for raspberry pi compilation. This is because rppal won't compile on mac, so we only want to bring in the dependency when actually compiling for the raspberry pi, and so will manually need to enable the dependency.
Protobuf
This module contains the protobuf definitions used by PiCar.
Build
Run the gradle task
./gradlew generateProto
It's not recommended to run this alone, unless you plan on manually copying the generated files. The build.gradle files in the other projects will automatically copy the correct generated code across, which is recommended to use instead.
