[CMake] OS X, embedding Frameworks and generator problems

[Werner Smekal]

For the SDL Framework it is sufficient to just copy it during the
installation process, e.g. I do

# copy SDL frameworks into app bundle for Mac OS X
if(APPLE)
	INSTALL(DIRECTORY /Users/smekal/Library/Frameworks/SDL.framework
					DESTINATION hex-a-hop.app/Contents/Frameworks)
	INSTALL(DIRECTORY /Users/smekal/Library/Frameworks/SDL_mixer.framework
					DESTINATION hex-a-hop.app/Contents/Frameworks)
	INSTALL(DIRECTORY /Users/smekal/Library/Frameworks/SDL_ttf.framework
					DESTINATION hex-a-hop.app/Contents/Frameworks)
endif(APPLE)

BundeUtilites won't work (as posted before), since the SDL libraries
already have "@executable/../Framework/..." as a reference (use otool -L
on the SDL library) and BundleUtilities then doesn't know where to find
the SDL library (since if the executable is linked to that library it
uses the reference found in the library). But you also don't need to
copy the SDL Framework if you just want to run the app on your
development machine, since if the library isn't found in the app it
looks in /Library and /Users/user/Library to find the framework. But if
you want to give the app to someone else, you need to just copy the SDL
framework in the right place - best done during the install step. This
is a special case, usually BundleUtilities does a perfect job.
