Comment (by quentinmit):

 It makes me sad that every port is going to have to change its build
 process as a result of changes in `protobuf3-cpp`. Is there any way for
 this configuration to automatically happen as a result of the dependency?
 e.g. via a `pkg-config` file or a `#pragma` in the protobuf headers?

 If not, the commit LGTM as a workaround.
