为了在CodeBlocks中使用OpenGl，我很难获得正确的设置。 我正在关注本教程： https://www.youtube.com/watch?v=XlMEK58FaGM 而且我已经做了那个家伙所做的一切。 但是，当我尝试测试他的代码时，出现了致命错误：
C:\Users\cristina\Desktop\università pdf\programmazione\Progetti SFML su CodeBlocks\OpenGL\main.cpp:4:21: fatal error: GL/glew.h: No such file or directory
compilation terminated.
Process terminated with status 1 (0 minute(s), 0 second(s))
1 error(s), 0 warning(s) (0 minute(s), 0 second(s))
这是我尝试运行的代码：

我正在使用：CodeBlocks 17.12，Glew 2.1.0，glm 0.9.8.5，sfml 2.5.0
因此，我在观看该视频后所做的是：
我已经复制并粘贴了glew2.0.0/include/GL的文件
将Glew文件夹放入CodeBlocks的MinGW/Include/GL文件中；
我已经将glm文件从glm文件夹复制并粘贴到了
MinGW/include个CodeBlocks文件；
build options/OpenGL/search directory/linker/add和我
添加了glew2.0.0/lib/release/Win32； build options/OpenGL/linker setting/add 3个库按此顺序：glew32.dll中的glew2.0.0/bin/release/win32复制并粘贴到build options/OpenGL/#defines GLEW_STATIC。我不明白自己做错了什么，请帮助我。
