Is it possible to compile Qt-creator 2.5 with Qt5 with Designer enabled?

[pavko]

Hi - I compiled qt-creator 2.5 with qt 4.8, everything works well.
But if I try to do this with Qt5, I get known error

@Project WARNING:
Project WARNING: QmlDesigner plugin has been disabled.
Project WARNING: The plugin depends on private headers from QtDeclarative module.
Project WARNING: To enable it, pass 'QT_PRIVATE_HEADERS=$QTDIR/include' to qmake, where $QTDIR is the source directory of qt.@

So, I cannot get working Designer in qt-creator.

My build string is:

@qmake /home/pavko/Repo/qt-creator/qtcreator.pro -r -spec linux-g++ CONFIG+=release "QT_PRIVATE_HEADERS=/home/pavko/Repo/qt5/qtbase/include"@

Should it work or it is too early to try build qt-creator 2.5 with Qt5?
