behavior for this policy is to correctly count
      empty elements in a list.
 
      This policy was introduced in CMake version 2.6.0.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0008
      Libraries linked by full-path must have a valid library file name.
 
      In CMake 2.4 and below it is possible to write code like
 
        target_link_libraries(myexe /full/path/to/somelib)
 
      where "somelib" is supposed to be a valid library file name such as
      "libsomelib.a" or "somelib.lib".  For Makefile generators this
      produces an error at build time because the dependency on the full
      path cannot be found.  For VS IDE and Xcode generators this used to
      work by accident because CMake would always split off the library
      directory and ask the linker to search for the library by name
      (-lsomelib or somelib.lib).  Despite the failure with Makefiles, some
      projects have code like this and build only with VS and/or Xcode.
      This version of CMake prefers to pass the full path directly to the
      native build tool, which will fail in this case because it does not
      name a valid library file.
 
      This policy determines what to do with full paths that do not appear
      to name a valid library file.  The OLD behavior for this policy is to
      split the library name from the path and ask the linker to search for
      it.  The NEW behavior for this policy is to trust the given path and
      pass it directly to the native build tool unchanged.
 
      This policy was introduced in CMake version 2.6.1.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0009
      FILE GLOB_RECURSE calls should not follow symlinks by default.
 
      In CMake 2.6.1 and below, FILE GLOB_RECURSE calls would follow through
      symlinks, sometimes coming up with unexpectedly large result sets
      because of symlinks to top level directories that contain hundreds of
      thousands of files.
 
      This policy determines whether or not to follow symlinks encountered
      during a FILE GLOB_RECURSE call.  The OLD behavior for this policy is
      to follow the symlinks.  The NEW behavior for this policy is not to
      follow the symlinks by default, but only if FOLLOW_SYMLINKS is given
      as an additional argument to the FILE command.
 
      This policy was introduced in CMake version 2.6.2.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0010
      Bad variable reference syntax is an error.
 
      In CMake 2.6.2 and below, incorrect variable reference syntax such as
      a missing close-brace ("${FOO") was reported but did not stop
      processing of CMake code.  This policy determines whether a bad
      variable reference is an error.  The OLD behavior for this policy is
      to warn about the error, leave the string untouched, and continue.
      The NEW behavior for this policy is to report an error.
 
      This policy was introduced in CMake version 2.6.3.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0011
      Included scripts do automatic cmake_policy PUSH and POP.
 
      In CMake 2.6.2 and below, CMake Policy settings in scripts loaded by
      the include() and find_package() commands would affect the includer.
      Explicit invocations of cmake_policy(PUSH) and cmake_policy(POP) were
      required to isolate policy changes and protect the includer.  While
      some scripts intend to affect the policies of their includer, most do
      not.  In CMake 2.6.3 and above, include() and find_package() by
      default PUSH and POP an entry on the policy stack around an included
      script, but provide a NO_POLICY_SCOPE option to disable it.  This
      policy determines whether or not to imply NO_POLICY_SCOPE for
      compatibility.  The OLD behavior for this policy is to imply
      NO_POLICY_SCOPE for include() and find_package() commands.  The NEW
      behavior for this policy is to allow the commands to do their default
      cmake_policy PUSH and POP.
 
      This policy was introduced in CMake version 2.6.3.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0012
      if() recognizes numbers and boolean constants.
 
      In CMake versions 2.6.4 and lower the if() command implicitly
      dereferenced arguments corresponding to variables, even those named
      like numbers or boolean constants, except for 0 and 1.  Numbers and
      boolean constants such as true, false, yes, no, on, off, y, n,
      notfound, ignore (all case insensitive) were recognized in some cases
      but not all.  For example, the code "if(TRUE)" might have evaluated as
      false.  Numbers such as 2 were recognized only in boolean expressions
      like "if(NOT 2)" (leading to false) but not as a single-argument like
      "if(2)" (also leading to false).  Later versions of CMake prefer to
      treat numbers and boolean constants literally, so they should not be
      used as variable names.
 
      The OLD behavior for this policy is to implicitly dereference
      variables named like numbers and boolean constants.  The NEW behavior
      for this policy is to recognize numbers and boolean constants without
      dereferencing variables with such names.
 
      This policy was introduced in CMake version 2.8.0.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0013
      Duplicate binary directories are not allowed.
 
      CMake 2.6.3 and below silently permitted add_subdirectory() calls to
      create the same binary directory multiple times.  During build system
      generation files would be written and then overwritten in the build
      tree and could lead to strange behavior.  CMake 2.6.4 and above
      explicitly detect duplicate binary directories.  CMake 2.6.4 always
      considers this case an error.  In CMake 2.8.0 and above this policy
      determines whether or not the case is an error.  The OLD behavior for
      this policy is to allow duplicate binary directories.  The NEW
      behavior for this policy is to disallow duplicate binary directories
      with an error.
 
      This policy was introduced in CMake version 2.8.0.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0014
      Input directories must have CMakeLists.txt.
 
      CMake versions before 2.8 silently ignored missing CMakeLists.txt
      files in directories referenced by add_subdirectory() or subdirs(),
      treating them as if present but empty.  In CMake 2.8.0 and above this
      policy determines whether or not the case is an error.  The OLD
      behavior for this policy is to silently ignore the problem.  The NEW
      behavior for this policy is to report an error.
 
      This policy was introduced in CMake version 2.8.0.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0015
      link_directories() treats paths relative to the source dir.
 
      In CMake 2.8.0 and lower the link_directories() command passed
      relative paths unchanged to the linker.  In CMake 2.8.1 and above the
      link_directories() command prefers to interpret relative paths with
      respect to CMAKE_CURRENT_SOURCE_DIR, which is consistent with
      include_directories() and other commands.  The OLD behavior for this
      policy is to use relative paths verbatim in the linker command.  The
      NEW behavior for this policy is to convert relative paths to absolute
      paths by appending the relative path to CMAKE_CURRENT_SOURCE_DIR.
 
      This policy was introduced in CMake version 2.8.1.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0016
      target_link_libraries() reports error if only argument is not a
      target.
 
      In CMake 2.8.2 and lower the target_link_libraries() command silently
      ignored if it was called with only one argument, and this argument
      wasn't a valid target.  In CMake 2.8.3 and above it reports an error
      in this case.
 
