Build

Proto files are taken from Chromium Open Screen GitHub mirror.

By default cargo build won't try to generate Rust code from the files located at protobuf/*, if you want to do that use GENERATE_PROTO environment variable during build and make sure you have protoc binary in $PATH:

$ GENERATE_PROTO=true cargo build
