Steps to reproduce
CMake options that work:
cmake -DBUILD_opencv_cudacodec=OFF -DBUILD_opencv_cudaoptflow=OFF -DPYTHON3_EXECUTABLE=which python3.8 -DPYTHON_DEFAULT_EXECUTABLE=which python3.8 -DWITH_CUDA=ON -DCUDA_ARCH_BIN=61 -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules/ ../opencv-master
CMake options that doe not:
cmake -DBUILD_opencv_cudaoptflow=OFF -DPYTHON3_EXECUTABLE=which python3.8 -DPYTHON_DEFAULT_EXECUTABLE=which python3.8 -DWITH_CUDA=ON -DCUDA_ARCH_BIN=61 -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules/ ../opencv-master

Issue submission checklist
- I report the issue, it's not a question
- I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
- I updated to the latest OpenCV version and the issue is still there
- There is reproducer code and related data files (videos, images, onnx, etc)
