A need for specifying CFLAGS et al isn't necessarily a bug or problem by
itself. We try to autodetect some common situations, that's all.

I take it you get a build but it fails at runtime? In what way does it fail?

Does the output of `ldd ../run/john` show a valid selection of opencl
and cuda libs from expected locations?
Does `../run/john --list=opencl-devices` or `../run/john
--list=cuda-devices` give any information?

I see nothing wrong in what you do. Are you using latest Jumbo from
GitHub? If not, you should definitely try that next.
