kf6-kcoreaddons 6.28.0 requires ECM >= 6.28.0 but the vendored ECM source/ was still 6.10.0: the sync engine skipped it because ECM's version marker is a bare set(VERSION "X.Y.Z") that the parser didn't recognize (only KF_VERSION / PROJECT_VERSION / RELEASE_SERVICE_VERSION). Re-lay ECM from its 6.28.0 source.tar (pure cmake modules, no Redox port) and teach both the sync engine and the validator to read set(VERSION) so this class is caught, not silently skipped.

QtVersionOption
|
|
---------------
|
|
|
|
Adds a build option to select the major Qt version if necessary,
|
|
that is, if the major Qt version has not yet been determined otherwise
|
|
(e.g. by a corresponding ``find_package()`` call).
|
|
This module is typically included by other modules requiring knowledge
|
|
about the major Qt version.
|
|
|
|
If the ECM version passed to find_package was at least 5.240.0 Qt6 is picked by default.
|
|
Otherwise Qt5 is picked.
|
|
|
|
``QT_MAJOR_VERSION`` is defined to either be "5" or "6".
|
|
|
|
Since 5.82.0.
