Compilation error: pyversion( PyUnicode_FromString( PY_KIWI_VERSION ) )

[kiefernforst]

I've just wanted to updated from kiwi 1.4.7 to 1.5.0 with the same build recipe I've been using for years.

py/src/kiwisolver.cpp: In function 'bool {anonymous}::add_objects(PyObject*)':
py/src/kiwisolver.cpp:64:48: error: 'PY_KIWI_VERSION' was not declared in this scope; did you mean 'KIWI_VERSION'?
   64 |     cppy::ptr pyversion( PyUnicode_FromString( PY_KIWI_VERSION ) );
      |                                                ^~~~~~~~~~~~~~~
      |                                                KIWI_VERSION

I've fixed this by deleting all the version assertions.

henceforth from kiwisolver/__init__.py
kiwi_version,
version,

Any idea why e.g. https://gitlab.archlinux.org/archlinux/packaging/packages/python-cppy/-/raw/main/PKGBUILD?ref_type=heads stopped working?
