This is gio telling you where it will look for installed schemas, so
not expanding prefix would not make any sense. You should certainly
prepend $DESTDIR. But, since gsettings is using XDG_DATA_DIRS anyway,
we should probably scrap the variable altogether and just
use $DESTDIR$(prefix)/glib-2.0/schemas. It is then up to people to set
XDG_DATA_DIRS matching that prefix at runtime.
