Don't forget to add /m to your msbuild command to utilize multiple CPU cores

OpenCV is sick, it does not build with CUDA support, so many errors during compile.

Thank you for comprehensive explanation, Abubakir! I try to build opencv420+contrib, CMake stage passed OK, but building opencv.sln as taken BUILD_ALL failed. "Cannot find opencv_dnn420.lib". But it is my goal! Are you sure, that Visual Studio 2015 (my case) will not do?

Hello. I've been trying to bind this version with my python. Unfortunately i have not been able to do it. When import Opencv in any of my environments i still have the old version.

[mohamedhedeya]

At the beginning, I got configuration errors that couldn't be solved until I used opencv_contrib-4.1.1 instead of opencv_contrib-master.
Then, the following build errors occurred. Could you pls help advise how to solve?
