c:\opencv\opencv4.2.0\download\opencv-4.2.0\modules\dnn\src\cuda\execution.hpp:52: error: (-217:Gpu API call) invalid device function in function 'cv::dnn::cuda4dnn::csl::make_policy'
==================================================
"invalid device function" means that CUDA binary code is not supported on your current GPU. Please check CUDA_ARCH_BIN CMake variable, it must contain actual compute capability of your card. For the list of compute capabilities per card please refer to https://developer.nvidia.com/cuda-gpus.
----------------------------------------------------------------
Seems fixed. Changed CUDA_GENERATION=AUTO and added 5.2 and 3.5 to CUDA_ARCH_BIN.
