Failed to build lightfm

```

Start by reproducing `pip install lightfm` on Python 3.12 and inspect the repository's `setup.py` and the generated extension sources under `lightfm/`, especially `lightfm/_lightfm_fast_openmp.c`. The work is done when LightFM builds and installs successfully on Python 3.12 without the reported setup or compilation errors.
