Yes, it's true, but now there's extra required beyond simply "installing Xcode".
Brad's partially addressed the problem here today, with this commit, now in 'next': http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=e88bae77c3388a5b474b081e572004f02772d162 However, in order to run on one of these new systems, and get a good command line build going, you probably have to do something like: xcrun bash cmake in the "Xcode environment" Ctrl+D to go back to the non-Xcode env So..... just like all the other makefile generators, you have a sane "build env" at CMake configure time. Using xcode-select should get us part way there, but now that we have this new world of command line tools separate from "installing Xcode", we do have to adapt to it somehow. Having these emails in the mailing list archive is at least a start to get people thinking in the right direction.
