[CMake] CMake 2.8.1 + Qt/Cocoa + OS X Problem -- qt_menu.nib not getting copied

[kent williams]

I'll include my CMakeLists.txt at the end of this message, but the
long and the short of it is this: My ApplicationBundle crashes when I
try and open it with this classic error message:

Qt internal error: qt_menu.nib could not be loaded. The .nib file
should be placed in QtGui.framework/Versions/Current/Resources/  or in
the resources directory of your application bundle.

This is supposed to be fixed, as documented in this bug:

http://public.kitware.com/Bug/view.php?id=10000

I checked out the latest GIT CMake and verified that the file in
question is the same in 2.8.1 and current GIT trunk.

So is there some magical extra step I need to get my bundle properly fixed up?
