Fix: Force building against Qt5 in PKGBUILD
requested to merge 469-feature-request-please-add-an-option-to-cmakelists-txt-to-force-a-specific-qt-version into stable
This change adds a CMake option OPENTODOLIST_QT_VERSIONS to the build, which can be used to select the order and/or specific Qt version to build against. We use this in the PKGBUILD to force building against Qt5, as currently, Qt6 lacks some modules that we strictly rely on.
Closes #469 (closed)
