Opencv & blender issue in windows

hi there, I tried to run a tutorial that I followed Blender 2.8 facial mocap using OpenCV and webcam - YouTube
I have no idea about python or script, I made a little research and I found the solution for linux but not for windows , there was something called python.h that I have to make a path for, so here I stuck !
any ideas ?

The file python.h is part of the Python source code. The .h means it is a header file that contains definitions used by other parts of the program. Normally, you only need this for compiling C/C++ programs that use Python.

disclaimer: I did not take the time to watch the video.

There’s a patch for that ⚙ D12228 CMake: option to install Python headers but not solid enough reason to land it.
