<nowiki># - 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)
