| ----------- |
| |
| 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. |
