How to contribute to a C++ project
Most projects use CMake (`cmake -B build && cmake --build build`). Match the compiler/standard version the README specifies.
- Get a clean build first — toolchain setup is the hardest part of C++ contributing.
- Keep memory safety in mind; reviewers scrutinise pointers and lifetimes.
- Documentation and build-script fixes are good ways to start.
