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.
mesa-demos requires glew, so port it from OE, with the following changes:
- upgrade it from 1.5.1 to 1.5.7
- add license checksum