      This policy was introduced in CMake version 2.8.3.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0017
      Prefer files from the CMake module directory when including from
      there.
 
      Starting with CMake 2.8.4, if a cmake-module shipped with CMake (i.e.
      located in the CMake module directory) calls include() or
      find_package(), the files located in the the CMake module directory
      are preferred over the files in CMAKE_MODULE_PATH.  This makes sure
      that the modules belonging to CMake always get those files included
      which they expect, and against which they were developed and tested.
      In call other cases, the files found in CMAKE_MODULE_PATH still take
      precedence over the ones in the CMake module directory.  The OLD
      behaviour is to always prefer files from CMAKE_MODULE_PATH over files
      from the CMake modules directory.
 
      This policy was introduced in CMake version 2.8.4.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0018
      Ignore CMAKE_SHARED_LIBRARY_<Lang>_FLAGS variable.
 
      CMake 2.8.8 and lower compiled sources in SHARED and MODULE libraries
      using the value of the undocumented CMAKE_SHARED_LIBRARY_<Lang>_FLAGS
      platform variable.  The variable contained platform-specific flags
      needed to compile objects for shared libraries.  Typically it included
      a flag such as -fPIC for position independent code but also included
      other flags needed on certain platforms.  CMake 2.8.9 and higher
      prefer instead to use the POSITION_INDEPENDENT_CODE target property to
      determine what targets should be position independent, and new
      undocumented platform variables to select flags while ignoring
      CMAKE_SHARED_LIBRARY_<Lang>_FLAGS completely.
 
      The default for either approach produces identical compilation flags,
      but if a project modifies CMAKE_SHARED_LIBRARY_<Lang>_FLAGS from its
      original value this policy determines which approach to use.
 
      The OLD behavior for this policy is to ignore the
      POSITION_INDEPENDENT_CODE property for all targets and use the
      modified value of CMAKE_SHARED_LIBRARY_<Lang>_FLAGS for SHARED and
      MODULE libraries.
 
      The NEW behavior for this policy is to ignore
      CMAKE_SHARED_LIBRARY_<Lang>_FLAGS whether it is modified or not and
      honor the POSITION_INDEPENDENT_CODE target property.
 
      This policy was introduced in CMake version 2.8.9.  CMake version
      2.8.10 warns when the policy is not set and uses OLD behavior.  Use
      the cmake_policy command to set it to OLD or NEW explicitly.
 
------------------------------------------------------------------------------
Variables
 
------------------------------------------------------------------------------
Variables That Change Behavior
 
  BUILD_SHARED_LIBS
      Global flag to cause add_library to create shared libraries if on.
 
      If present and true, this will cause all libraries to be built shared
      unless the library was explicitly added as a static library.  This
      variable is often added to projects as an OPTION so that each user of
      a project can decide if they want to build the project using shared or
      static libraries.
 
  CMAKE_ABSOLUTE_DESTINATION_FILES
      List of files which have been installed using an ABSOLUTE DESTINATION
      path.
 
      This variable is defined by CMake-generated cmake_install.cmake
      scripts.  It can be used (read-only) by program or script that source
      those install scripts.  This is used by some CPack generators (e.g.
      RPM).
 
  CMAKE_AUTOMOC_RELAXED_MODE
      Switch between strict and relaxed automoc mode.
 
      By default, automoc behaves exactly as described in the documentation
      of the AUTOMOC target property.  When set to TRUE, it accepts more
      input and tries to find the correct input file for moc even if it
      differs from the documented behaviour.  In this mode it e.g.  also
      checks whether a header file is intended to be processed by moc when a
      "foo.moc" file has been included.
 
      Relaxed mode has to be enabled for KDE4 compatibility.
 
  CMAKE_BACKWARDS_COMPATIBILITY
      Version of cmake required to build project
 
      From the point of view of backwards compatibility, this specifies what
      version of CMake should be supported.  By default this value is the
      version number of CMake that you are running.  You can set this to an
      older version of CMake to support deprecated commands of CMake in
      projects that were written to use older versions of CMake.  This can
      be set by the user or set at the beginning of a CMakeLists file.
 
  CMAKE_BUILD_TYPE
      Specifies the build type for make based generators.
 
      This specifies what build type will be built in this tree.  Possible
      values are empty, Debug, Release, RelWithDebInfo and MinSizeRel.  This
      variable is only supported for make based generators.  If this
      variable is supported, then CMake will also provide initial values for
      the variables with the name
      CMAKE_C_FLAGS_[DEBUG|RELEASE|RELWITHDEBINFO|MINSIZEREL].  For example,
      if CMAKE_BUILD_TYPE is Debug, then CMAKE_C_FLAGS_DEBUG will be added
      to the CMAKE_C_FLAGS.
 
  CMAKE_COLOR_MAKEFILE
      Enables color output when using the Makefile generator.
 
      When enabled, the generated Makefiles will produce colored output.
      Default is ON.
 
  CMAKE_CONFIGURATION_TYPES
      Specifies the available build types.
 
      This specifies what build types will be available such as Debug,
      Release, RelWithDebInfo etc.  This has reasonable defaults on most
      platforms.  But can be extended to provide other build types.  See
      also CMAKE_BUILD_TYPE.
 
  CMAKE_DISABLE_FIND_PACKAGE_<PackageName>
      Variable for disabling find_package() calls.
 
      Every non-REQUIRED find_package() call in a project can be disabled by
      setting the variable CMAKE_DISABLE_FIND_PACKAGE_<PackageName> to TRUE.
      This can be used to build a project without an optional package,
      although that package is installed.
 
      This switch should be used during the initial CMake run.  Otherwise if
      the package has already been found in a previous CMake run, the
      variables which have been stored in the cache will still be there.  In
      the case it is recommended to remove the cache variables for this
      package from the cache using the cache editor or cmake -U
 
  CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION
      Ask cmake_install.cmake script to error out as soon as a file with
      absolute INSTALL DESTINATION is encountered.
 
      The fatal error is emitted before the installation of the offending
      file takes place.  This variable is used by CMake-generated
      cmake_install.cmake scripts.  If ones set this variable to ON while
      running the script, it may get fatal error messages from the script.
 
  CMAKE_FIND_LIBRARY_PREFIXES
      Prefixes to prepend when looking for libraries.
 
      This specifies what prefixes to add to library names when the
      find_library command looks for libraries.  On UNIX systems this is
      typically lib, meaning that when trying to find the foo library it
      will look for libfoo.
 
