at bblayers.conf, does BBLAYERS include the above full path of
meta-openembedded/meta-qt4? also, try placing the meta-qt4 at the same
level of meta-openembeded, because these are two independent
repositories (and if you run git clean -fd at meta-openmebeded, you do
not remove meta-qt4 by mistake :) )

Though BBLAYERS. Include any layer you want and depending on the
priority, bitbake will deal with the corresponding metadata (bbappends, etc.)

basically the latter answer applies to this one.
