It's not clear if you want to create .debs for your distro (depending on <br>
the distro provided PyQt/Qt) or wheels (depending on the PyQt/Qt wheels <br>
from PyPI).<br>
<br>
Assuming the latter you (probably) need to install the targeted version <br>
of Qt using the on-line installer. The other PyQt projects (eg. <br>
PyQt6-NetworkAuth to take the smallest) are examples of what you want to <br>
do.<br>
