here is my dir layout: a.proto depends on b.proto, so import b.proto in a.proto.

├── proto
│   ├── BUILD
│   ├── CMakeLists.txt
│   ├── a.proto
│   └── b.proto
├── src

bazel build got error:

proto/a.proto:5:1: Import "b.proto" was not found or had errors.

but cmake works fine. why should I add import proto/b.proto in a.proto, but just import b.proto?

@alexeagle, @thesayyn can you triage?

afaik every import statement has to be relative to the workspace root if you are not using strip_import_prefix so this works as intended.
