The building of kcalc stops because "kwayland from kf6-workspace-modules" asks for Qt 6.7, but kde-builder builds Qt 6.6

Dear kde-builder people,

The building of kcalc stops because "kwayland from kf6-workspace-modules" asks for Qt 6.7, but kde-builder builds Qt 6.6:

In ~/kde/log/2024-08-02_04/kwayland/cmake.log we can see:

    CMake Error at CMakeLists.txt:45 (find_package):
    Could not find a configuration file for package "Qt6Gui" that is compatible
    with requested version "6.7.0".

    The following configuration files were considered but not accepted:

        /home/user/kde/qt/lib/cmake/Qt6Gui/Qt6GuiConfig.cmake, version: 6.6.3

        /lib/x86_64-linux-gnu/cmake/Qt6Gui/Qt6GuiConfig.cmake, version: 6.4.2
