Whenever we change the name (or remove) generated cpp files with the `.gen.cpp` extension, users run into build issues when switching between branches (i.e. switching before and after the name change/removal). This is because we glob `*.cpp` so if a now-obsolete file from a previous build is present, we'll include it too, potentially leading to bugs or compilation failure (due to missing headers or invalid code). So globbing patterns in `add_source_files` will now skip files ending with `.gen.cpp`, which should instead be passed explicitly where they're used.