  CMAKE_FIND_LIBRARY_SUFFIXES
      Suffixes to append when looking for libraries.
 
      This specifies what suffixes to add to library names when the
      find_library command looks for libraries.  On Windows systems this is
      typically .lib and .dll, meaning that when trying to find the foo
      library it will look for foo.dll etc.
 
  CMAKE_FIND_PACKAGE_WARN_NO_MODULE
      Tell find_package to warn if called without an explicit mode.
 
      If find_package is called without an explicit mode option (MODULE,
      CONFIG or NO_MODULE) and no Find<pkg>.cmake module is in
      CMAKE_MODULE_PATH then CMake implicitly assumes that the caller
      intends to search for a package configuration file.  If no package
      configuration file is found then the wording of the failure message
      must account for both the case that the package is really missing and
      the case that the project has a bug and failed to provide the intended
      Find module.  If instead the caller specifies an explicit mode option
      then the failure message can be more specific.
 
      Set CMAKE_FIND_PACKAGE_WARN_NO_MODULE to TRUE to tell find_package to
      warn when it implicitly assumes Config mode.  This helps developers
      enforce use of an explicit mode in all calls to find_package within a
      project.
 
  CMAKE_IGNORE_PATH
      Path to be ignored by FIND_XXX() commands.
 
      Specifies directories to be ignored by searches in FIND_XXX()
      commands.  This is useful in cross-compiled environments where some
      system directories contain incompatible but possibly linkable
      libraries.  For example, on cross-compiled cluster environments, this
      allows a user to ignore directories containing libraries meant for the
      front-end machine that modules like FindX11 (and others) would
      normally search.  By default this is empty; it is intended to be set
      by the project.  Note that CMAKE_IGNORE_PATH takes a list of directory
      names, NOT a list of prefixes.  If you want to ignore paths under
      prefixes (bin, include, lib, etc.), you'll need to specify them
      explicitly.  See also CMAKE_PREFIX_PATH, CMAKE_LIBRARY_PATH,
      CMAKE_INCLUDE_PATH, CMAKE_PROGRAM_PATH.
 
  CMAKE_INCLUDE_PATH
      Path used for searching by FIND_FILE() and FIND_PATH().
 
      Specifies a path which will be used both by FIND_FILE() and
      FIND_PATH().  Both commands will check each of the contained
      directories for the existence of the file which is currently searched.
      By default it is empty, it is intended to be set by the project.  See
      also CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_PREFIX_PATH.
 
  CMAKE_INSTALL_DEFAULT_COMPONENT_NAME
      Default component used in install() commands.
 
      If an install() command is used without the COMPONENT argument, these
      files will be grouped into a default component.  The name of this
      default install component will be taken from this variable.  It
      defaults to "Unspecified".
 
  CMAKE_INSTALL_PREFIX
      Install directory used by install.
 
      If "make install" is invoked or INSTALL is built, this directory is
      pre-pended onto all install directories.  This variable defaults to
      /usr/local on UNIX and c:/Program Files on Windows.
 
      On UNIX one can use the DESTDIR mechanism in order to relocate the
      whole installation.  DESTDIR means DESTination DIRectory.  It is
      commonly used by makefile users in order to install software at
      non-default location.  It is usually invoked like this:
 
        make DESTDIR=/home/john install
 
      which will install the concerned software using the installation
      prefix, e.g.  "/usr/local" pre-pended with the DESTDIR value which
      finally gives "/home/john/usr/local".
 
      WARNING: DESTDIR may not be used on Windows because installation
      prefix usually contains a drive letter like in "C:/Program Files"
      which cannot be pre-pended with some other prefix.
 
  CMAKE_LIBRARY_PATH
      Path used for searching by FIND_LIBRARY().
 
      Specifies a path which will be used by FIND_LIBRARY().  FIND_LIBRARY()
      will check each of the contained directories for the existence of the
      library which is currently searched.  By default it is empty, it is
      intended to be set by the project.  See also
      CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_PREFIX_PATH.
 
  CMAKE_MFC_FLAG
      Tell cmake to use MFC for an executable or dll.
 
      This can be set in a CMakeLists.txt file and will enable MFC in the
      application.  It should be set to 1 for the static MFC library, and 2
      for the shared MFC library.  This is used in Visual Studio 6 and 7
      project files.  The CMakeSetup dialog used MFC and the CMakeLists.txt
      looks like this:
 
        add_definitions(-D_AFXDLL)
        set(CMAKE_MFC_FLAG 2)
        add_executable(CMakeSetup WIN32 ${SRCS})
 
 
  CMAKE_MODULE_PATH
      List of directories to search for CMake modules.
 
      Commands like include() and find_package() search for files in
      directories listed by this variable before checking the default
      modules that come with CMake.
 
  CMAKE_NOT_USING_CONFIG_FLAGS
      Skip _BUILD_TYPE flags if true.
 
      This is an internal flag used by the generators in CMake to tell CMake
      to skip the _BUILD_TYPE flags.
 
  CMAKE_POLICY_DEFAULT_CMP<NNNN>
      Default for CMake Policy CMP<NNNN> when it is otherwise left unset.
 
      Commands cmake_minimum_required(VERSION) and cmake_policy(VERSION) by
      default leave policies introduced after the given version unset.  Set
      CMAKE_POLICY_DEFAULT_CMP<NNNN> to OLD or NEW to specify the default
      for policy CMP<NNNN>, where <NNNN> is the policy number.
 
      This variable should not be set by a project in CMake code; use
      cmake_policy(SET) instead.  Users running CMake may set this variable
      in the cache (e.g.  -DCMAKE_POLICY_DEFAULT_CMP<NNNN>=<OLD|NEW>) to set
      a policy not otherwise set by the project.  Set to OLD to quiet a
      policy warning while using old behavior or to NEW to try building the
      project with new behavior.
 
  CMAKE_PREFIX_PATH
      Path used for searching by FIND_XXX(), with appropriate suffixes
      added.
 
      Specifies a path which will be used by the FIND_XXX() commands.  It
      contains the "base" directories, the FIND_XXX() commands append
      appropriate subdirectories to the base directories.  So FIND_PROGRAM()
      adds /bin to each of the directories in the path, FIND_LIBRARY()
      appends /lib to each of the directories, and FIND_PATH() and
      FIND_FILE() append /include .  By default it is empty, it is intended
      to be set by the project.  See also CMAKE_SYSTEM_PREFIX_PATH,
      CMAKE_INCLUDE_PATH, CMAKE_LIBRARY_PATH, CMAKE_PROGRAM_PATH.
 
