The grpcio package doesn't actually depend on protobuf. Only generated code
(i.e. _pb2.py and _pb2_grpc.py) have this dependency. Instead, you'll want
to build the protobuf wheel from the protobuf repository and use that
alongside an off-the-shelf grpcio wheel.
Also, to answer the obvious follow-up question: "Why do we have a vendored
protobuf directory in our repo at all then?". The grpcio-tools wheel *does
*build
in the libprotobuf native code to generate the aforementioned _pb2.py and
_pb2_grpc.py files.
