Something is odd here because if your foo library links to libmosquitto1.so.1 then it should already get a runtime dependency on the libmosquitto1 package without you needing to add it. I would perhaps suggest looking at pkgdata -  bitbake -e foo | grep PKGDATA_DIR  and then look in runtime/foo under that and see what RDEPENDS is indicated in there.

Cheers,
Paul
