Windows compilation errorr E0432: unresolved import: 'zcash_client_backend::proto::service::compact_tx_streamer_server'

[AlwaysCompile]

Compilation works on linux. However, compilation is broken on windows with the above error. This occurs when compiling the zingo-testutils module.

Full error is E0432: unresolved import: 'zcash_client_backend::proto::service::compact_tx_streamer_server' triggered by the line compact_tx_streamer_server::{CompactTxStreamer, CompactTxStreamerServer}, in grpc_proxy.rs line 10.

It says "could not find 'compact_tx_streamer_server' in 'service'"

Rust is 1.7.6 both when attempted compilation for linux and for windows where the error occurs.

Any guidance so this can be utilized on windows?
