Hi, without your cmake command it is difficult to be 100% certain exactly what the problem is, that said looking at the error it is most likely that you have enabled CUDA without adding the path to the OpenCV contrib repository which contains the code for the CUDA modules. I would suggest following this or similar guides if you are unsure of how to compile OpenCV with CUDA on Windows.
