Repository Code style
It would be great to have clang-format for the repository:
Using https://code.qt.io/cgit/qt/qt5.git/tree/_clang-format from https://community.kde.org/Policies/Frameworks_Coding_Style note
or
With Frameworks 5.80 Extra-CMake-Modules contains a finalized clang-format configuration file with this coding style. https://raw.githubusercontent.com/KDE/extra-cmake-modules/master/kde-modules/clang-format.cmake
produces many changes to the files.
