cmake version 2.4-patch 7
------------------------------------------------------------------------------
Name
 
  cmake - Cross-Platform Makefile Generator.
 
------------------------------------------------------------------------------
Usage
 
  cmake [options] <path-to-source>
  cmake [options] <path-to-existing-build>
 
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.
 
------------------------------------------------------------------------------
Command-Line 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.
 
  -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.
 
  -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.
 
  -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.
 
  -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.
 
  --graphviz=[file]
      Generate graphviz of dependencies.
 
      Generate a graphviz input file that will contain all the library and
      executable dependencies in the project.
 
  --debug-trycompile
      Do not delete the try compile directories..
 
      Do not delete the files and directories created for try_compile calls.
      This is useful in debugging failed try_compiles.
 
  --debug-output
      Put cmake in a debug mode.
 
      Print extra stuff during the cmake run like stack traces with
      message(send_error ) calls.
 
  --help-command cmd [file]
      Print help for a single command and exit.
 
      Full documentation specific to the given command is displayed.
 
  --help-command-list [file]
      List available listfile commands and exit.
 
      The list contains all commands for which help may be obtained by using
      the --help-command argument followed by a command name.  If a file is
      specified, the help is written into it.
 
  --help-module module [file]
      Print help for a single module and exit.
 
      Full documentation specific to the given module is displayed.
 
  --help-module-list [file]
      List available modules and exit.
 
      The list contains all modules for which help may be obtained by using
      the --help-module argument followed by a module name.  If a file is
      specified, the help is written into it.
 
  --copyright [file]
      Print the CMake copyright and exit.
 
      If a file is specified, the copyright is written into it.
 
  --help
      Print usage information and exit.
 
      Usage describes the basic command line interface and its options.
 
  --help-full [file]
      Print full help and exit.
 
      Full help displays most of the documentation provided by the UNIX man
      page.  It is provided for use on non-UNIX platforms, but is also
      convenient if the man page is not installed.  If a file is specified,
      the help is written into it.
 
  --help-html [file]
      Print full help in HTML format.
 
      This option is used by CMake authors to help produce web pages.  If a
      file is specified, the help is written into it.
 
  --help-man [file]
      Print a UNIX man page and exit.
 
      This option is used by the cmake build to generate the UNIX man page.
      If a file is specified, the help is written into it.
 
  --version [file]
      Show program name/version banner and exit.
 
      If a file is specified, the version is written into it.
 
------------------------------------------------------------------------------
Generators
 
The following generators are available on this platform:
 
  KDevelop3
      Generates KDevelop 3 project files.
 
      Project files for KDevelop 3 will be created in the top directory and
      in every subdirectory which features a CMakeLists.txt file containing
      a PROJECT() call.  If you change the settings using KDevelop cmake
      will try its best to keep your changes when regenerating the project
      files.  Additionally 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.
 
  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.
 
------------------------------------------------------------------------------
Listfile Commands
 
The following commands are available in CMakeLists.txt code:
 
  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...]]
                            [WORKING_DIRECTORY dir]
                            [COMMENT comment] [VERBATIM] [APPEND])
 
      This defines a new command that can be executed during the build
      process.  The outputs named should be listed as source files in the
      target for which they are to be generated.  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:
 
        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 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 the arguments to the commands will be
      passed exactly as specified no matter the build tool used.  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.  In the future VERBATIM may
      be enabled by default.  The only reason it is an option is to preserve
      compatibility with older CMake code.
 
      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.
 
  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])
 
      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 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.
 
      If VERBATIM is given then all the arguments to the commands will be
      passed exactly as specified no matter the build tool used.  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.  In the future VERBATIM may
      be enabled by default.  The only reason it is an option is to preserve
      compatibility with older CMake code.
 
  ADD_DEFINITIONS
      Adds -D define flags to the command line of C and C++ compilers.
 
        ADD_DEFINITIONS(-DFOO -DBAR ...)
 
      Adds flags to command line of C and C++ compilers.  This command can
      be used to add any flag to a compile line, but the -D flag is accepted
      most C/C++ compilers.  Other flags may not be as portable.
 
  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.  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(exename [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL]
                        source1 source2 ... sourceN)
 
      This command adds an executable target to the current directory.  The
      executable will be built from the list of source files specified.
 
