Indeed I misunderstood. These paths are generated by dub, so it's mostly
dub that has to be changed to use some environment variable.

LOCALAPPDATA is probably what you are looking for. Only if it is not
set, dub uses APPDATA.

There is also the option to "Add import paths of project dependencies"
which might help to remove most of the paths from the setting. That
option didn't exist when "dub generate" was implemented, though.
