I had to add set(CMAKE_CUDA_ARCHITECTURES "native") to the CMakeLists.txt file. Otherwise, I got the following error, "CMAKE_CUDA_ARCHITECTURES must be non-empty if set".

Besides that, the build worked, and I was able to run the program.

CMAKE_CUDA_ARCHITECTURES are set in here. If you need to set that, your cmake configure command must've failed while detecting CUDA, right?

Yes, that is correct. It failed as soon as it reached line 156 enable_language(CUDA).
