Dear Debian Packager

I am the upstream developer of a few debian packages (fabio, pyfai...) and
those packages used to rely on numpy.distutils. Since setuptools 60,
this is not more possible so I changed the build system to use mesonpy
(pep517 compliant).

I found it easy to tell the debian packaging helper pybuild to use the `pyproject.toml` file to build the software instead of the `setup.py`:
`export PYBUILD_SYSTEM=pyproject` in the debian/rules file.

But later on, the meson configuration finds cython as cython3 but complains the compiler was not found:

```
dh build --with python3,sphinxdoc --buildsystem=pybuild
   dh_update_autotools_config -O--buildsystem=pybuild
   dh_autoreconf -O--buildsystem=pybuild
   dh_auto_configure -O--buildsystem=pybuild
	pybuild --configure -i python{version} -p 3.11
   dh_auto_build -O--buildsystem=pybuild
	pybuild --build -i python{version} -p 3.11

```

I had a similar problem for python3 and it was solved by installing `python-is-python3`. But there is no such trick for cython ...

Nota: `sudo ln -s /usr/bin/cython3 /usr/bin/cython` addresses the bug but I am looking for a solution which is compliant with debian packaging !

Thanks for your help.

Jerome
