Hi,
Just to let you know, I'm creating Mac OS X universal binaries for my Bullet
Physics samples using CMake without problems. No QT is used, just GLUT, so
it might be in the QT area.
I use CMake creating Xcode projectfiles, and then just flag i386+ppc in the
projectfile settings.

Thanks,

Having successfully got CMake to install my resources to where I wanted
them in the bundle (thanks Axel), I'm now struggling to get it to build
my universal binary properly. The instructions I found after much
Googling were to set the variable "CMAKE_OSX_ARCHITECTURES" to
"ppc;i386", which I did. It builds the object files, but at the linking
stage produces this output:

This (and a lot more) is repeated for the i386 architecture as well. In
other words, it's looking for the Qt library inside the Mac SDK, which
suggests that it's feeding the linker the wrong flags.
I enclose my CMakeLists.txt again (revised, obviously) in case anyone can
tell me what, if anything, I'm doing wrong, or whether it's a bug in
CMake.
