dnl On macOS, there is no separate /usr/lib/libncursesw nor libpanelw.
dnl If we are here, we found a locally-supplied version of libncursesw.
dnl System-supplied ncurses combines libncurses/libpanel and supports wide
dnl characters, so we can use it like ncursesw.
dnl If a locally-supplied version of libncursesw is found, we will use that.
dnl There should also be a libpanelw.
dnl _XOPEN_SOURCE defines are usually excluded for macOS, but we need
dnl _XOPEN_SOURCE_EXTENDED here for ncurses wide char support.
