			# Try to find gnu scientific library GSL
			# See

			#
			# Once run this will define:
			#
			# GSL_FOUND = system has GSL lib
			#
			# GSL_LIBRARIES = full path to the libraries
			# on Unix/Linux with additional linker flags from "gsl-config --libs"
			#
			# CMAKE_GSL_CXX_FLAGS = Unix compiler flags for GSL, essentially "`gsl-config --cxxflags`"
			#
			# GSL_INCLUDE_DIR = where to find headers
			#
			# GSL_LINK_DIRECTORIES = link directories, useful for rpath on Unix
			# GSL_EXE_LINKER_FLAGS = rpath on Unix
