Build Qt using kdesrc-build tutorial - June 2022 - 92247cfa

All that I know about building the Qt5 library including Qt5 WebEngine using kdesrc-build.
Then I build a KDE project (kalgebra) using this version of Qt5.
This allows me to use more of the features of the Qt Creator IDE on that project. Debug with step into will show the content of the *.cpp source code files from the qt5 project, including qt5webengine. I can see the complete call stack. I can inspect the values of identifiers from the qt5 *.cpp source code files.