      After specifying the executable name, WIN32 and/or MACOSX_BUNDLE can
      be specified.  WIN32 indicates that the executable (when compiled on
      windows) is a windows app (using WinMain) not a console app (using
      main).  The variable CMAKE_MFC_FLAG be used if the windows app uses
      MFC.  This variable can be set to the following values:
 
        0: Use Standard Windows Libraries
        1: Use MFC in a Static Library
        2: Use MFC in a Shared DLL
 
      MACOSX_BUNDLE indicates that when build on Mac OSX, executable should
      be in the bundle form.  The MACOSX_BUNDLE also allows several
      variables to be specified:
 
        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
 
      If EXCLUDE_FROM_ALL is given the target will not be built by default.
      It will be built only if the user explicitly builds the target or
      another target that requires the target depends on it.
 
  ADD_LIBRARY
      Add a library to the project using the specified source files.
 
        ADD_LIBRARY(libname [SHARED | STATIC | MODULE] [EXCLUDE_FROM_ALL]
                    source1 source2 ... sourceN)
 
      Adds a library target.  SHARED, STATIC or MODULE keywords are used to
      set the library type.  If the keyword MODULE appears, the library type
      is set to MH_BUNDLE on systems which use dyld.  On systems without
      dyld, MODULE is treated like SHARED.  If no keywords appear as the
      second argument, the type defaults to the current value of
      BUILD_SHARED_LIBS.  If this variable is not set, the type defaults to
      STATIC.
 
      If EXCLUDE_FROM_ALL is given the target will not be built by default.
      It will be built only if the user explicitly builds the target or
      another target that requires the target depends on it.
 
  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 this subdirectory
      will not be included in build by default.  Users will have to
      explicitly start a build in the generated output directory.  This is
      useful for having cmake create a build system for a set of examples in
      a project.  One would want cmake to generate a single build system for
      all the examples, but one may not want the targets to show up in the
      main build system.
 
  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.
 
  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.
 
  BUILD_COMMAND
      Get the command line that will build this project.
 
        BUILD_COMMAND(variable MAKECOMMAND)
 
      Sets the given variable to a string containing the command that will
      build this project from the root of the build tree using the build
      tool given by MAKECOMMAND.  MAKECOMMAND should be msdev, nmake, make
      or one of the end user build tools.  This is useful for configuring
      testing systems.
 
  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.
 
  CMAKE_MINIMUM_REQUIRED
      Set the minimum required version of cmake for a project.
 
        CMAKE_MINIMUM_REQUIRED(VERSION versionNumber [FATAL_ERROR])
 
      Let cmake know that the project requires a certain version of a cmake,
      or newer.  CMake will also try to be backwards compatible to the
      version of cmake specified, if a newer version of cmake is running.
      If FATAL_ERROR is given then failure to meet the requirements will be
      considered an error instead of a warning.
 
  CONFIGURE_FILE
      Copy a file to another location and modify its contents.
 
        CONFIGURE_FILE(InputFile OutputFile
                        [COPYONLY] [ESCAPE_QUOTES] [@ONLY])
 
      The Input and Ouput files have to have full paths.  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
 
  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();) 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.
 
  ELSE
      Starts the ELSE portion of an IF block.
 
        ELSE(expression)
 
      See the IF command.
 
  ELSEIF
      Starts the ELSEIF portion of an IF block.
 
        ELSEIF(expression)
 
      See the IF command.
 
  ENABLE_LANGUAGE
      Set a name for the entire project.
 
        ENABLE_LANGUAGE(languageName)
 
      This command enables support for the named language in CMake.
 
  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.
 
  ENDFOREACH
      Ends a list of commands in a FOREACH block.
 
        ENDFOREACH(expression)
 
      See the FOREACH command.
 
  ENDIF
      Ends a list of commands in an IF block.
 
        ENDIF(expression)
 
      See the IF command.
 
  ENDMACRO
      Ends a list of commands in a MACRO block.
 
        ENDMACRO(expression)
 
      See the MACRO command.
 
  ENDWHILE
      Ends a list of commands in a WHILE block.
 
        ENDWHILE(expression)
 
      See the WHILE command.
 
  EXEC_PROGRAM
      Run and 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.
 
      The EXECUTE_PROCESS command is a newer more powerful version of
      EXEC_PROGRAM, but the old command has been kept for compatibility.
 
  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_LIBRARY_DEPENDENCIES
      Write out the dependency information for all targets of a project.
 
        EXPORT_LIBRARY_DEPENDENCIES(FILE [APPEND])
 
      Create a 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.
 
  FILE
      File manipulation command.
 
        FILE(WRITE filename "message to write"... )
        FILE(APPEND filename "message to write"... )
        FILE(READ filename variable)
        FILE(GLOB variable [RELATIVE path] [globbing expressions]...)
        FILE(GLOB_RECURSE variable [RELATIVE path]
              [globbing expressions]...)
        FILE(REMOVE [directory]...)
        FILE(REMOVE_RECURSE [directory]...)
        FILE(MAKE_DIRECTORY [directory]...)
        FILE(RELATIVE_PATH variable directory file)
        FILE(TO_CMAKE_PATH path result)
        FILE(TO_NATIVE_PATH path result)
 
      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
 
      NOTE: When using FILE WRITE and FILE APPEND, 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.
 
