Liquid Nails makes a specific drywall adhesive.... which should work...as long as you think you'll NEVER have to remove that drywall for any reason. If this is a below grade wall.... do yourself a favor....don't glue drywall to the brick.
Yes go with captaint`s method. Half in. strips of plywood, if wall is irregular,shim to plum. You may need to nail until glue dries where shimmed. but if wall is nice and plum you can glue wall apply drywall use fat boy screws ( heavy course thread screws ) these are made to bite into concrete. But furring wall with plywood first probably way less grief! When using fat bot screws these will not countersink properly, so you`ll need to remove before taping.

Sure there are different glues made that allow you to glue drywall straight to a brick or concrete block wall. The one problem with brick is that they are sometimes uneven and getting the drywall to contact the brick wall evenly in all places is difficult and can lead to a wavy wall line. What I suggest is to glue furring strips, something like a 2x2 to the brick wall at 16 on center. Use a glue like Liquid Nails Heavy Duty. The best way is to use the quick set-up method. Simply run a bead of glue on the furring strip and place it on the wall where you intend to put it and push it firmly. Then pull it back off the wall and let the glue sit up for about 10 minutes. If you do this, after waiting 10 minutes, you can place it back on the wall and push it firmly in place, and you will not be able to pull it back off. I would also suggest, before gluing, to hold each strip on the wall where they will be going and check for a high spot that may be causing problems. You can always notch out the wood if you find a problem area. The other reason I would use the wood furring strips is that you can always use nails in the wall to hang things later on.
Dot and dab is good and should work well use a spirit level and rest your plaster board on timber spacers which can help with packing the board for a vertical edge and be removed later if you have a cement screed floor this should help to keep it away from any possible damp source your skirting should cover this small gap.
