macOS
Windows

- Qt 6.0 for Android doesn't support multi-abi builds, it will be added in the next release (QTBUG-88841).
- When using CMake properties like QT_ANDROID_PACKAGE_SOURCE_DIR, qt_android_generate_deployment_settings(target_name) must be added after setting properties to make sure they are included in the deployment JSON file (QTBUG-88840).
iOS
- Using CMake to build user projects requires manual tweak. Please use qmake for now.
- Qt Creator cannot yet build iOS CMake projects (QTCREATORBUG-25058).