      READ will read the content of a file and store it into the variable.
 
      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.
 
      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 similar list as the regular GLOB, except it
      will traverse all the subdirectories of the matched directory and
      match the files.
 
      Examples of recursive globbing include:
 
          /dir/*.py  - match all python files in /dir and subdirectories
 
      MAKE_DIRECTORY will create a directory at the specified location
 
      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.
 
      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.
 
  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 path2 path2
      ...)
 
          FIND_FILE(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    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]
                  )
 
      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 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 can be used
      to give sub directories that will be appended to the search paths.
 
      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 cmake specific environment variables.  This can be skipped
      if NO_CMAKE_ENVIRONMENT_PATH is passed.
 
          CMAKE_FRAMEWORK_PATH
          CMAKE_APPBUNDLE_PATH
          CMAKE_INCLUDE_PATH
 
      2.  Search cmake variables with the same names as the cmake specific
      environment 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_FRAMEWORK_PATH
          CMAKE_APPBUNDLE_PATH
          CMAKE_INCLUDE_PATH
 
      3.  Search the standard system environment variables.  This can be
      skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.
 
          PATH
          INCLUDE
 
      4.  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_FRAMEWORK_PATH
          CMAKE_SYSTEM_APPBUNDLE_PATH
          CMAKE_SYSTEM_INCLUDE_PATH
 
      5.  Search the paths specified after PATHS or in the short-hand
      version of the command.
 
      On Darwin or systems supporting OSX 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 OSX 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 reason the paths listed in the call to the command are searched
      last is that most users of CMake would expect things to be found first
      in the locations specified by their environment.  Projects may
      override this behavior by simply calling the command twice:
 
          FIND_FILE(<VAR> NAMES name PATHS paths NO_DEFAULT_PATH)
          FIND_FILE(<VAR> NAMES name)
 
      Once one of these calls succeeds the result variable will be set and
      stored in the cache so that neither 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 path2
      path2 ...)
 
          FIND_LIBRARY(
                    <VAR>
                    name | NAMES name1 [name2 ...]

                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_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 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 can be used to give sub directories that will be
      appended to the search paths.
 
      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 cmake specific environment variables.  This can be skipped
      if NO_CMAKE_ENVIRONMENT_PATH is passed.
 
          CMAKE_FRAMEWORK_PATH
          CMAKE_APPBUNDLE_PATH
          CMAKE_LIBRARY_PATH
 
      2.  Search cmake variables with the same names as the cmake specific
      environment 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_FRAMEWORK_PATH
          CMAKE_APPBUNDLE_PATH
          CMAKE_LIBRARY_PATH
 
      3.  Search the standard system environment variables.  This can be
      skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.
 
          PATH
          LIB
 
      4.  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_FRAMEWORK_PATH
          CMAKE_SYSTEM_APPBUNDLE_PATH
          CMAKE_SYSTEM_LIBRARY_PATH
 
      5.  Search the paths specified after PATHS or in the short-hand

          FIND_LIBRARY(<VAR> NAMES name)
 
      Once one of these calls succeeds the result variable will be set and
      stored in the cache so that neither 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.
 
  FIND_PACKAGE
      Load settings for an external project.
 
        FIND_PACKAGE(<name> [major.minor] [QUIET] [NO_MODULE]
                      [[REQUIRED|COMPONENTS] [componets...]])
 
      Finds and loads settings from an external project.  <name>_FOUND will
      be set to indicate whether the package was found.  Settings that can
      be used when <name>_FOUND is true are package-specific.  The package
      is found through several steps.  Directories listed in
      CMAKE_MODULE_PATH are searched for files called "Find<name>.cmake".
      If such a file is found, it is read and processed by CMake, and is
      responsible for finding the package.  This first step may be skipped
      by using the NO_MODULE option.  If no such file is found, it is
      expected that the package is another project built by CMake that has a
      "<name>Config.cmake" file.  A cache entry called <name>_DIR is created
      and is expected to be set to the directory containing this file.  If
      the file is found, it is read and processed by CMake to load the
      settings of the package.  If <name>_DIR has not been set during a
      configure step, the command will generate an error describing the
      problem unless the QUIET argument is specified.  If <name>_DIR has
      been set to a directory not containing a "<name>Config.cmake" file, an
      error is always generated.  If REQUIRED is specified and the package
      is not found, a FATAL_ERROR is generated and the configure step stops
      executing.  A package-specific list of components may be listed after
      the REQUIRED option, or after the COMPONENTS option if no REQUIRED
      option is given.
 
