   Hi Adriaan,

          Suppose if you want to install the prebuilt-deb packages based on
the selection like below:
           SRC_URI:append = " ${@
'file://example-prebuilt_1.0.0-0_bullseye.deb' if
d.getVar('BASE_DISTRO_CODENAME') == 'bullseye' else
'file://example-prebuilt_1.0.0-0_all.deb' }"

The above changes not works with the present implementation, with the help
of expanding the SRC_URI variable we can able to get the right packages in
WORKDIR.

Thanks,
Srinu
