  You attach it ( screw or expanding foam ) to the outside brick course.

  set it back 25mm from the outside edge.

  You cover the cavity with dry lining ( plasterboard & plaster )

  You used to have a turn of bricks to bridge the gap but that is now out of the building regs as it was a heat loss.

  you need to fix aluminium tie straps to the the door frame leaving them long enough to fix to the concrete block wall which needs to be pre-drilled with a masonry drill bit !insert sufficient rawl plugs and screws making sure that the frame is perfectly level and plumb!depending on how high your door opening is 4 fixings on each vertical frame is sufficient!best of luck!
