Overrides the Controls style.
By default, Qt Quick Ultralite Controls use the default style. To use a custom style, you can set this target property to the import URI of the style you want to use. This is the most convenient way to switch between the styles without changing all the
statements in the QML source files.
注意： This property is applicable to executable targets only.
This property was introduced in Qt Quick Ultralite 1.0.
