  1. - Find LibSVM
 # LibSVM is a Library for Support Vector Machines
 # available at http://www.csie.ntu.edu.tw/~cjlin/libsvm/
 #
 # The module defines the following variables:
 #  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_MAJOR_VERSION - major version
 #  LIBSVM_MINOR_VERSION - minor version
 #  LIBSVM_PATCH_VERSION - patch version
 #  LIBSVM_VERSION_STRING - version (ex. 2.9.0)
 #  LIBSVM_ROOT_DIR - root dir (ex. /usr/local)