  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 path2 path2
      ...)
 
          FIND_PATH(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    PATHS path1 [path2 ... ENV var]

                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_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 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.

      Once one of these calls succeeds the result variable will be set and
      stored in the cache so that neither 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

      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

        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)
        FOREACH(loop_var RANGE total)
        FOREACH(loop_var RANGE start stop [step])
 
      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 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.
 
  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, CMake will
      report an error.  Some supported properties include: VARIABLES,
      CACHE_VARIABLES, COMMANDS, and MACROS.
 
  GET_DIRECTORY_PROPERTY
      Get a property of the directory.
 
        GET_DIRECTORY_PROPERTY(VAR [DIRECTORY dir] property)
 
      Get a property from the Directory.  The value of the property is
      stored in the variable VAR.  If the property is not found, CMake will
      report an error.  The properties include: VARIABLES, CACHE_VARIABLES,
      COMMANDS, MACROS, INCLUDE_DIRECTORIES, LINK_DIRECTORIES, DEFINITIONS,
      INCLUDE_REGULAR_EXPRESSION, LISTFILE_STACK, PARENT_DIRECTORY, and
      DEFINITION varname.  If the DIRECTORY argument is provided then the
      property of the provided directory will be retrieved instead of the
      current directory.  You can only get properties of a directory during
      or after it has been traversed by cmake.
 
  GET_FILENAME_COMPONENT
      Get a specific component of a full filename.
 
        GET_FILENAME_COMPONENT(VarName FileName
                                PATH|ABSOLUTE|NAME|EXT|NAME_WE
                                [CACHE])
 
      Set VarName to be the path (PATH), file name (NAME), file extension
      (EXT), file name without extension (NAME_WE) of FileName, or the full
      absolute (ABSOLUTE) file name without symlinks.  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(VarName FileName
                                PROGRAM [PROGRAM_ARGS ArgVar]
                                [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 ArgVar.  This is used to separate
      a program name from its arguments in a command line string.
 
  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
 
  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.
 
      The read-only property "<CONFIG>_LOCATION" provides the full path to
      the file on disk that will be created for the target when building
      under configuration <CONFIG> (in upper-case, such as
      "DEBUG_LOCATION").  The read-only property "LOCATION" specifies the
      full path to the file on disk that will be created for the target.
      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).  This is very useful for executable
      targets to get the path to the executable file for use in a custom
      command.
 
      The read-only property "TYPE" returns which type the specified target
      has (EXECUTABLE, STATIC_LIBRARY, SHARED_LIBRARY, MODULE_LIBRARY,
      UTILITY, INSTALL_FILES or INSTALL_PROGRAMS).  This command can get
      properties for any target so far created.  The targets do not need to
      be in the current CMakeLists.txt file.
 
  GET_TEST_PROPERTY
      Get a property of the test.
 
        GET_TEST_PROPERTY(test VAR property)
 
      Get a property from the Test.  The value of the property is stored in
      the variable VAR.  If the property is not found, CMake will report an
      error.
 
  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 same expression must
      be given to IF, and ENDIF.  Long expressions can be used and the order
      or precedence is that the EXISTS, COMMAND, and DEFINED operators will
      be evaluated first.  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(variable)
 
      True if the variable's value is not empty, 0, N, NO, OFF, FALSE,
      NOTFOUND, or <variable>-NOTFOUND.
 
        IF(NOT variable)
 
      True if the variable's value is empty, 0, N, NO, OFF, FALSE, NOTFOUND,
      or <variable>-NOTFOUND.
 
        IF(variable1 AND variable2)
 
      True if both variables would be considered true individually.
 
        IF(variable1 OR variable2)
 
      True if either variable would be considered true individually.
 
        IF(COMMAND command-name)
 
      True if the given name is a command that can be invoked.
 
        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(IS_DIRECTORY directory-name)
 
      True if the given name is a directory.  Behavior is well-defined only
      for full paths.
 
        IF(variable MATCHES regex)
        IF(string MATCHES regex)
 
      True if the given string or variable's value matches the given regular
      expression.
 
        IF(variable LESS number)
        IF(string LESS number)
        IF(variable GREATER number)
        IF(string GREATER number)
        IF(variable EQUAL number)
        IF(string EQUAL number)
 
      True if the given string or variable's value is a valid number and the
      inequality or equality is true.
 
        IF(variable STRLESS string)
        IF(string STRLESS string)
        IF(variable STRGREATER string)
        IF(string STRGREATER string)
        IF(variable STREQUAL string)
        IF(string STREQUAL string)
 
      True if the given string or variable's value is lexicographically less
      (or greater, or equal) than the string on the right.
 
