Comment 1 Ralf Habacker 2024-04-01 11:17:53 UTC 
After an investigation, it turned out that the problem lies in the alkimia package, which generates a faulty LibAlkimia5Config.cmake
Comment 2 Ralf Habacker 2024-04-01 11:18:36 UTC 
Git commit 1a46fe803fab966bb3ed2ef280ecca0f1f8b5ef0 by Ralf Habacker.

cmake: Fix usage of Qt main version with Qt < 5.15

The error message on
https://build.opensuse.org/package/show/windows:mingw:win32/mingw32-kmymoney5
was 'Could not find a package configuration file provided by "QtCore"'.

According to
https://doc.qt.io/qt-6/cmake-qt5-and-qt6-compatibility.html#supporting-older-qt-5-versions
there is a variable QT_VERSION_MAJOR, not QT_MAJOR_VERSION, which is set
with a call to find_package(QT ...).
