# -----------
#
# this module looks for gnuplot
#
#
#
# Once done this will define
#
# ::
#
#   GNUPLOT_FOUND - system has Gnuplot
#   GNUPLOT_EXECUTABLE - the Gnuplot executable
#   GNUPLOT_VERSION_STRING - the version of Gnuplot found (since CMake 2.8.8)
#
#
#
# GNUPLOT_VERSION_STRING will not work for old versions like 3.7.1.