  CMAKE_PROGRAM_PATH
      Path used for searching by FIND_PROGRAM().
 
      Specifies a path which will be used by FIND_PROGRAM().  FIND_PROGRAM()
      will check each of the contained directories for the existence of the
      program which is currently searched.  By default it is empty, it is
      intended to be set by the project.  See also
      CMAKE_SYSTEM_PROGRAM_PATH, CMAKE_PREFIX_PATH.
 
  CMAKE_SKIP_INSTALL_ALL_DEPENDENCY
      Don't make the install target depend on the all target.
 
      By default, the "install" target depends on the "all" target.  This
      has the effect, that when "make install" is invoked or INSTALL is
      built, first the "all" target is built, then the installation starts.
      If CMAKE_SKIP_INSTALL_ALL_DEPENDENCY is set to TRUE, this dependency
      is not created, so the installation process will start immediately,
      independent from whether the project has been completely built or not.
 
  CMAKE_SYSTEM_IGNORE_PATH
      Path to be ignored by FIND_XXX() commands.
 
      Specifies directories to be ignored by searches in FIND_XXX()
      commands.  This is useful in cross-compiled environments where some
      system directories contain incompatible but possibly linkable
      libraries.  For example, on cross-compiled cluster environments, this
      allows a user to ignore directories containing libraries meant for the
      front-end machine that modules like FindX11 (and others) would
      normally search.  By default this contains a list of directories
      containing incompatible binaries for the host system.  See also
      CMAKE_SYSTEM_PREFIX_PATH, CMAKE_SYSTEM_LIBRARY_PATH,
      CMAKE_SYSTEM_INCLUDE_PATH, and CMAKE_SYSTEM_PROGRAM_PATH.
 
  CMAKE_SYSTEM_INCLUDE_PATH
      Path used for searching by FIND_FILE() and FIND_PATH().
 
      Specifies a path which will be used both by FIND_FILE() and
      FIND_PATH().  Both commands will check each of the contained
      directories for the existence of the file which is currently searched.
      By default it contains the standard directories for the current
      system.  It is NOT intended to be modified by the project, use
      CMAKE_INCLUDE_PATH for this.  See also CMAKE_SYSTEM_PREFIX_PATH.
 
  CMAKE_SYSTEM_LIBRARY_PATH
      Path used for searching by FIND_LIBRARY().
 
      Specifies a path which will be used by FIND_LIBRARY().  FIND_LIBRARY()
      will check each of the contained directories for the existence of the
      library which is currently searched.  By default it contains the
      standard directories for the current system.  It is NOT intended to be
      modified by the project, use CMAKE_LIBRARY_PATH for this.  See also
      CMAKE_SYSTEM_PREFIX_PATH.
 
  CMAKE_SYSTEM_PREFIX_PATH
      Path used for searching by FIND_XXX(), with appropriate suffixes
      added.
 
      Specifies a path which will be used by the FIND_XXX() commands.  It
      contains the "base" directories, the FIND_XXX() commands append
      appropriate subdirectories to the base directories.  So FIND_PROGRAM()
      adds /bin to each of the directories in the path, FIND_LIBRARY()
      appends /lib to each of the directories, and FIND_PATH() and
      FIND_FILE() append /include .  By default this contains the standard
      directories for the current system.  It is NOT intended to be modified
      by the project, use CMAKE_PREFIX_PATH for this.  See also
      CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_SYSTEM_LIBRARY_PATH,
      CMAKE_SYSTEM_PROGRAM_PATH, and CMAKE_SYSTEM_IGNORE_PATH.
 
  CMAKE_SYSTEM_PROGRAM_PATH
      Path used for searching by FIND_PROGRAM().
 
      Specifies a path which will be used by FIND_PROGRAM().  FIND_PROGRAM()
      will check each of the contained directories for the existence of the
      program which is currently searched.  By default it contains the
      standard directories for the current system.  It is NOT intended to be
      modified by the project, use CMAKE_PROGRAM_PATH for this.  See also
      CMAKE_SYSTEM_PREFIX_PATH.
 
  CMAKE_USER_MAKE_RULES_OVERRIDE
      Specify a CMake file that overrides platform information.
 
      CMake loads the specified file while enabling support for each
      language from either the project() or enable_language() commands.  It
      is loaded after CMake's builtin compiler and platform information
      modules have been loaded but before the information is used.  The file
      may set platform information variables to override CMake's defaults.
 
      This feature is intended for use only in overriding information
      variables that must be set before CMake builds its first test project
      to check that the compiler for a language works.  It should not be
      used to load a file in cases that a normal include() will work.  Use
      it only as a last resort for behavior that cannot be achieved any
      other way.  For example, one may set CMAKE_C_FLAGS_INIT to change the
      default value used to initialize CMAKE_C_FLAGS before it is cached.
      The override file should NOT be used to set anything that could be set
      after languages are enabled, such as variables like
      CMAKE_RUNTIME_OUTPUT_DIRECTORY that affect the placement of binaries.
      Information set in the file will be used for try_compile and try_run
      builds too.
 
  CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION
      Ask cmake_install.cmake script to warn each time a file with absolute
      INSTALL DESTINATION is encountered.
 
      This variable is used by CMake-generated cmake_install.cmake scripts.
      If ones set this variable to ON while running the script, it may get
      warning messages from the script.

      Using the Visual Studio 2005 compiler from Microsoft
 
      Set to true when using the Visual Studio 2005 compiler from Microsoft.
 
  CMAKE_HOST_APPLE
      True for Apple OSXoperating systems.
 
      Set to true when the host system is Apple OSX.
 
  CMAKE_HOST_SYSTEM

      The same as CMAKE_SYSTEM_PROCESSOR but for the host system instead of
      the target system when cross compiling.
 
  CMAKE_HOST_SYSTEM_VERSION
      OS version CMake is running on.
 
      The same as CMAKE_SYSTEM_VERSION but for the host system instead of
      the target system when cross compiling.

      one of the enabled languages.
 
  CMAKE_LIBRARY_ARCHITECTURE_REGEX
      Regex matching possible target architecture library directory names.
 
