There is, it's cmake property LOCATION on the Qt5::qmake target.
So if that isn't used that'd be a bug and QT_SELECT would only workaround it.

In particular in ECM we have ECMQueryQmake which is meant to help with
querying path variables out of qmake. That bugger is using the
LOCATION property unless the target is missing altogether.

So yeah, figuring out where qmake is called from PATH and fixing that
to use Qt5::qmake LOCATION would be best here.
