[cmake-developers] fix-OSX-bundle-rpaths-and-Qt5 topic

[Adam Strzelecki]

Done. Tested with Qt5 & Qt4, pushed as f9fcea6803f636adfc9f5755d9c92c802cdc2fb6 to stage/fix-OSX-bundle-rpaths-and-Qt5 (last commit to this branch).

@Brad: Shall I make it as separate branch and merge for staging, or you can simply cherry-pick it?

    Ensure framework symlinks and Info.plist exist
    
    This restores Qt SDK 4.8 and >= 10.6.5 codesign compatibility improving
    embedding frameworks using correct bundle layout described at:
    
    https://developer.apple.com/library/mac/documentation/MacOSX/Conceptual/BPFrameworks/Concepts/FrameworkAnatomy.html
    
    1. If Versions/VERSION/Resources/Info.plist is missing, well known incorrect
       locations are checked for Info.plist and Info.plist is copied from there,
       otherwise codesign will fail.
    
    2. Root framework symlinks to binary and Resources are restored to point inside
       Versions/Current, otherwise Qt 4.8 looking for Resources/ in framework root
       will fail.
