Integrating C++ Code Generation Into a Large CMake Build
summary
Bloomberg uses an XSD-driven generator to emit C++ stubs and libraries and the talk shows how that generator integrates with CMake to avoid forcing teams to hand-edit generated code. It compares configure-time generation (runs during CMake configure so generated headers exist for static analysis) versus build-time add_custom_command, then describes a practical implementation that writes a small top-level project, runs generators in parallel via a deferred CMake build, emits depfiles, generates into a temp dir and only copies changed files — resulting in fast, correct incremental builds and workable rollouts across a large codebase.