      This is used to detect CMAKE_<lang>_LIBRARY_ARCHITECTURE from the
      implicit linker search path by matching the <arch> name.
 
  CMAKE_OBJECT_PATH_MAX
      Maximum object file full-path length allowed by native build tools.
 
      CMake computes for every source file an object file name that is
      unique to the source file and deterministic with respect to the full
      path to the source file.  This allows multiple source files in a
      target to share the same name if they lie in different directories
      without rebuilding when one is added or removed.  However, it can
      produce long full paths in a few cases, so CMake shortens the path
      using a hashing scheme when the full path to an object file exceeds a
      limit.  CMake has a built-in limit for each platform that is
      sufficient for common tools, but some native tools may have a lower
      limit.  This variable may be set to specify the limit explicitly.  The
      value must be an integer no less than 128.
 
  CMAKE_SYSTEM
      Name of system cmake is compiling for.
 
      This variable is the composite of CMAKE_SYSTEM_NAME and
      CMAKE_SYSTEM_VERSION, like this
      ${CMAKE_SYSTEM_NAME}-${CMAKE_SYSTEM_VERSION}.  If CMAKE_SYSTEM_VERSION
      is not set, then CMAKE_SYSTEM is the same as CMAKE_SYSTEM_NAME.
 
  CMAKE_SYSTEM_NAME
      Name of the OS CMake is building for.
 
      This is the name of the operating system on which CMake is targeting.
      On systems that have the uname command, this variable is set to the
      output of uname -s.  Linux, Windows, and Darwin for Mac OSX are the
      values found on the big three operating systems.
 
  CMAKE_SYSTEM_PROCESSOR
      The name of the CPU CMake is building for.
 
      On systems that support uname, this variable is set to the output of
      uname -p, on windows it is set to the value of the environment
      variable PROCESSOR_ARCHITECTURE
 
  CMAKE_SYSTEM_VERSION
      OS version CMake is building for.
 
      A numeric version string for the system, on systems that support
      uname, this variable is set to the output of uname -r.  On other

  MSVC90
      True when using Microsoft Visual C 9.0
 
      Set to true when the compiler is version 9.0 of Microsoft Visual C.
 
  MSVC_IDE
      True when using the Microsoft Visual C IDE
 
      Set to true when the target platform is the Microsoft Visual C IDE, as
      opposed to the command line compiler.
 
  MSVC_VERSION
      The version of Microsoft Visual C/C++ being used if any.
 
      Known version numbers are:

  CMAKE_<LANG>_ARCHIVE_APPEND
      Rule variable to append to a static archive.
 
      This is a rule variable that tells CMake how to append to a static
      archive.  It is used in place of CMAKE_<LANG>_CREATE_STATIC_LIBRARY on

  CMAKE_<LANG>_IGNORE_EXTENSIONS
      File extensions that should be ignored by the build.
 
      This is a list of file extensions that may be part of a project for a
      given language but are not compiled.
 
  CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES
      Directories implicitly searched by the compiler for header files.
 
      CMake does not explicitly specify these directories on compiler
      command lines for language <LANG>.  This prevents system include
      directories from being treated as user include directories on some
      compilers.
 
  CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES
      Implicit linker search path detected for language <LANG>.
 
      Compilers typically pass directories containing language runtime
      libraries and default library search paths when they invoke a linker.
      These paths are implicit linker search directories for the compiler's
      language.  CMake automatically detects these directories for each
      language and reports the results in this variable.
 
  CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
      Implicit link libraries and flags detected for language <LANG>.
 
      Compilers typically pass language runtime library names and other
      flags when they invoke a linker.  These flags are implicit link
      options for the compiler's language.  CMake automatically detects
      these libraries and flags for each language and reports the results in
      this variable.
 
  CMAKE_<LANG>_LIBRARY_ARCHITECTURE
      Target architecture library directory name detected for <lang>.
 
      If the <lang> compiler passes to the linker an architecture-specific
      system library search directory such as <prefix>/lib/<arch> this
      variable contains the <arch> name if/as detected by CMake.
 
  CMAKE_<LANG>_LINKER_PREFERENCE
      Preference value for linker language selection.
 
      The "linker language" for executable, shared library, and module
      targets is the language whose compiler will invoke the linker.  The
      LINKER_LANGUAGE target property sets the language explicitly.
      Otherwise, the linker language is that whose linker preference value
      is highest among languages compiled and linked into the target.  See
      also the CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES variable.
 
  CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES
      True if CMAKE_<LANG>_LINKER_PREFERENCE propagates across targets.
 
      This is used when CMake selects a linker language for a target.
      Languages compiled directly into the target are always considered.  A
      language compiled into static libraries linked by the target is
      considered if this variable is true.
 
  CMAKE_<LANG>_LINK_EXECUTABLE
      Rule variable to link and executable.
 
      Rule variable to link and executable for the given language.
 
  CMAKE_<LANG>_OUTPUT_EXTENSION
      Extension for the output of a compile for a single file.
 
      This is the extension for an object file for the given <LANG>.  For
      example .obj for C on Windows.
 
  CMAKE_<LANG>_PLATFORM_ID
      An internal variable subject to change.
 
      This is used in determining the platform and is subject to change.
 
  CMAKE_<LANG>_SIZEOF_DATA_PTR
      Size of pointer-to-data types for language <LANG>.
 
      This holds the size (in bytes) of pointer-to-data types in the target
      platform ABI.  It is defined for languages C and CXX (C++).
 
  CMAKE_<LANG>_SOURCE_FILE_EXTENSIONS
      Extensions of source files for the given language.
 
      This is the list of extensions for a given languages source files.
 
  CMAKE_COMPILER_IS_GNU<LANG>
      True if the compiler is GNU.
 
      If the selected <LANG> compiler is the GNU compiler then this is TRUE,
      if not it is FALSE.
 
  CMAKE_Fortran_MODDIR_DEFAULT
      Fortran default module output directory.
 
      Most Fortran compilers write .mod files to the current working
      directory.  For those that do not, this is set to "." and used when
      the Fortran_MODULE_DIRECTORY target property is not set.
 
  CMAKE_Fortran_MODDIR_FLAG
      Fortran flag for module output directory.
 
      This stores the flag needed to pass the value of the
      Fortran_MODULE_DIRECTORY target property to the compiler.
 
  CMAKE_Fortran_MODOUT_FLAG
      Fortran flag to enable module output.
 
