Typically what is done is to install 1x3 or 1x4 furring strips to
the wall and then to attach the drywall to those. That also would
allow you to put some thin foam insulation in the spaces between
the furring strips.

Thanks.

Sorry, but I forgot to add that there is no room to do any kind of
build-out or to add furring strips, etc. Adding just the sheetrock
will already be pushing the limit a little due to doors, trim,
kitchen cabinets, etc. that are along or adjacent to the existing
wall.

So, my only option is to glue or otherwise attach sheetrock directly
to the existing wall.

If you feel that is your only option, what exactly are you asking?

Sound transmission works via a few different mechanisms, so the first
thing to do is to determine which direction the sound will be going,
and what acoustic frequency you are trying to reduce.

Homasote is a good and inexpensive acoustical treatment that is
readily available and easy to work with. Covering it with fabric or
heavy-bodied wallpaper would take care of the aesthetics.

Forgot all about homasote; good catch if you can only use 1 x for the
ferring.
