尝试在启用GPU的情况下安装yolo34py时收到错误“OpenCV 4.x+需要启用的C++11支持”

Question

根据https://github.com/madhawav/YOLO3-4-Py上的说明从源代码进行安装

我已经找到了“OpenCV 4.x+需要启用C++11支持”错误的解决方案，该错误表示我应该在Makefile中的g++编译器命令中添加-std=C++11标志。但是，我在克隆的git存储库中没有看到Makefile。有没有办法通过setup.py文件添加标志？或者是其他什么原因导致了这个错误

从/src运行pip install .时的终端输出：

  DEPRECATION: A future pip version will change local packages to be built in-place without first copying to a temporary directory. We recommend you use --use-feature=in-tree-build to test your packages with this new behavior before it becomes the default.
   pip 21.3 will remove support for this functionality. You can find discussion regarding this at https://github.com/pypa/pip/issues/7555.