        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.
 
  INCLUDE
      Read CMake listfile code from the given file.
 
        INCLUDE(file1 [OPTIONAL])
        INCLUDE(module [OPTIONAL])
 
      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 a module is specified instead of a file, the file with name
      <modulename>.cmake is searched in the CMAKE_MODULE_PATH.
 
  INCLUDE_DIRECTORIES
      Add include directories to the build.
 
        INCLUDE_DIRECTORIES([AFTER|BEFORE] [SYSTEM] dir1 dir2 ...)
 
      Add the given directories to those searched by the compiler for
      include files.  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 BEFORE or
      AFTER you can select between appending and prepending, independent
      from the default.  If the SYSTEM option is given the compiler will be
      told that 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
                                    dep1 dep2 ...)
 
      Includes an external Microsoft project in the generated workspace
      file.  Currently does nothing on UNIX.
 
  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.  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.  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...
                [[ARCHIVE|LIBRARY|RUNTIME]
                                    [DESTINATION <dir>]
                                    [PERMISSIONS permissions...]
                                    [CONFIGURATIONS [Debug|Release|...]]
                                    [COMPONENT <component>]
                                    [OPTIONAL]
                                    ] [...])
 
      The TARGETS form specifies rules for installing targets from a
      project.  There are three kinds of target files that may be installed:
      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.  The ARCHIVE, LIBRARY, and RUNTIME 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).
 
      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.  On non-DLL platforms mySharedLib will be installed
      to <prefix>/lib and /some/full/path.
 
      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]
                [CONFIGURATIONS [Debug|Release|...]]
                [COMPONENT <component>]
                [[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.  The PATTERN and REGEX options specify a
      globbing pattern or regular expression to match directories or files
      encountered during traversal of an input directory.  The full path to
      an 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.  Options following one of these matching expressions
      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.
 
      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.
 
 
  INSTALL_FILES
      Old installation command.  Use the INSTALL command.
 
      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
      Old installation command.  Use the INSTALL command.
 
      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
      Old installation command.  Use the INSTALL command.
 
      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_DIRECTORIES
      Specify directories in which to search for libraries.
 
        LINK_DIRECTORIES(directory1 directory2 ...)
 
      Specify the paths in which the linker should search for libraries.
 
  LINK_LIBRARIES
      Link libraries to all targets added later.
 
        LINK_LIBRARIES(library1 <debug | optimized> library2 ...)
 
      This is an old CMake command for linking libraries.  Use
      TARGET_LINK_LIBRARIES unless you have a good reason for every target
      to link to the same set of libraries.
 
      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.
 
  LIST
      List operations.
 
        LIST(LENGTH <list> <output variable>)
        LIST(GET <list> <element index> [<element index> ...] <output variable>)
        LIST(APPEND <list> <element> [<element> ...])
        LIST(INSERT <list> <element_index> <element> [<element> ...])
        LIST(REMOVE_ITEM <list> <value> [<value> ...])
        LIST(REMOVE_AT <list> <index> [<index> ...])
        LIST(SORT <list>)
        LIST(REVERSE <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.
 
      INSERT will insert elements to the list to the specified location.
 
      When specifying an index, negative value corresponds to index from the
      end of the list.
 
      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.
 
 
  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 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 macros with optional arguments.  Additionally
      ARGV holds the list of all arguments given to the macro and ARGN holds
      the list of argument pass the last expected argument.
 
  MAKE_DIRECTORY
      Old directory creation command.  Use the FILE command.
 
      This command has been superceded by the FILE(MAKE_DIRECTORY ...)
      command.  It is provided for compatibility with older CMake code.
 
        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.
 
  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.
 
  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 )'.
 
  MESSAGE
      Display a message to the user.
 
        MESSAGE([SEND_ERROR | STATUS | FATAL_ERROR]
                "message to display" ...)
 
      By default the message is displayed in a pop up window (CMakeSetup),
      or in the stdout of cmake, or the error section of ccmake.  If the
      first argument is SEND_ERROR then an error is raised, and the generate
      phase will be skipped.  If the first argument is FATAL_ERROR, all
      processing is halted.  If the first argument is STATUS then the
      message is displayed in the progress line for the GUI, or with a -- in
      the command line cmake.
 
  OPTION
      Provides an option that the user can optionally select.
 
        OPTION(OPTION_VAR "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.
 
  OUTPUT_REQUIRED_FILES
      Output a list of required source files for a specified source file.
 
        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.
 
  PROJECT
      Set a name for the entire project.
 
