Its hours that I'm trying to install mathgl but I'm having a lot of problems.
I tried compiling a simple c++ program just by including mgl2/mgl.h but I have errors.
It gives me fatal error: 'mgl2/mgl.h' file not found.
I have tried installing it with brew, and also downloading the single folder and placing it inside usr/local/include but it still doesn't work.
How can I install it cleanly and without having these errors?
