# Once done this will define

# EXPAT_FOUND - System has Expat
# EXPAT_INCLUDE_DIR - The Expat include directory
# EXPAT_LIBRARIES - The libraries needed to use Expat
# EXPAT_DEFINITIONS - Compiler switches required for using Expat
# EXPAT_VERSION_STRING - the version of Expat found (since CMake 2.8.8)
# use pkg-config to get the directories and then use these values
# in the find_path() and find_library() calls
