CUDA support

[vladsterz]

Hats off for the amazing tool.

So I am running into an issue where the CUDA files I add to the project are not detected as *.cu files by the VisualStudio which (I think)
leads to the recompilation of the *.cu files every time I change anything (not the *.cu files, a *.cpp file for example).
Is there a standard way to add the *.cu files to my project? Or at least some cues.
Thank you
