OpenGL參考

Windows SDK which includes OpenGL and GLU (OpenGL Utility). The Visual C++ 2010 Express bundles the Microsoft Windows SDK, which would be installed in "C:\Program Files\Microsoft SDKs\Windows\v7.0A". (Otherwise, you need to download and install the Windows SDK separately).
The followings are used from Windows SDK:

• gl.h, glu.h: header for OpenGL and GLU in directory "C:\Program Files\Microsoft SDKs\Windows\v7.0A\include\gl".
• opengl32.lib, glu32.lib: libraries for OpenGL and GLU in directory "C:\Program Files\Microsoft SDKs\Windows\v7.0A\lib".
• opengl32.dll, glu32.dll: dynamic link libraries for OpenGL and GLU in directory "C:\Windows\System32". This directory is to be included in PATH environment variable.

你可以把它放在與exe檔在一起
