Mac OS compilation

[gbittoun]

I tried to compile the samples on my Mac (OS X El Capitan version 10.11.6). By following the documentation, the cmake .. step worked fine but during compilation, I got the following error:

I looked for this egl.h file on my computer and it seems that it indeed doesn’t exist or at least, not in a directory named EGL. I could find it in the directory /opt/X11/include/GLES. I tried to copy it in the include dir of glxw… without success.

Is there a way to compile these examples on mac ? I don’t renounce to make them work, I’ll open a pull request if I find a correct way to fix this.
