Unable to compile w/ prost-codec, missing proto files in grpcio-sys directory?

[rdaum]

Fails in build.rs phase for grpcio-sys

Tried with both Rust 1.76.0 and 1.68.2:

(Trying to compile with no SSL implementation (intranet) if that means anything, but it seems to fail in the same way with with openssl as well.)

Dep:

grpcio = { version = "0.13.0", default-features = false, features = ["prost-codec"] }

Failure:

Looks like the cmake build is looking for these artifacts under e.g. grpc/test/core/tsi/alts/fake_handshaker/handshaker.proto

but in my directory they live at e.g. grpc/src/core/tsi/alts/handshaker/proto/handshaker.proto

and some aren't there at all (e.g. fuzzing_event_engine.proto)

[rdaum]

Building with a git = or path = dependency instead of version from crates.io works fine, so something odd about the published 0.13.0 or the grpc-sys crate maybe?

I can't reproduce the error on both MacOS and CentOS. Can you provide a minimal reproduce repo?
