| # ----------- |
| # |
| # 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) |
| # |
| # |
