Now the latest layout is like:

dlb
├── driver
│   └── dlb2
│       ├── user.h
└── libdlb
    ├── Makefile

I want to run make under libdlb dir and it depends on driver/dlb2/user.h.

I can not use filegroup() to include the user.h since it would make bazel cannot find Makefile.

I also tried to copy this header file into libdlb dir, but failed to find a way to do it.

@phlax is there a way to do it?

@phlax @adisuissa sorry that I add some local changes here :(

[daixiang0]

I try to move files into one dir by Bazel and fail, so I just move the file by patch.

LGTM, thanks!
I'll let @phlax have the final say.

i would have preferred we avoid the patch altogether - but this is definitely better than the previous iteration

lgtm, thanks @daixiang0
