  34 # The complete configure script for ncurses is the ncurses5-config (or similar
  35 # name, depending on the flavor, e.g., ncursesw5-config, ncurses6-config, etc).
  36 # That provides more information than pkg-config, and is the portable and
  37 # recommended solution.
  38 #
  39 # For each library, generate a ".pc" file which depends on the base ncurses
  40 # library, except that the tinfo library does not depend on ncurses.