        PROJECT(projectname [CXX] [C] [Java])
 
      Sets the name of the project.  This creates the variables
      projectname_BINARY_DIR and projectname_SOURCE_DIR.  Optionally you can
      specify which languages your project supports.  By default all
      languages are supported.  If you do not have a C++ compiler, but want
      to build a c program with cmake, then use this option.
 
  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
      Old list item removal command.  Use the LIST command.
 
      This command has been superceded by the LIST(REMOVE ...) command.  It
      is provided for compatibility with older CMake code.
 
        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.
 
  REMOVE_DEFINITIONS
      Removes -D define flags to the command line of C and C++ compilers.
 
        REMOVE_DEFINITIONS(-DFOO -DBAR ...)
 
      Removes flags from command line of C and C++ compilers.  This command
      can be used to remove any flag from a compile line, but the -D flag is
      accepted most C/C++ compilers.  Other flags may not be as portable.
 
  SEPARATE_ARGUMENTS
      Split space separated arguments into a semi-colon separated list.
 
        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 variable to a given value.
 
        SET(VAR [VALUE] [CACHE TYPE DOCSTRING [FORCE]])
 
      Within CMake sets VAR to the value VALUE.  VALUE is expanded before
      VAR is set to it.  If CACHE is present, then the VAR is put in the
      cache.  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, then the VALUE is always written into the cache,
      replacing any values existing in the cache.  If it is not a cache
      variable, then this always writes into the current makefile.  The
      FORCE option will overwrite the cache value removing any changes by
      the user.
 
        SET(VAR VALUE1 ... VALUEN).
 
      In this case VAR is set to a semicolon separated list of values.
 
      VAR can be an environment variable such as:
 
        SET( ENV{PATH} /home/martink )
 
      in which case the environment variable will be set.
 
  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_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 on a file.  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 make up your own properties as well.  The following
      are used by CMake.  The ABSTRACT flag (boolean) is used by some class
      wrapping commands.  If WRAP_EXCLUDE (boolean) is true then many
      wrapping commands will ignore this file.  If GENERATED (boolean) is
      true then it is not an error if this source file does not exist when
      it is added to a target.  Obviously, it must be created (presumably by
      a custom command) before the target is built.  If the HEADER_FILE_ONLY
      (boolean) property is true then dependency information is not created
      for that file (this is set automatically, based on the file's name's
      extension and is probably only used by Makefiles).  OBJECT_DEPENDS
      (string) adds dependencies to the object file.  COMPILE_FLAGS (string)
      is passed to the compiler as additional command line arguments when
      the source file is compiled.  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.
 
  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 our 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.
 
      When a library is built CMake by default generates code to remove any
      existing library using all possible names.  This is needed to support
      libraries that switch between STATIC and SHARED by a user option.
      However when using OUTPUT_NAME to build a static and shared library of
      the same name using different logical target names the two targets
      will remove each other's files.  This can be prevented by setting the
      CLEAN_DIRECT_OUTPUT property to 1.
 
      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.
 
 
  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_expression>
                <replace_expression> <output variable>
                <input> [<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>)
 
      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 match the given expression 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.
 
      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.
 
  SUBDIR_DEPENDS
      Legacy command.  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
      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.
 
  TARGET_LINK_LIBRARIES
      Link a target to given libraries.
 
        TARGET_LINK_LIBRARIES(target library1
                              <debug | optimized> library2
                              ...)
 
      Specify a list of libraries to be linked into the specified target.
      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
 
  TRY_COMPILE
      Try compiling some code.
 
        TRY_COMPILE(RESULT_VAR bindir srcdir
                    projectName <targetname> <CMAKE_FLAGS <Flags>>
                    <OUTPUT_VARIABLE var>)
 
      Try compiling a program.  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.
      If <target name> is specified then build just that target otherwise
      the all or ALL_BUILD target is built.
 
        TRY_COMPILE(RESULT_VAR bindir srcfile
                    <CMAKE_FLAGS <Flags>>
                    <COMPILE_DEFINITIONS <flags> ...>
                    <OUTPUT_VARIABLE var>)
 
      Try compiling a srcfile.  In this case, the user need only supply a
      source file.  CMake will create the appropriate CMakeLists.txt file to
      build the source.  In this version all files in
      bindir/CMakeFiles/CMakeTmp, will be cleaned automatically, for
      debugging a --debug-trycompile can be passed to cmake to avoid the
      clean.  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.
      Return the success or failure in RESULT_VAR.  CMAKE_FLAGS can be used
      to pass -DVAR:TYPE=VALUE flags to the cmake that is run during the
      build.
 
