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