SIP real library wrapping

[ZephOne]

Thanks for the answer.

Indeed, the top level .pro file is not the same.

The organisation of the project is like this:

.
├── build
│   └── sip.h
├── myeventfilters
│   ├── myeventfilters.cpp
│   ├── myeventfilters.h
│   └── myeventfilters.pro
├── Dockerfile
├── MANIFEST.in
├── project.py
├── pyproject.toml
├── README.md
├── setup.cfg
├── setup.py
└── sip
    └── customeventfilters.sip

When the build folder is generated containing the top level .pro file, the top level .pro file does not include as subdirs the folders rootproject/myeventfilters and then is missing myeventfilters (I think). With sip4, the subdirs rootproject/myeventfilters was included.
So I will try to modify it via the project.py file like it seems to be done with the project.py file in PyQt5.
