[yocto] Qt5.6 new modules

[idealsim]

Hi, we have build an image for udoo neo from meta-qt5 jansa/master-5.6 
and works fine (thanks to Christian Ege ). The problem is that I'm 
looking for https://github.com/qtproject/qtquickcontrols2 and 
https://github.com/qtproject/qtserialbus. My question is how we can add 
this modules to our build ?  I add this to our local.conf :

     "qtquickcontrols2 \
      qtserialbus \
     "
But this modules don't have buildable providers ! If someone can help to 
said me how to proceed ...

regards,

Mickael
