I consider CMake 3.4 to be the broken state. The patch reverted in that 
topic removed the use of a documented command line option and added the use 
of an undocumented command line option.

I don't see any reason to add maintenance burden for long-obsolete Qt 
versions to new CMake versions. Maintenance burden in CMake is already far 
beyond reasonable :). Adding conditions which are not tested, and which must 
be maintained in future refactoring is the mistake.

That's up to you. I wanted to stick my pin in the map on this as the person 
who wrote the feature :).

Thanks,
