Install Gnuplot but still giving this error "Could NOT find Gnuplot (missing: GNUPLOT_EXECUTABLE)"

Hello @tohidarehman1988,

Are you sure Gnuplot is well installed ?
To test this you can try:

gnuplot --version

From what I can see, GNUPLOT_EXECUTABLE is set by: https://cmake.org/cmake/help/latest/module/FindGnuplot.html
So maybe setting this variable in the CmakeList can fix your issue ?

You can find the path to the gnuplot executable using:

which gnuplot

Cheers,
Cyril

Can you try to run the command I have send you ? CMake recquires gnuplot and it looks like pygnuplot install it in a path which is not available to Cmake.
