CMake generators will make paths relative to the build tree (I think it
is to help reduce the generated output's size).

That sounds like a bug.

Please provide it :) .

Also, for the generation of the files, I don't think cuda would actually
need to be there (`ln -s /usr/bin/true ~/bin/cuda` should get you at
least that far).
