Hi nia,

that was a hint, not a solution (is not a patch...). I think that
you need to add code to detect tinfo on systems with split ncurses.
Maybe here?:  mk/curses.builtin.mk

I suppose the buildlink3 framework is not showing tinfo to cmake's
configuration process .

If that's the case you (the developers) need to have a conversation
on the best way to approach the problem (just test for the existence
of the lib and add it?).

Regards,
adr.
