Yes the meson files need to be changed whenever you add or remove python or cython files. Either run 'tools/update-meson.py' locally or apply the changes suggested in the above output manually.

You have to (pip)install `meson`. Not sure what's the sage-the-distro way of doing this (or why meson is not automatically installed in the venv).

Or, preferably, after https://github.com/sagemath/sage/pull/39262 you can just run `uv run tools/update-meson.py`.

Maybe it just needs ./sage -sh first?
