[cmake-developers] Xcode generator is adding old attributes on .pbxproj

[Gregor Jasny]

Hello,

some time ago I started a project to make the CMake generated pbxproj
identical to the one Xcode writes. Some patches of that effort are
already in master, some lack some cleanup.

It would be great working with you on individual patches to 'modernize'
generated pbxproj files. Patches would be a superb start.

Note: you could use the xcproj tool to ask Xcode to re-generate the
project by running "xcproj touch".

I also intend to work on generating schema directly from CMake but this
will take some time.

Thanks,
Gregor
