About nigels-com/glew
The OpenGL Extension Wrangler Library (GLEW) is a cross-platform open-source C/C++ extension loading library. It provides efficient run-time mechanisms for determining which OpenGL extensions are supported on the target platform. OpenGL core and extension functionality is exposed in a single header file. GLEW has been tested on a variety of operating systems including Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris. The library is built using GNU make or CMake and includes utility programs like glewinfo and visualinfo.
