Subject: [PATCH] CMake: Write symlinks to directories as files in archives
 (#12284)

Do not recurse through directory symlinks when adding files.

Recursing through directory symlinks will generate broken archives,
i.e., they will look something like this:
  foo -> bar/bar
  foo/Info <- Shouldn't be in archive.
  bar/bar
  bar/bar/Info
