I also think it would be good to point out the use of := in the

assignment and why it's important.
Knowing that the := operator will put your directories first is only
useful if you also know that the underlying mechanism will take the
first such files from the given directories it encounters :-) What's
to say bitbake doesn't look at all the directories/files and take the
last ones?
This has more to do with how the path is constructed (using _prepend).
My point, which was totally unclear to me when using this line, was
that with ':=' ${THISDIR} evaluates to the directory that contains
the .bbappend file (what you want/need) whereas with '=' it evaluates
to the directory containing the main .bb file. Incredibly confusing
if you miss it...
