Yes, this works.  However, this version of cdmatch has the (for me at
least) critical limitation that it doesn't handle subdirectories, just
the first one below the directory in $cdpath.  I've gone back to a
previous version of cdmatch and applied the same treatment, which
works there too, so the following is what I'm using at the moment.
Sorry, I can't remember who wrote this one originally.

The compctl instructions at the top of the other one still apply,
though I find it simpler to see if ordinary completion will find a
directory, and only then use cdmatch:

compctl -g '*(-/)' + -K cdmatch -S / -q cd pushd


###############################################################################
# cdmatch - directory matching for cd
#
# Save in your functions directory and autoload, then do
#   compctl -K cdmatch -S / -q + -g '*(D-/)' cd pushd
#
# Completes directories using cdpath (as cd does).  . is automatically
# included, because cd works that way.
#
# If an absolute path is being specified, or cdpath is blank, the completion is
# left up to the shell.  This results in such completions having a different
# look from those done by cdmatch itself.  Hopefully a future version of zsh
# will rectify this in some way.

local notonlydot npos args pref dir d

reply=()

# check for cdpath empty or only containing .
for dir in $cdpath; do [[ $dir != . ]] && notonlydot=1; done
if [[ $notonlydot != 1 ]]; then return; fi

# get word on which completion is requested
read -nc npos
read -Ac args

# check for absolute path - watch out for erroneous ~ expansion
pref=x$args[$npos]
if [[ $pref[2] = [/\~] ]]; then return; fi

# relative path - use cdpath
pref=$args[$npos]
for dir in . $cdpath; do
 for d in $dir/$pref*(ND-/:s,$dir/,,); do
  reply=( $reply ${d%%/#} )
 done
done
return
