Travis CI with CUDA 11 (and maybe Windows)

Has anyone had experience with writing up a .travis.yml file for configuring Travis CI to test build with CUDA 11.x ? It seems the file paths are slightly different now, so my own file can’t be easily adapted.

I’ve also been scratching my head about how to get CUDA installed on Travis’ Windows machines, but I don’t even know how to properly do multi-platform .travis.yml files without CUDA, let alone with it.

Bump.
