OpenCV Building with CUDA CUDNN - No CUDNN

For JetPack version, is there any where to learn it. I get a result there is no way to learn it as mentioned on How to check the JetPack Version

Also, i flashed JetPack 4.5.1 in Xavier by using the software in Nvidia website.

The CuDNN version is 8.0.0 by get to following

‘/usr/include/aarch64-linux-gnu/cudnn_version_v8.h’

directory.
