Hello,
I have practically the same problem with OS X 10.7.4 and the last
version of XCode (4.4.1).
$> cmake -GXcode .

It fails with the following output:

After I upgraded to OS X 10.8, I recently upgraded my CMake version to
2.8.8.
I can build CMake projects if I use "Unix Makefiles" as a generator,
but if I use the Xcode generator, I get the following error:
The C compiler identification is GNU 4.2.1
The CXX compiler identification is GNU 4.2.1
Checking whether C compiler has -isysroot

(MESSAGE):

-buildstyle Development
xcodebuild: error: option '-buildstyle' is no longer supported
I understand that this error is associated with earlier versions of
Cmake that are incompatible with Xcode 4.4. I have tried removing all
traces of CMake 2.8.8 that I can from my system and re-installing, but
I cannot get rid of this error. I would be grateful for suggestions
of what to try next.
Thanks,