      Most Fortran compilers write .mod files out by default.  For others,
      this stores the flag needed to enable module output.
 
  CMAKE_INTERNAL_PLATFORM_ABI
      An internal variable subject to change.
 
      This is used in determining the compiler ABI and is subject to change.
 
  CMAKE_USER_MAKE_RULES_OVERRIDE_<LANG>
      Specify a CMake file that overrides platform information for <LANG>.
 
      This is a language-specific version of CMAKE_USER_MAKE_RULES_OVERRIDE
      loaded only when enabling language <LANG>.
 
------------------------------------------------------------------------------
Variables that Control the Build
 
  CMAKE_<CONFIG>_POSTFIX
      Default filename postfix for libraries under configuration <CONFIG>.
 
      When a non-executable target is created its <CONFIG>_POSTFIX target
      property is initialized with the value of this variable if it is set.
 
  CMAKE_ARCHIVE_OUTPUT_DIRECTORY
      Where to put all the ARCHIVE targets when built.
 
      This variable is used to initialize the ARCHIVE_OUTPUT_DIRECTORY
      property on all the targets.  See that target property for additional
      information.
 
  CMAKE_AUTOMOC
      Whether to handle moc automatically for Qt targets.
 
      This variable is used to initialize the AUTOMOC property on all the
      targets.  See that target property for additional information.
 
  CMAKE_AUTOMOC_MOC_OPTIONS
      Additional options for moc when using automoc (see CMAKE_AUTOMOC).
 
      This variable is used to initialize the AUTOMOC_MOC_OPTIONS property
      on all the targets.  See that target property for additional
      information.
 
  CMAKE_BUILD_WITH_INSTALL_RPATH
      Use the install path for the RPATH
 
      Normally CMake uses the build tree for the RPATH when building
      executables etc on systems that use RPATH.  When the software is
      installed the executables etc are relinked by CMake to have the
      install RPATH.  If this variable is set to true then the software is
      always built with the install path for the RPATH and does not need to
      be relinked when installed.
 
  CMAKE_DEBUG_POSTFIX
      See variable CMAKE_<CONFIG>_POSTFIX.
 
      This variable is a special case of the more-general
      CMAKE_<CONFIG>_POSTFIX variable for the DEBUG configuration.
 
  CMAKE_EXE_LINKER_FLAGS
      Linker flags used to create executables.
 
      Flags used by the linker when creating an executable.
 
  CMAKE_EXE_LINKER_FLAGS_[CMAKE_BUILD_TYPE]
      Flag used when linking an executable.
 
      Same as CMAKE_C_FLAGS_* but used by the linker when creating
      executables.
 
  CMAKE_Fortran_FORMAT
      Set to FIXED or FREE to indicate the Fortran source layout.
 
      This variable is used to initialize the Fortran_FORMAT property on all
      the targets.  See that target property for additional information.
 
  CMAKE_Fortran_MODULE_DIRECTORY
      Fortran module output directory.
 
      This variable is used to initialize the Fortran_MODULE_DIRECTORY
      property on all the targets.  See that target property for additional
      information.
 
  CMAKE_GNUtoMS
      Convert GNU import libraries (.dll.a) to MS format (.lib).
 
      This variable is used to initialize the GNUtoMS property on targets
      when they are created.  See that target property for additional
      information.
 
  CMAKE_INCLUDE_CURRENT_DIR
      Automatically add the current source- and build directories to the
      include path.
 
      If this variable is enabled, CMake automatically adds in each
      directory ${CMAKE_CURRENT_SOURCE_DIR} and ${CMAKE_CURRENT_BINARY_DIR}
      to the include path for this directory.  These additional include
      directories do not propagate down to subdirectories.  This is useful
      mainly for out-of-source builds, where files generated into the build
      tree are included by files located in the source tree.
 
      By default CMAKE_INCLUDE_CURRENT_DIR is OFF.
 
  CMAKE_INSTALL_NAME_DIR
      Mac OSX directory name for installed targets.
 
      CMAKE_INSTALL_NAME_DIR is used to initialize the INSTALL_NAME_DIR
      property on all targets.  See that target property for more
      information.
 
  CMAKE_INSTALL_RPATH
      The rpath to use for installed targets.
 
      A semicolon-separated list specifying the rpath to use in installed
      targets (for platforms that support it).  This is used to initialize
      the target property INSTALL_RPATH for all targets.
 
  CMAKE_INSTALL_RPATH_USE_LINK_PATH
      Add paths to linker search and installed rpath.
 
      CMAKE_INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true
      will append directories in the linker search path and outside the
      project to the INSTALL_RPATH.  This is used to initialize the target
      property INSTALL_RPATH_USE_LINK_PATH for all targets.
 
  CMAKE_LIBRARY_OUTPUT_DIRECTORY
      Where to put all the LIBRARY targets when built.
 
      This variable is used to initialize the LIBRARY_OUTPUT_DIRECTORY
      property on all the targets.  See that target property for additional
      information.
 
  CMAKE_LIBRARY_PATH_FLAG
      The flag used to add a library search path to a compiler.
 
      The flag used to specify a library directory to the compiler.  On most
      compilers this is "-L".
 
  CMAKE_LINK_DEF_FILE_FLAG 
      Linker flag used to specify a .def file for dll creation.
 
      The flag used to add a .def file when creating a dll on Windows, this
      is only defined on Windows.
 
  CMAKE_LINK_INTERFACE_LIBRARIES
      Default value for LINK_INTERFACE_LIBRARIES of targets.
 
      This variable is used to initialize the LINK_INTERFACE_LIBRARIES
      property on all the targets.  See that target property for additional
      information.
 
  CMAKE_LINK_LIBRARY_FILE_FLAG
      Flag used to link a library specified by a path to its file.
 
      The flag used before a library file path is given to the linker.  This
      is needed only on very few platforms.
 
  CMAKE_LINK_LIBRARY_FLAG
      Flag used to link a library into an executable.
 
      The flag used to specify a library to link to an executable.  On most
      compilers this is "-l".
 
  CMAKE_MACOSX_BUNDLE
      Default value for MACOSX_BUNDLE of targets.
 
      This variable is used to initialize the MACOSX_BUNDLE property on all
      the targets.  See that target property for additional information.
 
  CMAKE_NO_BUILTIN_CHRPATH
      Do not use the builtin ELF editor to fix RPATHs on installation.
 
