Since commit d74210a8bd (CMP0017: Remove support for OLD behavior,
2024-11-17) we can rely on CMP0017's NEW behavior unconditionally.
Calling `include(FindPackageHandleStandardArgs)` in a builtin module
will always get the builtin `FindPackageHandleStandardArgs`.

FindGnuplot
|
|
-----------
|
|
|
|
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.
