By the time the Xcode generator writes the path, there is no
distinction between add_executable being called from the
CMakeLists.txt directly or through the function.  If you
message() out the path inside your function just before
or after add_executable, that is the path the generator will
see.  I expect it is correct, and the generator or Xcode
does something funny....especially since it works in VS.
