[CMake] Xcode application bundle major issues

[Joshua Jensen]

Upon using CMake with Xcode and instructing CMake to generate 
application bundles, I've run into the following issues:

* When I make a change to a static library, the executable doesn't 
relink.  I have to rm it from the application bundle myself.  Upon 
digging through the (very verbose) build logs, I came across this little 
snippet during the XCODE_DEPEND_HELPER phase:

/bin/rm -f /Users/joshua/MiniApp/build/image/Debug/MiniApp

This is wrong.  It should be:

/bin/rm -f 
/Users/joshua/MiniApp/build/image/Debug/MiniApp.app/Contents/MacOS/MiniApp

I'm not immediately sure how to fix this, but it is a critical 
nuisance.  Code changes to libraries do not make it into the executable.

* The second issue has to do with running a Clean (an attempt to figure 
out what was going on).  Cleaning an application bundle project whacks 
the entire MiniApp.app/ folder structure.  Ack!  Any resources I had 
manually copied in there are destroyed.  CMake should not kill anything 
it does not write into that folder structure.
    
Anyway, I'd love solutions to both of these, but the executable not 
relinking is a huge deal.  I'll look into a solution in the meantime.  
If anyone knows how to fix this, please let me know.

Thanks.
