No need for := here, a simple = should suffice?

Why not put the sources in:
meta-mylayer/recipes-test/test/my-test-0.1/src/
meta-mylayer/recipes-test/test/my-test_0.1.bb
and have SRC_URI = "file://src/" without needing to add
FILESEXTRAPATHS_prepend := "${THISDIR}:" so that it follows what almost
every recipe does?
S will be as you wrote above.
I thought you were trying to find an example with externalsrc for our
docs, but it seems you have a different thing in mind, can you tell us
so we are able to help you with your actual issue/question :) ?
Cheers,
Quentin
