Catch up with changes in 'gen_lib_options()':

- change how we call it
  - added methods 'library_dir_option()', 'library_option()', and
    'find_library_file()' that it calls
Added 'force' flag; it's automatically "respected", because this class
  always rebuilds everything!  (Which it to say, "force=0" is not respected.)
