Cmake for Linux

[ghost]

Hi,
Thanks for the great example.
I am breaking my head to make this work on Linux. No matter what i do, I get:
Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)

This is the make file:

Hello,

I got it building and working on Linux, using OpenGL 3.2 and 3.3 (no 4.x yet, sorry), cmake 3.5.1 + libGLEW + libGL + lbglfw3.

The attached patch (under MIT license) contains everything (including building instructions on Debian like distribution), and should not break the Mac OS X build imho.

Is there something wrong with the patch ?

[morizotter]

I just "looking" 😊