      When an ELF binary needs to have a different RPATH after installation
      than it does in the build tree, CMake uses a builtin editor to change
      the RPATH in the installed copy.  If this variable is set to true then
      CMake will relink the binary before installation instead of using its
      builtin editor.
 
  CMAKE_PDB_OUTPUT_DIRECTORY
      Where to put all the MS debug symbol files.
 
      This variable is used to initialize the PDB_OUTPUT_DIRECTORY property
      on all the targets.  See that target property for additional
      information.
 
  CMAKE_POSITION_INDEPENDENT_CODE
      Default value for POSITION_INDEPENDENT_CODE of targets.
 
      This variable is used to initialize the POSITION_INDEPENDENT_CODE
      property on all the targets.  See that target property for additional
      information.
 
  CMAKE_RUNTIME_OUTPUT_DIRECTORY
      Where to put all the RUNTIME targets when built.
 
      This variable is used to initialize the RUNTIME_OUTPUT_DIRECTORY
      property on all the targets.  See that target property for additional
      information.
 
  CMAKE_SKIP_BUILD_RPATH
      Do not include RPATHs in the build tree.
 
      Normally CMake uses the build tree for the RPATH when building
      executables etc on systems that use RPATH.  When the software is
      installed the executables etc are relinked by CMake to have the
      install RPATH.  If this variable is set to true then the software is
      always built with no RPATH.
 
  CMAKE_SKIP_INSTALL_RPATH
      Do not include RPATHs in the install tree.
 
      Normally CMake uses the build tree for the RPATH when building
      executables etc on systems that use RPATH.  When the software is
      installed the executables etc are relinked by CMake to have the
      install RPATH.  If this variable is set to true then the software is
      always installed without RPATH, even if RPATH is enabled when
      building.  This can be useful for example to allow running tests from
      the build directory with RPATH enabled before the installation step.
      To omit RPATH in both the build and install steps, use
      CMAKE_SKIP_RPATH instead.
 
  CMAKE_TRY_COMPILE_CONFIGURATION
      Build configuration used for try_compile and try_run projects.
 
      Projects built by try_compile and try_run are built synchronously
      during the CMake configuration step.  Therefore a specific build
      configuration must be chosen even if the generated build system
      supports multiple configurations.
 
  CMAKE_USE_RELATIVE_PATHS
      Use relative paths (May not work!).
 
      If this is set to TRUE, then the CMake will use relative paths between
      the source and binary tree.  This option does not work for more
      complicated projects, and relative paths are used when possible.  In
      general, it is not possible to move CMake generated makefiles to a
      different location regardless of the value of this variable.
 
  CMAKE_WIN32_EXECUTABLE
      Default value for WIN32_EXECUTABLE of targets.
 
      This variable is used to initialize the WIN32_EXECUTABLE property on
      all the targets.  See that target property for additional information.
 
  EXECUTABLE_OUTPUT_PATH
      Old executable location variable.
 
      The target property RUNTIME_OUTPUT_DIRECTORY supercedes this variable
      for a target if it is set.  Executable targets are otherwise placed in
      this directory.
 
  LIBRARY_OUTPUT_PATH
      Old library location variable.
 
      The target properties ARCHIVE_OUTPUT_DIRECTORY,
      LIBRARY_OUTPUT_DIRECTORY, and RUNTIME_OUTPUT_DIRECTORY supercede this
      variable for a target if they are set.  Library targets are otherwise
      placed in this directory.

      This variable is set to the program that will be needed to build the
      output of CMake.  If the generator selected was Visual Studio 6, the
      CMAKE_BUILD_TOOL will be set to msdev, for Unix makefiles it will be
      set to make or gmake, and for Visual Studio 7 it set to devenv.  For
      Nmake Makefiles the value is nmake.  This can be useful for adding
      special flags and commands based on the final build environment.
 
  CMAKE_CACHEFILE_DIR
      The directory with the CMakeCache.txt file.
 
      This is the full path to the directory that has the CMakeCache.txt
      file in it.  This is the same as CMAKE_BINARY_DIR.
 
  CMAKE_CACHE_MAJOR_VERSION
      Major version of CMake used to create the CMakeCache.txt file
 
      This is stores the major version of CMake used to write a CMake cache
      file.  It is only different when a different version of CMake is run
      on a previously created cache file.
 
  CMAKE_CACHE_MINOR_VERSION
      Minor version of CMake used to create the CMakeCache.txt file
 
      This is stores the minor version of CMake used to write a CMake cache
      file.  It is only different when a different version of CMake is run
      on a previously created cache file.
 
  CMAKE_CACHE_PATCH_VERSION
      Patch version of CMake used to create the CMakeCache.txt file
 
      This is stores the patch version of CMake used to write a CMake cache
      file.  It is only different when a different version of CMake is run
      on a previously created cache file.
 
  CMAKE_CFG_INTDIR
      Build-time reference to per-configuration output subdirectory.
 
      For native build systems supporting multiple configurations in the
      build tree (such as Visual Studio and Xcode), the value is a reference
      to a build-time variable specifying the name of the per-configuration
      output subdirectory.  On Makefile generators this evaluates to "."
      because there is only one configuration in a build tree.  Example
      values:
 
        $(IntDir)        = Visual Studio 6
        $(OutDir)        = Visual Studio 7, 8, 9
        $(Configuration) = Visual Studio 10
        $(CONFIGURATION) = Xcode
        .                = Make-based tools
 
      Since these values are evaluated by the native build system, this
      variable is suitable only for use in command lines that will be
      evaluated at build time.  Example of intended usage:
 
        add_executable(mytool mytool.c)
        add_custom_command(
          OUTPUT out.txt
          COMMAND ${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool
                  ${CMAKE_CURRENT_SOURCE_DIR}/in.txt out.txt
          DEPENDS mytool in.txt
          )
        add_custom_target(drive ALL DEPENDS out.txt)
 
      Note that CMAKE_CFG_INTDIR is no longer necessary for this purpose but
      has been left for compatibility with existing projects.  Instead
      add_custom_command() recognizes executable target names in its COMMAND
      option, so "${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool"
      can be replaced by just "mytool".
 
      This variable is read-only.  Setting it is undefined behavior.  In
      multi-configuration build systems the value of this variable is passed
      as the value of preprocessor symbol "CMAKE_INTDIR" to the compilation
      of all source files.
 
