# ════════════════════════════════════════════════════════════════════════════
# GNU-free CMake build for ncurses 6.5 (FenrirOS)
#
# Self-contained: generates all headers and sources that the GNU Makefile
# would normally produce, then compiles and links everything.
#
# Prerequisite: run ./configure ONCE before cmake to emit ncurses_cfg.h,
# curses.head, MKterm.h.awk, ncurses_dll.h, and other configure outputs.
# configure is a POSIX-sh script — not GNU make.
#
# Builds:
#   libncursesw.a  — wide-character curses library (single unified lib)
#   libpanelw.a    — panel library
#   libformw.a     — form library
#   libmenuw.a     — menu library
#   tic, infocmp, tput, clear, tset/reset, toe, tabs
