Issue building NIX-MX on macOS

[vidaurre]

Hi,

this is a probably a trivial issue (apologies) but I'm having troubles building NIX-MX on macOS, as per the instructions here: https://github.com/G-Node/nix-mx/blob/master/MacOSBuild.md

In particular cmake complains "No computing environment found! Install GNU Octave (or MathWorks MATLAB)."

But my Matlab is in place here: /Applications/MATLAB_R2020b.app/bin/matlab, and my PATH contains /Applications/MATLAB_R2020b.app/bin:/Applications/MATLAB_R2020b.app.
CMakeOutput.log doesn't seem to offer much useful information.

Is there any way to inform cmake of where is Matlab properly?

I'm using macOS Catalina if that's of any use.

Many thanks!!

I see that the precompiled MEX files work for me, but maybe the question is still useful for other people with different environments..

Thanks for the issue report! I think it is an easy fix but updating the CMake code that detects Matlab:

nix-mx/cmake/FindMATLAB.cmake

Line 129 in 018db81

sorry for the delay, yes this is the reoccurring issue with the new Matlab version. See also #172
Unfortunately, I do not have a more recent version than the 2020a. If you can build it successfully with a newer version one could simply extend the line.
