Let CMake handle CUDA requirements
Let CMake handle CUDA requirements

CMake should already know which versions of CUDA are required
depending on which standard is being used. The current setup
forbids compiling with C++17 for the host code and C++14 for
CUDA. This will require modifications in TMVA to work, but
relaxing this restriction will at least allow compilation of
ROOT with CUDA and C++17 when it's supported by Nvidia.
