Greetings, Fellow Developers,

thank you so much for your answers. 

I would like to build pyside2 by myself; I did know indeed that it was possible
to start using Pyside2 using the binaries. But I would like to follow the
instructions for getting to the Shiboken2 world of Python bindings...

Sure, this is what I got:


I hope you'll be able to get to this output.

Thank you for the explanation. Yes, I had read some things about it.
