[cfe-dev] libtooling/libclang cannot find "__clang_cuda_runtime_wrapper.h"

[Artem Belevich via cfe-dev]

It would help a lot if you could figure out what compiler options we end up
using when the file is handled by libtooling or libclang. The fact that
you've got the error means that the file *is* treated as a CUDA file (good
news) but we either didn't add include path to clang headers, or the
headers are not where they should be.

I don't know if there's an easy way to do it libtooling or libclang. In the
past I dug these options out with debugger. You can try passing '-v' and
see if you get back the usual printout of header search path.