  CMAKE_COMMAND
      The full path to the cmake executable.
 
      This is the full path to the CMake executable cmake which is useful
      from custom commands that want to use the cmake -E option for portable
      system commands.  (e.g.  /usr/local/bin/cmake
 
  CMAKE_CROSSCOMPILING
      Is CMake currently cross compiling.
 
      This variable will be set to true by CMake if CMake is cross
      compiling.  Specifically if the build platform is different from the
      target platform.
 
  CMAKE_CTEST_COMMAND
      Full path to ctest command installed with cmake.
 
      This is the full path to the CTest executable ctest which is useful
      from custom commands that want to use the cmake -E option for portable
      system commands.
 
  CMAKE_CURRENT_BINARY_DIR
      The path to the binary directory currently being processed.
 
      This the full path to the build directory that is currently being
      processed by cmake.  Each directory added by add_subdirectory will
      create a binary directory in the build tree, and as it is being
      processed this variable will be set.  For in-source builds this is the
      current source directory being processed.
 
  CMAKE_CURRENT_LIST_DIR
      Full directory of the listfile currently being processed.
 
      As CMake processes the listfiles in your project this variable will
      always be set to the directory where the listfile which is currently
      being processed (CMAKE_CURRENT_LIST_FILE) is located.  The value has
      dynamic scope.  When CMake starts processing commands in a source file
      it sets this variable to the directory where this file is located.
      When CMake finishes processing commands from the file it restores the
      previous value.  Therefore the value of the variable inside a macro or
      function is the directory of the file invoking the bottom-most entry
      on the call stack, not the directory of the file containing the macro
      or function definition.
 
      See also CMAKE_CURRENT_LIST_FILE.
 
  CMAKE_CURRENT_LIST_FILE
      Full path to the listfile currently being processed.
 
      As CMake processes the listfiles in your project this variable will
      always be set to the one currently being processed.  The value has
      dynamic scope.  When CMake starts processing commands in a source file
      it sets this variable to the location of the file.  When CMake
      finishes processing commands from the file it restores the previous
      value.  Therefore the value of the variable inside a macro or function
      is the file invoking the bottom-most entry on the call stack, not the
      file containing the macro or function definition.
 
      See also CMAKE_PARENT_LIST_FILE.
 
  CMAKE_CURRENT_LIST_LINE
      The line number of the current file being processed.
 
      This is the line number of the file currently being processed by
      cmake.
 
  CMAKE_CURRENT_SOURCE_DIR
      The path to the source directory currently being processed.
 
      This the full path to the source directory that is currently being
      processed by cmake.

  CMAKE_EXTRA_GENERATOR
      The extra generator used to build the project.
 
      When using the Eclipse, CodeBlocks or KDevelop generators, CMake
      generates Makefiles (CMAKE_GENERATOR) and additionally project files
      for the respective IDE.  This IDE project file generator is stored in
      CMAKE_EXTRA_GENERATOR (e.g.  "Eclipse CDT4").
 
  CMAKE_EXTRA_SHARED_LIBRARY_SUFFIXES
      Additional suffixes for shared libraries.
 
      Extensions for shared libraries other than that specified by
      CMAKE_SHARED_LIBRARY_SUFFIX, if any.  CMake uses this to recognize
      external shared library files during analysis of libraries linked by a
      target.
 
  CMAKE_GENERATOR
      The generator used to build the project.
 
      The name of the generator that is being used to generate the build

      This specifies the minor version of the CMake executable being run.
 
  CMAKE_PARENT_LIST_FILE
      Full path to the parent listfile of the one currently being processed.
 
      As CMake processes the listfiles in your project this variable will
      always be set to the listfile that included or somehow invoked the one
      currently being processed.  See also CMAKE_CURRENT_LIST_FILE.
 
  CMAKE_PATCH_VERSION
      The patch version of cmake (i.e.  the 3 in X.X.3).

      directory can be found here.  This is commonly used in this format:
      ${CMAKE_ROOT}/Modules
 
  CMAKE_SCRIPT_MODE_FILE
      Full path to the -P script file currently being processed.
 
      When run in -P script mode, CMake sets this variable to the full path

      variable is not set.
 
  CMAKE_SHARED_LIBRARY_PREFIX
      The prefix for shared libraries that you link to.

      Size of a void pointer.
 
      This is set to the size of a pointer on the machine, and is determined
      by a try compile.  If a 64 bit size is found, then the library search
      path is modified to look for 64 bit libraries first.
 
  CMAKE_SKIP_RPATH
      If true, do not add run time path information.
 
      If this is set to TRUE, then the rpath information is not added to
      compiled executables.  The default is to add rpath information if the
      platform supports it.  This allows for easy running from the build
      tree.  To omit RPATH in the install step, but not the build step, use
      CMAKE_SKIP_INSTALL_RPATH instead.
 
  CMAKE_SOURCE_DIR
      The path to the top level of the source tree.
 
      This is the full path to the top level of the current CMake source
      tree.  For an in-source build, this would be the same as

      This specifies the tweak version of the CMake executable being run.
      Releases use tweak < 20000000 and development versions use the date
      format CCYYMMDD for the tweak level.
 
  CMAKE_VERBOSE_MAKEFILE
      Create verbose makefiles if on.
 
      This variable defaults to false.  You can set this variable to true to
      make CMake produce verbose makefiles that show each command line as it
      is used.
 
  CMAKE_VERSION
      The full version of cmake in major.minor.patch[.tweak[-id]] format.
 
      This specifies the full version of the CMake executable being run.
      This variable is defined by versions 2.6.3 and higher.  See variables
      CMAKE_MAJOR_VERSION, CMAKE_MINOR_VERSION, CMAKE_PATCH_VERSION, and
      CMAKE_TWEAK_VERSION for individual version components.  The [-id]
      component appears in non-release versions and may be arbitrary text.
 
  CMAKE_VS_PLATFORM_TOOLSET
      Visual Studio Platform Toolset name.

      This is the source directory of the most recent PROJECT command.
 
  [Project name]_BINARY_DIR
      Top level binary directory for the named project.
 
      A variable is created with the name used in the PROJECT command, and
      is the binary directory for the project.  This can be useful when
      SUBDIR is used to connect several projects.
 
  [Project name]_SOURCE_DIR
      Top level source directory for the named project.
 
      A variable is created with the name used in the PROJECT command, and
