The OpenGL Samples Pack 2.1 is a collection of OpenGL 2.1 samples... So after OpenGL 3.3 samples I do downgrades? Yes!
This first version 2.1.0.0 is a Windows (and probably Linux) release but the goal is to bring the samples pack on MacOS X for next release. Because of Apple exclusively, MacOS X is way behind Windows and Linux in matter of OpenGL support and remains stock to OpenGL 2.1 + extensions... not cool!
I still have trouble to use CMake on MacOS X with OpenGL... if anyone has an experience in this area, please send me a mail! Thanks in advance!
