Qt5.4.2/5.4/gcc_64/include/QtCore/qhash.h:201: error: 'QHashNode<Key, T>::key' has incomplete type  const Key key;
Qt5.4.2/5.4/gcc_64/include/QtCore/qglobal.h:648: error: forward declaration of 'const class QString'
 class QString;

The compiled environment is Qt5.4.2. So I add #include<QString> in the qmqtt_routedmessage.h file.

I test this library under Qt5.5，no error.
