#
# This module finds if kgfo 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:
#
#  KGFO_FOUND        = system has kgfo and it should be used
#  KGFO_LIBRARIES         = full path to the kgfo library and linker flags on unix
#  CMAKE_KGFO_CXX_FLAGS        = compiler flags for building kgfo 
#  KGFO_INCLUDE_DIR    = include path of kgfo
