version confusion

[pebbe]

The README.md has under requirements:

Qt 5.0.X or 5.1.X with the development files

But the examples use Qt modules that are not avalable in Qt 5.1.1
The examples require a newer version of Qt. What version of Qt do I actually need? What versions are supported?

The requirments also list qmetaobject_p.h and qmetaobjectbuilder_p.h. These are present in Qt 5.1.1, but with a warning that they may change or disappear in future versions of Qt.
