QtplasmaC installation

I am planning to install QtplasmaC.

My computer has Linuxcnc gmoccapy 3.1.3.8 running. It is using Mesa 7i92+7i76.

I have gone through QtplasmaC manual; but not sure where to start. Should I install plasmaC first and then upgrade?

I had tried with Pnc config wizard, but no QrplasmaC option there. 

How to proceed??

You need to be running master branch (LinuxCNC 2.9) to use QtPlasmaC.
PnCconf in master branch does support QtPlasmaC.
