   1 #
   2 # This module finds if GSL is installed and determines where the
   3 # include files and libraries are. It also determines what the name of
   4 # the library is. This code sets the following variables:
   5 #
   6 #  GSL_FOUND        = system has GSL and it should be used
   7 #  GSL_LIBRARIES         = full path to the GSL library and linker flags on unix
   8 #  CMAKE_GSL_CXX_FLAGS        = compiler flags for building GSL
   9 #  GSL_INCLUDE_DIR    = include path of GSL
