python - CMake在Python Virtualenv中安装DLib时找不到C和C++编译器

Question

看完有关使用Python进行面部识别的教程之后，我设法在Linux笔记本电脑上编写了工作程序。今天，我试图在Windows 10 PC上做同样的事情，但是当尝试使用以下代码从源代码安装DLib时，我总是遇到错误:

python setup.py install

我收到的错误消息是这样的:

running install

我已经安装了VS 16 2019，并且使用Windows安装程序和VS工具安装了CMake。
我知道问题出在编译器上，但是我该如何安装一个并将CMake指向它呢？

我遵循了使用Visual Studio安装C++编译器的过程，本文已对此进行了详细介绍。之后，我运行python setup.py install，一切正常。

感谢斯塔克!
