CMAKE in my OpenCV 4.2.0 source code couldn't find any cuDNN installed in my machine
I'm compiling OpenCV4.2 on Ubuntu 20.4 following this tutorial https://www.pyimagesearch.com/2020/02/03/how-to-use-opencvs-dnn-module-with-nvidia-gpus-cuda-and-cudnn/
I did make sure to download cudnn-11.2-linux-x64-v8.1.0.77.tgz for my CUDA 11.2, extract it, and copy all the files to the appropriate folders in /usr/local/cuda/lib64 and /usr/local/cuda/include
I run CMAKE in the /build folder of opencv source code like this:
cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D INSTALL_C_EXAMPLES=OFF \
-D OPENCV_ENABLE_NONFREE=ON \
-D WITH_CUDA=ON \
-D WITH_CUDNN=ON \
-D OPENCV_DNN_CUDA=ON \
-D ENABLE_FAST_MATH=1 \
-D CUDA_FAST_MATH=1 \
-D CUDA_ARCH_BIN=5.0 \
-D WITH_CUBLAS=1 \
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules \
-D HAVE_opencv_python3=ON \
-D PYTHON_EXECUTABLE=~/.virtualenvs/opencv_cuda/bin/python \
-D BUILD_EXAMPLES=ON \
-D CUDNN_LIBRARY=/usr/local/cuda/lib64/ \
-D CUDNN_INCLUDE_DIR=/usr/local/cuda/include ..
However the output log of CMAKE shows cuDNN is NO, this is the snippet of the errors:
-- Could NOT find CUDNN: Found unsuitable version "..", but required is at least "7.5" (found /usr/local/cuda/lib64/libcudnn.so)
-- CUDA detected: 11.2
-- CUDA NVCC target flags: -gencode;arch=compute_50,code=sm_50;-D_FORCE_INLINES
And here is the full configuration output

This is frustrating since the cmake file could detect my CUDA, but couldn't find my CUDNN
Is there any fix I can make since I'm sure a lot have encountered this error as well

It turns out this issue was caused by OpenCV 4.2 itself, updating to version 4.5.1, the latest as of Feburary 2021 solved the issue of not detecting cuDNN (also a reminder that OPENCV 4.5 is not compatible with gcc > 8 so downgrade your gcc to 8 and sym link it before attempting to compile )
