fixup_bundle in BundleUtilities.cmake will do this for you. Unfortunately the functions are not documented in the header-comment, so you have to look into the file to read it. however, I remember there being problems with SDL which doesn't require fixing up since the install_name is already set for use as a private framework in a app bundle. Search the list archives, I'm pretty sure there was a solution.

Well, the actual error message would have been of help here, wouldn't it? And while you're at it, run with "make VERBOSE=1" in order to see the actual commands being run.

See my last remark.

See above.

WHAT did you try? Usually one has different build trees. One for release and the other for debug builds (or even more trees, depending on your needs). This also depends on whether you are using the Xcode generator or the Unix Makefiles generator (personally, I recommend the latter...). Besides, apart from size and build times, there's nothing that speaks against debugging a universal binary.

WHAT thread? You know, nobody here can see inside your head...

So, make will have to find them elsewhere or display an error. May be there is a way to find a version number ?

Don't get too fancy here. At most parse the version information from the headers (e.g. look at FindGTK2.cmake on how to do this).

What is ... here? Are you expecting help for something you don't even know about? ;-)
