[CMake] Problems generating Xcode projects

[Carminati Federico]

Hello,
    I am trying to generate an Xcode project. I have

cmake 2.6
Xcode 3.0
Mac OS X 10.5.4

When I try to open the project with Xcode I have

Project /Users/fca/AliCmake/NewIO/xcode_dir/AliRoot.xcodeproj cannot  
be opened because the project file cannot be parsed.

Any hint? Best,
