Qt creator code competion ignore build settings

The Qt creator code completion offer the cache property for Image qml element as seen on cache2.jpg.

• Help does not show anything about that property. (cache.jpg)
• Latest documentation won't guide either (latest.jpg)
• Git code do offer explanation that this is for Qt Quick 1.1
• Qt quick 1.1 supposed to be part of Qt 4.7.4, and the target is 4.7.3 (target.jpg)
• - - Expected that cache is not offered by completion if target is for example 4.6.3 or other targets releases without Qt quick 1.1
• C6-01 PR 1.2. does ship with Qt 4.7.3 and Qt Quick 1.0 (20090102_007.jpg)
• - - As a result a debug message about non-existing property is shown (cache.jpg)
• - - Installing of 4.7.3 Qt from the Qt SDK does not help since the bundle is Qt Quick 1.0 there.
