Add a proto_lang_toolchain() for cc_proto_library
Bazel's built-in cc_proto_library rule uses a proto_lang_toolchain to learn how to invoke proto-compiler.
To use Bazel's cc_proto_library, add the following to your project's WORKSPACE file:
local_repository(
name = "com_google_protobuf_cc",
path = "/path/to/protobuf-distribution/"
)
diff --git a/BUILD b/BUILD
