You shouldn't need hardibacker on cinder block. Hardibacker is used to provide a non flexible surface to attach ceramic tiles to. The cinder block is as rigid as the hardibacker. Hardibacker is needed on sheetrock or wood.

Thanks for asking a sensible question.
In the suggestions above there are some good ones, but heres my method if this is a non-insulated wall on the exterior.

a. Install 1-1/2" furing strips to the block.
b. Install a 3'4" to 1" rigid foam insulation like tuff R between the strips.
c. Lastly install the 3/4" cement board to the furring strips and seal it well.

Good Luck!

Your neighbors sound like mine, except they throw loud parties on their patio until about 3 am, so since I can't fall asleep at night, I mow the lawn at about 6 am. I figure I might as well use the time constructively. They don't seem to appreciate that I help keep the neighborhood property values higher. There's just no pleasin' some people.

We are tiling a shower right now, and we are tiling directly to the cinder walls. I also painted the walls with red guard beforehand, to prevent cracking and to make sure it is waterproof. We used thinset to set the tiles.

I have had success securing backer board to masonry by using thin set to the surface usually floors. You could always set firring strips to the block and then screw the boards up. I hope this helps.

You don't need it on a cinder block wall unless it is painted.
