# OrcaSlicer Config Codegen CMake Module
#
# Generates C++ source files from protobuf schema definitions.
# Generated files are checked into the repo so builds work without protoc.
# Generated files live in src/slic3r/GUI/generated/ and are gitignored.
# Run 'python tools/run_codegen.py' (requires grpcio-tools or protoc) to regenerate.
#
# Targets:
# codegen_config - Custom target to regenerate C++ from .proto files
