1.5. GLEW（OpenGL Extension Wrangler Library）
GLEW is an open-source cross-platform extension loading library with thread-safe support for multiple rendering contexts and automatic code generation capability. GLEW provides easy-to-use and efficient methods for checking OpenGL extensions and core functionality.
GLEW是一个跨平台的C++扩展库，基于OpenGL图形接口。使用OpenGL的朋友都知道，window目前只支持OpenGL1.1的函数，但 OpenGL现在都发展到2.0以上了，要使用这些OpenGL的高级特性，就必须下载最新的扩展，另外，不同的显卡公司，也会发布一些只有自家显卡才支持的扩展函数，你要想用这数函数，不得不去寻找最新的glext.h,有了GLEW扩展库，你就再也不用为找不到函数的接口而烦恼，因为GLEW能自动识别你的平台所支持的全部OpenGL高级扩展函数。也就是说，只要包含一个glew.h头文件，你就能使用gl,glu,glext,wgl,glx的全部函数。GLEW支持目前流行的各种操作系统（including Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris）。
