It looks reasonable at first glance. I'll give it a try with the full
CMake test suite tomorrow plus maybe a build of a larger project, and
let you know if I discover any gotchas.
Thanks,
David

Hi David,
Please see attached patch. It seems to work with the project I happened to
have open; it's not tested more then that. You know the xcode generator a
whole lot better then me; does it seem reasonable?
Thanks

Sounds like we need a ZERO_CHECK target like we have in the Visual
Studio generators to enable parallel building in Xcode.
There are currently some problems with the existing CMake re-run
commands on VS builds when CMake inputs change during the course of
the build. When that happens, (not something that us CMake devs
expect, by the way, but not forbidden/prevented either...), CMake
re-runs during the middle of the build, and we get all the bug reports
about Visual Studio reload stuff not working (here, and related
issues: http://public.kitware.com/Bug/view.php?id=11258 and
particularly, this note:
http://public.kitware.com/Bug/view.php?id=11440#c26905 )
I don't think there's a specific reason for it... Perhaps it was
simply easiest that way, or we didn't have a way to depend on custom
targets at the time, or it was modeled after the VS re-run rules...
(Or maybe Bill or Brad will chime in if I'm incorrect here...)
HTH,

Hi guys,
I noticed that each XCode target has an associated CMake ReRun script
phase. Is there a specific reason for this (in difference to having
one target that all others depend on that does the ReRun check?)
It causes a fair few issues, it fails when you are parallelcompiling
targets (It'll start number of cpus copies of cmake at the same
time), secondly it adds quite some time to the build if you have many
targets
