## Try to find gnu scientific library GSL
|
|
## (see http://www.gnu.org/software/gsl/)
|
|
## 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
