[cmake-developers] Drop support for older Xcode versions?

[Gregor Jasny]

Hello,

I'd like to get your feedback on deprecating or dropping support for
older Xcode versions. During changes on the Xcode generator it gets
harder and harder to test against old and very old Xcode versions like 3
and 4.

Are there still users around for these versions of Xcode?

PS: I'm talking here about the Xcode generator which creates Xcode
projects, not the Makefile or Ninja generator.

Thanks,
Gregor
