QML Quick Controls compile error

Thanks again sierdzio. Got an hint from someone else saying that QtQuick.Controls requires QtQuick 2.1 (also found that confirmed at the following link, http://doc-snapshot.qt-project.org/qt5-stable/qtquickcontrols/qtquickcontrols-index.html however currrently I use QtQuick 1.1 in my QML file. I didn’t test it yet, but this might be the problem.
