安装OpenGL / GLUT并运行C程序？

Installing OpenGL/GLUT & running C program?

我是OpenGL和GLUT的新手，需要帮助来安装它们并在Visual C ++ 2010 Express Edition中运行hello.c(请参见下文)。

我正在使用Windows XP，并且在OpenGL Wiki上读取到我的计算机上已经安装了OpenGL库。结果，我只下载了Win32 dll，lib和头文件的GLUT并将其解压缩。

我有四个问题：

如果已经安装了OpenGL，如何找到它并在Visual C ++项目中使用它？

OpenGL Wiki提到opengl32.dll位于Windows / system32文件夹中-那么该dll如何处理？

我是否只将glut.h添加到Visual C ++解决方案资源管理器的头文件文件夹中？

我应该将glut32.dll，glut32.lib和glut.def放在哪里？

任何帮助将不胜感激。提前致谢。
