-Subject: [PATCH] Fix: Installed Symlink LIB
-
-The latest patch to these routines broke our library alias in installs.
-
-By default, this variable is relative and needs the prefix appended.
-In some cases, e.g., if externally set, it can already be absolute. In that
-case, we skip adding the prefix.
