no pyproject.toml, pip install at risk of being blocked

[emilezwiggelaar]

When installing this library using Python v3.13.3, pip v25.1.1 and setuptools v80.9.0 I get this warning:

DEPRECATION: Building 'robotframework-soaplibrary' using the legacy setup.py bdist_wheel mechanism, which will be removed in a future version. pip 25.3 will enforce this behaviour change. A possible replacement is to use the standardized build interface by setting the --use-pep517 option, (possibly combined with --no-build-isolation), or adding a pyproject.toml file to the source tree of 'robotframework-soaplibrary'. Discussion can be found at pypa/pip#6334

Command used:
pip install -U --force-reinstall --no-cache robotframework-soaplibrary

This is set to become a problem real soon, can anything be done?
