I installed CUDA 10.2, and installed matching CUDNN, but CMAKE cannot recognize it while I try to install OpenCV with CUDA. I already copied Cudnn files from bin, include, and lib folders to the corresponding CUDA folders. I tried several versions of Cudnn, but I still get the same error.
Here is CMAKE's configuring output:

I found the solution for a similar problem in the following link: https://forums.developer.nvidia.com/t/cudnn-found-but-version-cant-be-deduced/145551/12?u=hedeya1980
So, I changed the following line in 'opencv-4.1.1\cmake':
file(READ "${CUDNN_INCLUDE_DIR}/cudnn.h" CUDNN_H_CONTENTS)
to be as follows:
