The PEP 517 compliant PyQt build system

Project description

What is PyQt-builder?

PyQt-builder is the PEP 517 compliant build system for PyQt and projects that extend PyQt. It extends the sip build system and uses Qt’s qmake to perform the actual compilation and installation of extension modules.

Projects that use PyQt-builder provide an appropriate pyproject.toml file and an optional script. Any PEP 517 compliant frontend, for example sip-install or pip can then be used to build and install the project.
