Summary:                    Xcode generator's ReRunCMake.make fails if
dependencies have been deleted
Description: 
Currently, if a file that a CMake script previously had a dependency on is
deleted, the Xcode generator's ReRunCMake.make Makefile will fail with a "no
rule to make target <…>" error. This happens pretty frequently if you have a
CMake script that reads the ref file for your current git branch and you delete
branches regularly, and can also happen if you make other build system changes.

This can be solved by wrapping each item in the list with `$(wildcard <path>)`,
which effectively makes the dependencies optional.
