This new version uses the Xboard command "ics" to infer if xadreco is connected to FICS (string "freechess.org") or if not, assumes it is "lichess.org".
If no ics
command appears at all, then it understands it is standalone.
Now there is no need to compile with two configurations.
$ make
is enough, for x_86
and arm
.
For windows:
$ make xadreco.exe
