Comment (by rjvbertin@…):

 BTW, it'd be nice if during testing some of you could also check the Xcode
 generator. For me it's proven to be useless in the sense that whenever for
 a more complex project I'd have loved to have a proper Xcode project,
 cmake generated corrupt projects.
 I reported that upstream, but was told 1) to try with the latest version
 (logical) and 2) to come up with a simpler testcase than a KDE application
 (can't remember which one reported). That latter point is a bit ...
 challenging :)
