  1. - Find LibSVM
  2. LibSVM is a Library for Support Vector Machines
  3. available at http://www.csie.ntu.edu.tw/~cjlin/libsvm/
  4. The module defines the following variables:
  5. LIBSVM_FOUND - the system has LibSVM
  6. LIBSVM_INCLUDE_DIR - where to find svm.h
  7. LIBSVM_INCLUDE_DIRS - libsvm includes
  8. LIBSVM_LIBRARY - where to find the LibSVM library
  9. LIBSVM_LIBRARIES - aditional libraries
  10. LIBSVM_MAJOR_VERSION - major version
  11. LIBSVM_MINOR_VERSION - minor version
  12. LIBSVM_PATCH_VERSION - patch version
  13. LIBSVM_VERSION_STRING - version (ex. 2.9.0)
  14. LIBSVM_ROOT_DIR - root dir (ex. /usr/local)

  1. set LIBSVM_INCLUDE_DIR

find_path ( LIBSVM_INCLUDE_DIR

 NAMES
   svm.h
 PATHS
   ${LIBSVM_ROOT_DIR}/include
 PATH_SUFFIXES
   libsvm
   libsvm-2.0/libsvm
 DOC
   "LibSVM include directory"

)


  1. set LIBSVM_INCLUDE_DIRS

if ( LIBSVM_INCLUDE_DIR )

 set ( LIBSVM_INCLUDE_DIRS ${LIBSVM_INCLUDE_DIR} )

endif ()


  1. version

set ( _VERSION_FILE ${LIBSVM_INCLUDE_DIR}/svm.h ) if ( EXISTS ${_VERSION_FILE} )

 # LIBSVM_VERSION_STRING macro defined in svm.h since version 2.8.9
 file ( STRINGS ${_VERSION_FILE} _VERSION_STRING REGEX ".*define[ ]+LIBSVM_VERSION[ ]+[0-9]+.*" )
 if ( _VERSION_STRING )
   string ( REGEX REPLACE ".*LIBSVM_VERSION[ ]+([0-9]+)" "\\1" _VERSION_NUMBER "${_VERSION_STRING}" )
   math ( EXPR LIBSVM_MAJOR_VERSION "${_VERSION_NUMBER} / 100" )
   math ( EXPR LIBSVM_MINOR_VERSION "(${_VERSION_NUMBER} % 100 ) / 10" )
   math ( EXPR LIBSVM_PATCH_VERSION "${_VERSION_NUMBER} % 10" )
   set ( LIBSVM_VERSION_STRING "${LIBSVM_MAJOR_VERSION}.${LIBSVM_MINOR_VERSION}.${LIBSVM_PATCH_VERSION}" )
 endif ()

endif ()


  1. check version

set ( _LIBSVM_VERSION_MATCH TRUE ) if ( LibSVM_FIND_VERSION AND LIBSVM_VERSION_STRING )

 if ( LibSVM_FIND_VERSION_EXACT )
   if ( NOT ${LibSVM_FIND_VERSION} VERSION_EQUAL ${LIBSVM_VERSION_STRING} )
     set ( _LIBSVM_VERSION_MATCH FALSE )
   endif ()
 else ()
   if ( ${LibSVM_FIND_VERSION} VERSION_GREATER ${LIBSVM_VERSION_STRING} )
     set ( _LIBSVM_VERSION_MATCH FALSE )
   endif ()
 endif ()

endif ()


  1. set LIBSVM_LIBRARY

find_library ( LIBSVM_LIBRARY

 NAMES
   svm
 PATHS
   ${LIBSVM_ROOT_DIR}/lib
 DOC
   "LibSVM library location"

)


  1. set LIBSVM_LIBRARIES

set ( LIBSVM_LIBRARIES ${LIBSVM_LIBRARY} )

  1. link with math library on unix

if ( UNIX )

 list ( APPEND LIBSVM_LIBRARIES "-lm" )

endif ()


  1. try to guess root dir from include dir

if ( LIBSVM_INCLUDE_DIR )

 string ( REGEX REPLACE "(.*)/include.*" "\\1" LIBSVM_ROOT_DIR ${LIBSVM_INCLUDE_DIR} )
  1. try to guess root dir from library dir

elseif ( LIBSVM_LIBRARY )

 string ( REGEX REPLACE "(.*)/lib[/|32|64].*" "\\1" LIBSVM_ROOT_DIR ${LIBSVM_LIBRARY} )

endif ()


  1. handle REQUIRED and QUIET options

include ( FindPackageHandleStandardArgs ) find_package_handle_standard_args ( LibSVM DEFAULT_MSG LIBSVM_LIBRARY

 _LIBSVM_VERSION_MATCH
 LIBSVM_INCLUDE_DIR
 LIBSVM_INCLUDE_DIRS
 LIBSVM_LIBRARIES
 LIBSVM_ROOT_DIR

)


mark_as_advanced (

 LIBSVM_LIBRARY
 LIBSVM_LIBRARIES
 LIBSVM_INCLUDE_DIR
 LIBSVM_INCLUDE_DIRS
 LIBSVM_ROOT_DIR
 LIBSVM_VERSION_STRING
 LIBSVM_MAJOR_VERSION
 LIBSVM_MINOR_VERSION