  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>>
                <OUTPUT_VARIABLE var>
                <ARGS <arg1> <arg2>...>)
 
      Try compiling a srcfile.  Return the success or failure in
      COMPILE_RESULT_VAR.  Then if the compile succeeded, run the executable
      and return the result in RUN_RESULT_VAR.  If the executable was built,
      but failed for to run for some reason, then RUN_RESULT_VAR will be set
      to FAILED_TO_RUN, and the output will be in the COMPILE_RESULT_VAR.
      OUTPUT_VARIABLE specifies the name of the variable to put all of the
      standard output and standard error into.
 
  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.
 
  VARIABLE_REQUIRES
      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.
 
  VTK_MAKE_INSTANTIATOR
      Deprecated.  For use only in VTK 4.0.
 
        VTK_MAKE_INSTANTIATOR(className outSourceList
                              src-list1 [src-list2 ..]
                              EXPORT_MACRO exportMacro
                              [HEADER_LOCATION dir]
                              [GROUP_SIZE groupSize]
                              [INCLUDES [file1 file2 ..]])
 
      Generates a new class with the given name and adds its files to the
      given outSourceList.  It registers the classes from the other given
      source lists with vtkInstantiator when it is loaded.  The output
      source list should be added to the library with the classes it
      registers.  The EXPORT_MACRO argument must be given and followed by
      the export macro to use when generating the class (ex.
      VTK_COMMON_EXPORT).  The HEADER_LOCATION option must be followed by a
      path.  It specifies the directory in which to place the generated
      class's header file.  The generated class implementation files always
      go in the build directory corresponding to the CMakeLists.txt file
      containing the command.  This is the default location for the header.
      The INCLUDES option can be followed by a list of zero or more files.
      These files will be #included by the generated instantiator header,
      and can be used to gain access to the specified exportMacro in the C++
      code.
 
  VTK_WRAP_JAVA
      Deprecated.  For use only in VTK 4.0.
 
        VTK_WRAP_JAVA(resultingLibraryName SourceListName
                      class1 class2 ...)
 
      Create Java wrappers for VTK classes.
 
  VTK_WRAP_PYTHON

                        class1 class2 ...)
 
      Create Python wrappers for VTK classes.
 
  VTK_WRAP_TCL
      Deprecated.  For use only in VTK 4.0.
 
        VTK_WRAP_TCL(resultingLibraryName [SOURCES]
                      SourceListName class1 class2 ...
                      [COMMANDS CommandName1 CommandName2 ...])
 
      Create Tcl wrappers for VTK classes.
 
  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 evaulated using the same logic as the IF command.
 
  WRITE_FILE
      Write a message to a file.
 
        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).
 
  AddFileDependencies
      ADD_FILE_DEPENDENCIES(source_file depend_files...)
 
      Adds the given files as dependencies to source_file
 
 
  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.
 
  CMakeExportBuildSettings
      export build settings from a project.
 
        CMAKE_EXPORT_BUILD_SETTINGS(SETTINGS_FILE)

  FindPkgConfig
      a pkg-config module for CMake
 
     
 
      Usage:
 
          pkg_check_modules(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*)
            checks for all the given modules
 
     
 
          pkg_search_module(<PREFIX> [REQUIRED] <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
 
      It sets the following variables:
 
          PKG_CONFIG_FOUND        ... true iff pkg-config works on the system
          PKG_CONFIG_EXECUTABLE    ... pathname of the pkg-config program
          <PREFIX>_FOUND          ... set to 1 iff module(s) exist
 
     
 
      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>_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_OTHERS ... all other linker flags
          <XPREFIX>_INCLUDE_DIRS  ... the '-I' preprocessor flags (w/o the '-I')
          <XPREFIX>_CFLAGS        ... all required cflags
          <XPREFIX>_CFLAGS_OTHERS  ... 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)
            defines e.g.:
              XRENDER_LIBRARIES=Xrender;X11
              XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp
 
     
 
          pkg_search_module (BAR    libxml-2.0 libxml2 libxml>=2)
 
 
  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
 
     
 
 
  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:
 
        PYTHON_LIBRARIES    = path to the python library
        PYTHON_INCLUDE_PATH  = path to where Python.h is found
        PYTHON_DEBUG_LIBRARIES = path to the debug library
 
     
 
 
  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.
 
     
 
      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.  First is QT_USE_FILE which is the
      path to a CMake file that can be included to compile Qt 4 applications
      and libraries.  By default, the QtCore and QtGui libraries are loaded.
      This behavior can be changed by setting one or more of the following
      variables to true:
 
                          QT_DONT_USE_QTCORE
                          QT_DONT_USE_QTGUI
                          QT_USE_QT3SUPPORT
                          QT_USE_QTASSISTANT

                          QT_USE_QTNETWORK
                          QT_USE_QTNSPLUGIN
                          QT_USE_QTOPENGL
                          QT_USE_QTSQL
                          QT_USE_QTXML
                          QT_USE_QTSVG
                          QT_USE_QTTEST
                          QT_USE_QTUITOOLS
 
     
 
      All the libraries required are stored in a variable called
      QT_LIBRARIES.  Add this variable to your TARGET_LINK_LIBRARIES.

