1392
1393 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1394 VAR=VALUE.  See below for descriptions of some of the useful variables.
1395
1396 Defaults for the options are specified in brackets.
1397
1398 Configuration:
1399   -h, --help              display this help and exit
1400       --help=short        display options specific to this package
1401       --help=recursive    display the short help of all the included packages
1402   -V, --version           display version information and exit
1403   -q, --quiet, --silent   do not print 'checking ...' messages
1404       --cache-file=FILE   cache test results in FILE [disabled]
1405   -C, --config-cache      alias for '--cache-file=config.cache'
1406   -n, --no-create         do not create output files
1407       --srcdir=DIR        find the sources in DIR [configure dir or '..']

1415 By default, 'make install' will install all the files in
1416 '$ac_default_prefix/bin', '$ac_default_prefix/lib' etc.  You can specify
1417 an installation prefix other than '$ac_default_prefix' using '--prefix',
1418 for instance '--prefix=\$HOME'.
