No, := is required whenever you use THISDIR in a bbappend, unless you
*really* mean the path to the recipe itself, which is unlikely. THISDIR
evaluates based on FILE, which resolves to the current file being parsed,
at the time it's expanded.
Bottom line, what you are trying to create is something that looks like
