#
# This module finds if GSLOBJ 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:
#
#  GSLOBJ_FOUND        = system has GSLOBJ and it should be used
#  GSLOBJ_LIBRARIES         = full path to the GSLOBJ library and linker flags on unix
#  CMAKE_GSLOBJ_CXX_FLAGS        = compiler flags for building GSLOBJ 
#  GSLOBJ_INCLUDE_DIR    = include path of GSLOBJ
