I see. Another if construct, or a check_ncurses script which looks for
ncurses5-config or ncurses-config. After some digging in old SuSE
releases, ncurses5-config appeared in 11.0 (2008), SLES10 does not have
it yes . So blindly relying on -config scripts will likely break
building on old distributions.

This should work:

if ! ncurses5-config --libs 2>/dev/null;then if ! ncurses-config --libs ; then echo '-lncurses' ; fi ; fi
