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

[emilezwiggelaar]

Describe the bug
Building wheels for collected packages: robotframework-httpctrl
DEPRECATION: Building 'robotframework-httpctrl' 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-httpctrl'. Discussion can be found at pypa/pip#6334

To Reproduce
pip install --force-reinstall --no-cache robotframework-httpctrl

Desktop (please complete the following information):

• OS: Windows
• Python v3.13.3, pip v25.1.1 and setuptools v80.9.0

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

Thanks for reporting. I will take a look and will fix it, most probably in the end of August.

The issue addressed:

• Added pyproject.toml to support modern PEP 517/518 builds.
• Removed setup.py; old-style installs may not work.

Please let me know if there are any issues.
