First off, thanks a ton for your help cudawarped!
Unfortunately, now I’m having trouble installing the SDK. I followed the readme, but something seems to be missing. I’ve solved a few issues by modifying the cmake command.
Trying to build NVIDIA VIDEO CODEC SDK:
$ cmake -DCMAKE_BUILD_TYPE=Release \
-DCMAKE_LIBRARY_PATH=/usr/local/cuda/lib64/stubs \
-DCUDA_CUDA_LIBRARY=/usr/local/cuda/lib64/stubs/libcuda.so ..
But I can’t get past the following error message.
Error when installing NVIDIA VIDEO CODEC SDK:

The only CUVID I could find while building OpenCV is WITH_NVCUVID. So I tried adding that to the cmake command as well. No luck.
I built openCV as follows:
cmake \
-DWITH_CUDA=ON \
-DBUILD_CUDA_STUBS=ON \
-DWITH_NVCUVID=ON \
-DWITH_OPENGL=ON \
-DWITH_QT=ON \
-DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib-master/modules \
-DCMAKE_LIBRARY_PATH=/usr/local/cuda/lib64/stubs \
-DCMAKE_C_COMPILER=$(which gcc-8) \
-DCMAKE_CXX_COMPILER=$(which g++-8) \
../opencv-master

PS: Of course I found the ‘TODO: other options: WITH_CUFFT , WITH_CUBLAS , WITH_NVCUVID ?’ in the config reference, which is ironic.
