The OpenGL Extension Wrangler Library (GLEW) is a cross-platform open-source C/C++ extension loading library.
GLEW 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.
Version 1.5.4 adds support for OpenGL 3.3, OpenGL 4.0 and new vendor, EXT and ARB extensions.
