If dealing with a user perhaps. Developers shouldn't have that problem.

Then how about a compromise of major.minor.patch ?

That doesn't work for me because my qtbase prefix is where I install qtbase 
dev branch and other Qt repos (also dev branch), cmake (master, a topic or 
whatever version I need to test the Qt cmake files with), some KDE stuff and 
some KDAB stuff.

I have another prefix for qtbase stable branch testing/work, another for Qt 
4.8 etc.

Clearing one of those prefixes completely just to remove micro-versioned 
cmake installations is not practical, and I don't want to add another 
dimension to my prefix system just for cmake installations.

Thanks,

Steve.
