GPU code

I have to say my favorite, at least from these examples, is option 1. It does represent the code pretty well and it doesn't require an extra step (which is always painful). To give you an example why we don't want double-compile, let me just say two words: tolua + android.

Does it really require C++14, isn't C++11 enough? If this code takes a bit longer to develop, we might get C++11-ready in the meantime, but C++14 is too far out of reach.
