Do you know how?  (Because that knowledge will be needed when
implementing this.)

No, that would require Cuda .cu file support in Automake; sorry.

I'd love to have this, and there has been a patch for this, too
(and I think it was reasonably good), but again, the copyright
question could not be cleared up so we have to ignore the patch.

If you are willing to code up a patch for this, and to assign
copyright to the FSF, then be my guest.

Cheers,
Ralf
