[PATCH] D110596: [CUDA] Move CUDA SDK include path further down the include search path.

[Artem Belevich via Phabricator via cfe-commits]

tra requested review of this revision.
Herald added a project: clang.

This allows clang to work on Linux distributions like Debian where
<CUDA-PATH>/include may be a symlink to /usr/include. We only need
`cuda_wrappers` to be present before the standard C++ library headers.
The CUDA SDK headers themselves do not need to be found that early.

This addresses https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=995122
