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

# Based on a script of Felix Woelk and Jan Woetzel
# (www.mip.informatik.uni-kiel.de)
#
# It defines the following variables:
# GSL_FOUND - system has GSL lib
# GSL_INCLUDE_DIRS - where to find headers
# GSL_LIBRARIES - full path to the libraries
# GSL_LIBRARY_DIRS, the directory where the PLplot library is found.
# CMAKE_GSL_CXX_FLAGS = Unix compiler flags for GSL, essentially "`gsl-config --cxxflags`"
# GSL_LINK_DIRECTORIES = link directories, useful for rpath on Unix
# GSL_EXE_LINKER_FLAGS = rpath on Unix
