[PyQt] How to build pyqt sources to provide the same content than official wheel?

Ok, maybe unusable hasn't been a good word (sorry about my English btw),
what I meant is
the artifacts produced by nmake install are a very small subset from the
artifacts produced
by the official pypi wheel, compare both:

* Content produced by pyqt sources:

* Content produced by pypi wheel:

You can see there are a lot of missing submodules (pyd), also sip.pyd is
missing and basically the Qt folder also missing...
in addition, there are a lot of non-required sip files installed in the
virtual env.

So, is this because the way I've compiled pyqt from sources is not
complete? or is it because after installing pyqt from sources I'm also
required to do some extra manual steps...? What do you mean by "use your
existing Qt installation"? copying it manually to the virtualenv?

Actually, that's another question I'd like to ask you, what do you mean by
"fixed version of Qt is released"?
When developing pyqt, are you just using official packages from here
https://download.qt.io/archive/qt/
instead building yourself the Qt repos at some specific commit hash?

Wow, this sounds extremely awesome, really looking forward to it!

I must to say in the past years I've avoided building pyqt from sources
because I've always found it a
really complex non-standard python process, it's always looked to me like
the type of deployment
that works really way for the maintainer but not so well for the
users/customers. Said otherwise,
pyqt & sip are both amazing piece of technologies but the deployment
process looks to me like a bit obscure.
Which on the other hand, makes sense as the existing tools to create c++
wrappers packages have never been ideal.
I've got myself a bunch of custom tools to create swig wrapper that don't
follow the best python
packaging practices neither but they work "for me" :/
