rpath

[Chila]

I'm creating a shared library that has QT elements, and the odd thing is that if I don't use the 'rpath' linker flag for pointing the location of the QT shared libraries, it emits this message:

QQmlApplicationEngine failed to load component 
qrc:/main.qml:1 module "QtQuick" version 2.4 is not installed

When I develop an executable, it doesn't do that, "-L" is sufficient and runs with no problem. I don't like rpath flag since if you deploy the executable elsewhere, you need the location to be the exact same. How can I avoid this?
