Building dependencies fails for OpenCV - What path statements are the correct one?

[PeterCodar]

I try to follow your building steps for OpenCV https://github.com/theophanemayaud/video-simili-duplicate-cleaner/blob/master/DEPENDENCIES.md#opencv

One or more of the path statements seems not to work correctly. I only get these errors

CMake Error: The source directory "C:/Dev/msys64/home/QT/opencv_build/^" does not exist.
Specify --help for usage, or press the help button on the CMake GUI.

"C:\Dev\opencv"

Which path do I have to adjust?

BTW: I'm 100% sure that C:/Dev/msys64/home/QT/opencv_build/ exists. "QT" is the name of the current user.

But it is true that C:/Dev/opencv_install does not exist, only this path C:/Dev/msys64/home/QT/opencv_install/
