Ability to add Qt Version without qmake

It would be great to be able to create a Kit with a Qt version compiled without qmake (-no-feature-qmake) as qmake is now superceded by cmake and is no longer required to work with Qt.

For trace, my current workaround is to edit $APPDATA/QtProject/qtcreator/qtversion.xml with:

<qtcreator>
<data>
<variable>QtVersion.0</variable>
<valuemap type="QVariantMap">
<value type="int" key="Id">3</value>
<value type="QString" key="QMakePath"><!!! My Qt InstallDir !!!>/bin/qmake.exe</value>
<value type="QString" key="QtVersion.Type">Qt4ProjectManager.QtVersion.Desktop</value>
<value type="QString" key="autodetectionSource"/>
<value type="bool" key="isAutodetected">false</value>
</valuemap>
</data>
<data>
<variable>Version</variable>
<value type="int">1</value>
</data>
</qtcreator>
