import cv2 error on windows: missing configuration files

edit

OpenCV = from master branch 7/10/20 Operating System / Platform => Windows 64 Bit Win10 Compiler => Visual Studio 2019

problem: I successfully built opencv in the latest cmake, and then built in VS. My PC recognizes python but does not recognize cv2. I installed both opencv and python in the c:\ drive. I tried adding these paths to my user environment variables, no luck. All my python paths in cmake are also correct. What could be the problem here?

error:
