Use other variables in Creator Kits Environment

[stephenju]

Is there a way to use other environment variables or define and use a new one when setting the environment of a kit as described here? http://doc.qt.io/qtcreator/creator-targets.html

I am trying to prepend PATH and LIB on Windows with relative paths from QTDIR. But QTDIR doesn't seem to be available here. I tried defining and using my own variable but it doesn't resolve for my PATH and LIB command there.

Also. The UI sorts my lines of environment commands alphabetically no matter how I arrange them. That renders this information useless: http://doc.qt.io/qtcreator/creator-build-settings.html#batch-editing
