+\important When building static QML applications, which is enforced on platforms like iOS,
+QML files are scanned to detect import dependencies. That way, all
+necessary plugins and resources are resolved at compile time.
+However, only explicit import statements are considered (those found at

+To support static builds, you therefore need to ensure that QML files
