# Try to find gnu scientific library GSL
# See
# http://www.gnu.org/software/gsl/ and
# http://gnuwin32.sourceforge.net/packages/gsl.htm
#
# 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
