Summary: Generated Protobuf library has to be in CLANG_EXPORTS and should also be installed appropriately. The easiest way to do that is via CMake's add_clang_library. That unfortunately applies "one directory - one clang_(library|tool)" policy so .proto files should be in a separate directory and complicates the layout. This setup works both in shared and static libs mode.
