It's not what you're building that's the problem, but the package you're 
selecting to go into the image. The "qt4-embedded" package will pull in all of 
the Qt/Embedded packages, which probably isn't what you want. Assuming your Qt 
application is compiled rather than pure QML, most of the time you can get 
away with only installing your Qt application - the Qt libraries that it uses 
will be installed automatically as dependencies. Then the only thing you will 
need to install as far as Qt is concerned are any plugins (database, image, 
etc.). You may also want qt4-embedded-qml-plugins and qt4-embedded-qmlviewer 
depending on how you start your application.

Cheers,
Paul
