[CMake] Dependencies in Xcode files

[Daniel Dunbar]

Hi Bill,

Thanks for the reply.

The uses I'm seeing aren't on external targets, they are for internal
libraries which are built during the build. Is this the same problem?

Also, do you know if anyone has filed a bug with Apple tracking this issue?
