Yes. Create another variant under arm - for example release-mqueue and release-mq (or you can re-use "release" variant 
for one of them),
Switch to Advanced mode (at the bottom) and select specific variant at the top. In Linker tab add your libraries. Same 
for another configuration.
You have to repeat the same for x86. If you want both in debug you have to do same for debug variants.
