一个错误输出中的正在查找glXGetProcAddressEXT-未找到，并且日志文件表明libGL存在链接错误。

One of the error outputs was Looking for glXGetProcAddressEXT - not found, and the log files indicated that there was a linking error with libGL.

然后我尝试运行 apt-get install glfw 以打印出依赖项列表。即使它是 apt-get 中的较旧版本，它仍然列出了一些必须安装的依赖项。

I then tried running apt-get install glfw to print out the list of dependencies. Even though it was an older version in apt-get, it still listed some dependencies that had to be installed.

GLFW在安装 libglu1-mesa-dev 和 libgl1-mesa-dev

最后一条错误消息 CMake错误：此项目中使用了以下变量，但是将它们设置为NOTFOUND。
请设置它们或确保已在CMake文件中对其进行正确设置和测试：
OPENGL_glu_LIBRARY（高级）是使我失望的一个。我以为这是路径和环境变量的问题

The last error message 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) was the one that threw me off. I thought it was a problem with paths and environment variables
