torstenandCopilot d890b11c5f Qt6 Migration: LtsWidgets, BUILD_RTI Guards, externe Dependencies dokumentiert
- LtsWidgets Verzeichnis vollständig migriert (Qt5→Qt6)
- BUILD_RTI Guards für RTI-spezifische Module hinzugefügt
- Externe Dependencies in EXTERNAL_DEPS.md dokumentiert
- Qt6 API-Änderungen: QRegExp→QRegularExpression, enterEvent(QEnterEvent*)
- AutoUic-Fehler bei ui_requirement behoben (SKIP_AUTOUIC)
- Include-Pfade korrigiert (LtsElevation, LtsMultiMonitor, LtsUtilsCore)
- MOC-Fehler behoben (Q_INTERFACES entfernt wo nicht benötigt)
- CMakeLists.txt Anpassungen für Qt6 (PUBLIC statt INTERFACE)
