QML Module Error: Running Qt Application on Embedded Linux

I am trying to run my cross compiled Qt GUI application on a specific TI board. I am using this command to start my application:

QT_DEBUG_PLUGINS=1 QT_PLUGIN_PATH=/root/qt-5.2.1-install/plugins LD_LIBRARY_PATH=/root/qt-5.2.1-install/lib/ ./simple_qml_ui -platform linuxfb

Unfortunately, an error occurs:

QFactoryLoader::QFactoryLoader() checking directory path "/root/qt_app/styles" ... 
QFactoryLoader::QFactoryLoader() checking directory path "/root/qt-5.2.1-install/plugins/styles" ... 
QQmlApplicationEngine failed to load component

qrc:/main.qml:4 module "QtQuick.Dialogs" is not installed

Am I missing an important deployment step? How to fix it?

It turns out that you just need to copy the plugins directory from your Qt installation folder to your application folder.
