    #  -- Try to find LibSVM
    #
    #  LibSVM is a Library for Support Vector Machines
    #  available at http://www.csie.ntu.edu.tw/~cjlin/libsvm/
    #
    #  ------------------------------------------------------------------
    #
    #  -- Library usage example :
    #
    #  find_package (LibSVM 2.9.0)
    #  if (LibSVM_FOUND)
    #    include_directories (${LibSVM_INCLUDE_DIRS})
    #    add_executable (foo foo.cpp)
    #    target_link_libraries (foo ${LibSVM_LIBRARIES})
    #  endif ()
    #
    #  -- Show some debug information :
    #
    #  set (LibSVM_DEBUG TRUE)
    #  find_package (LibSVM)
    #
    #  -------------------------------------------------------------------
    #
    #  -- This module defines :
    #
    #  LibSVM_FOUND - the system has LibSVM
    #  LibSVM_INCLUDE_DIR - where to find svm.h
    #  LibSVM_INCLUDE_DIRS libsvm includes
    #  LibSVM_LIBRARY - where to find the LibSVM library
    #  LibSVM_LIBRARIES - aditional libraries
    #  LibSVM_VERSION - library version
    #  LibSVM_MAJOR_VERSION
    #  LibSVM_MINOR_VERSION
    #  LibSVM_SUBMINOR_VERSION
