0002 ## Try to find gnu scientific library GSL
0003 ## (see http://www.gnu.org/software/gsl/)
0004 ## Once run this will define:
0005 ##
0006 ## GSL_FOUND = system has GSL lib
0007 ##
0008 ## GSL_LIBRARIES = full path to the libraries
0009 ## on Unix/Linux with additional linker flags from "gsl-config --libs"
0010 ##
0011 ## CMAKE_GSL_CXX_FLAGS = Unix compiler flags for GSL, essentially "`gsl-config --cxxflags`"
0012 ##
0013 ## GSL_INCLUDE_DIR = where to find headers
0014 ##
0015 ## GSL_LINK_DIRECTORIES = link directories, useful for rpath on Unix
0016 ## GSL_EXE_LINKER_FLAGS = rpath on Unix
