#
# This module finds if GLIB is installed and determines where the
# include files and libraries are. It also determines what the name of
# the library is. This code sets the following variables:
#
#  GLIB_FOUND           = system has GLIB and it should be used
#  GLIB_LIBRARIES       = full path to the GLIB library and linker flags on unix
#  CMAKE_GLIB_CXX_FLAGS = compiler flags for building GLIB 
#  GLIB_INCLUDE_DIR     = include path of GLIB
