Here is the error I am getting when I am compiling OpenCV on ubuntu 20.04 with cuda 10.1.

Here are my cmake flags:
cmake -D CMAKE_BUILD_TYPE=RELEASE
-D CMAKE_INSTALL_PREFIX=/usr/local
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules
-D BUILD_TIFF=ON
-D WITH_FFMPEG=ON

-D CUDNN_INCLUDE_DIR=/usr/lib/cuda/include
-D BUILD_EXAMPLES=OFF
-D PYTHON_DEFAULT_EXECUTABLE=$(which python3) ..
It works perfectly with the option -D OPENCV_DNN_CUDA=OFF. But I need CUDA libraries. My CUDA and CUDNN paths are correct, so I have no idea what is wrong with the cmake compilation. Did anyone face with a similar problem when installing opencv?
Note: I am following this link to finally install caffe.
