Issue Description

I'm building the sdk with the Cuda flag and I ran into a problem where I had to manually add the
Cuda_toolkit_root_dir -
I downloaded the latest Cuda and the path is
C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.6

I was also missing(according to cmake) the Cuda sdk location. After some research I found that "samples" was the sdk location so for
Cuda_sdk_root_dir I added
C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.6/extras/CUPTI
I also tried with the sdk_root_dir empty.
I don't think the variable is important but IDK?

The files generated but I got this warning:

 CMake Warning (dev) in CMakeLists.txt  
Policy CMP0104 is not set: CMAKE_CUDA_ARCHITECTURES now detected for NVCC,
  empty CUDA_ARCHITECTURES not allowed.

I researched further and was suggested
cmake --help-policy CMP0104 - which showed a large text block about deprecation after v3.18... I didn't understand the implications.

Does this warning mean Cuda has not been enabled with realsense?

Thanks.

Is there a test script to see if Cuda is being used?