  FindRuby
      Find Ruby
 
      This module finds if Ruby 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:
 
        RUBY_INCLUDE_PATH = path to where ruby.h can be found
        RUBY_EXECUTABLE  = full path to the ruby binary
 
 
  FindSDL
      Locate the SDL library
 
      This module defines
 
        SDL_LIBRARY, the library to link against
        SDL_FOUND, if false, do not try to link to SDL
        SDL_INCLUDE_DIR, where to find SDL.h
 
     
 
      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.
      $SDLDIR is an environment variable that would correspond to the
      ./configure --prefix=$SDLDIR used in building SDL.  l.e.galup 9-20-02
 
      Modified by Eric Wing.  Added 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.
 
      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_image
      Locate SDL_image library
 
      This module defines
 
        SDLIMAGE_LIBRARY, the library to link against
        SDLIMAGE_FOUND, if false, do not try to link to SDL
        SDLIMAGE_INCLUDE_DIR, where to find SDL/SDL.h
 
     
 
      $SDLDIR is an environment variable that would correspond to the
      ./configure --prefix=$SDLDIR used in building SDL.

      additional Unix paths (FreeBSD, etc).
 
  FindSDL_mixer
      Locate the SDL_mixer library
 
      This module defines

        SDLNET_INCLUDE_DIR, where to find the headers
       
 
      $SDLDIR is an environment variable that would correspond to the
      ./configure --prefix=$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).  On OSX, this will prefer the
      Framework version (if found) over others.  People will have to
      manually change the cache values of SDLNET_LIBRARY to override this
      selection.
 
  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
      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.
 
      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 selection.
 
 
  FindSDL_ttf
      Locate SDL_ttf library
 
      This module defines
 
        SDLTTF_LIBRARY, the library to link against
        SDLTTF_FOUND, if false, do not try to link to SDL
        SDLTTF_INCLUDE_DIR, where to find SDL/SDL.h
         
 
      $SDLDIR is an environment variable that would correspond to the
      ./configure --prefix=$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).  On OSX, this will prefer the Framework version (if
      found) over others.  People will have to manually change the cache
      values of SDLTTF_LIBRARY to override this selection.

      PowerPC toolchain for the directory where it is called
 
      It contains the following variables: ECOS_DEFINITIONS
      ECOSCONFIG_EXECUTABLE for internal use only:
 
        ECOS_ADD_TARGET_LIB
 
 
  UsePkgConfig
      pkg-config module for CMake
 
     
 
      Defines the following macros:
 
      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.
 
  Use_wxWindows
      ---------------------------------------------------
 
     
 
      This convenience include finds if wxWindows is installed and set the
      appropriate libs, incdirs, flags etc.  author Jan Woetzel <jw -at-
      mip.informatik.uni-kiel.de> (07/2003)
 
      USAGE:
 
          just include Use_wxWindows.cmake
          in your projects CMakeLists.txt
 
      INCLUDE( ${CMAKE_MODULE_PATH}/Use_wxWindows.cmake)
 
      if you are sure you need GL then
 
        SET(WXWINDOWS_USE_GL 1)
 
      *before* you include this file.
 
      16.Feb.2004: changed INCLUDE to FIND_PACKAGE to read from users own
      non-system CMAKE_MODULE_PATH (Jan Woetzel JW) 07/2006: rewrite as
      FindwxWidgets.cmake, kept for backward compatibilty JW
 
  UsewxWidgets
      Convenience include for using wxWidgets library
 
      Finds if wxWidgets is installed and set the appropriate libs, incdirs,
      flags etc.  INCLUDE_DIRECTORIES, LINK_DIRECTORIES and ADD_DEFINITIONS
      are called.
 
      USAGE
 
        SET( wxWidgets_USE_LIBS  gl xml xrc ) # optionally: more than wx std libs
        FIND_PACKAGE(wxWidgets REQUIRED)
        INCLUDE( ${xWidgets_USE_FILE} )
        ... add your targets here, e.g. ADD_EXECUTABLE/ ADD_LIBRARY ...
        TARGET_LINK_LIBRARIERS( <yourWxDependantTarget>  ${wxWidgets_LIBRARIES})
 
     
 
      DEPRECATED
 
        LINK_LIBRARIES is not called in favor of adding dependencies per target.
