configure will search for an appropriate library; the default search order

"Hcurses ncurses curses termcap". Note that even though termcap is usually
searched first zsh tries to make features from curses available and if the

ncurses is a newer version of curses and tinfo is related to it.
The library ncursesw is a variant of ncurses that supports wide characters.
zsh attempts to use this to provide functions needed by the zsh/curses
module; depending on the configuration, the main shell may not require the
additional functions. As the integration of wide character support into
ncurses is continuing, it is possible that on some systems attempting to
use ncursesw may cause problems during building. If so, please report this
to the developers at zsh-workers@sunsite.dk and attempt to recompile with
--with-term-lib="tinfo termcap ncurses curses" (see below).
On some systems a suitable development package with a name such as
curses-devel or ncurses-devel needs to be installed before zsh can

You can tell configure which libraries to search by passing an
argument via --with-term-lib. This takes a space-separated list
of libraries to try as its argument, so the default is equivalent to
--with-term-lib="tinfo termcap ncurses curses". It replaces the
--with-term-lib="ncursesw tinfo termcap ncurses curses". It replaces the
old option --with-curses-terminfo, which altered the search order but
didn't allow an explicit search list to be passed.
