[yocto] Can't get *.a's into SDK sysroot

Your answer remains me of this story:

Well... ;-)

I'll try to do some more testings, and to find out what is really wrong here.

The useful info is that out of clean tree nothing is visible in
${TMPDIR}/work, so, after all, might be that YOCTO build system does
not see my layer (for some unknown reason) at all.

Thank you,
Zoran
