[CMake] compiling .cpp/.cxx with CUDA compiler

[Kai Germaschewski]

Thank. Yeah, I've seen BLT through it's use in RAJA. You're right, it'd
work, but I'm reluctant to stray away from "vanilla" cmake too much, since
other people will have to deal with this code, and cmake itself is already
quite a step up from the regular Makefiles that they're used to.
