   #  -- 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
