[CMake] fixup_bundle placing libs under wrong directory

[Utkarsh Ayachit]

When I use fixup_bundle as follows, I end up with all the dependent
dylibs under "App/.../MacOS" instead of "App/.../Libraries". How do I
make fixup_bundle copy the dependencies into the Libraries dir and fix
paths accordingly?

fixup_bundle(\"${install_location}/Applications/paraview.app\" \"\"
\"${install_location}/lib\")
