基於cmake編譯glew

cmake已經成爲了C/C++開源項目的主流構建工具。glew也提供了cmake的腳本，但用cmake編譯glew容易採坑：glew的github上的代碼，不管是master分支仍是glew-2.1.0這個tag，都沒法正確用cmake編譯（Linux、OSX親測，均失敗）；必須從sourceforge上下載glew，sourceforge下載的glew-2.1.0.tgz才能被cmake正確編譯。

tar -zxvf glew-2.1.0.tgz
cd glew-2.1.0
cd build
mkdir linux
cd linux
cmake ../cmake -DCMAKE_INSTALL_PREFIX=./install
make

你個混球，@Nigel Stewart，浪費我時間。

p.s. 若是cmake報錯提示：
Could NOT find OpenGL (missing: OPENGL_opengl_LIBRARY OPENGL_glx_LIBRARY
OPENGL_INCLUDE_DIR)

則須要安裝：
sudo apt-fast install libgl1-mesa-dev

若是cmake報錯提示：
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
OPENGL_glu_LIBRARY (ADVANCED)

則須要安裝：
sudo apt-get install libglu1-mesa-dev
