No - classes only exported with Q_AUTOTEST_EXPORT are not meant to be used this way. They are only exported at all in developer build so that autotests can use them. Deployed versions of Qt will not have these symbols exported.
Flickable is not public C++ API, only public QML API. To create a flickable extended QML component, you should use
Flickable{
//QML code goes here
}

Nice, but even if I build qt with -developer-build is it a correct and
reasonable way to create my flickable extended qml component ?
