1576 Usage: $0 [OPTION]... [VAR=VALUE]...
1577
1578 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1579 VAR=VALUE.  See below for descriptions of some of the useful variables.
1580
1581 Defaults for the options are specified in brackets.
1582
1583 Configuration:
1584   -h, --help              display this help and exit
1585       --help=short        display options specific to this package
1586       --help=recursive    display the short help of all the included packages
1587   -V, --version           display version information and exit
1588   -q, --quiet, --silent   do not print \`checking ...' messages
1589       --cache-file=FILE   cache test results in FILE [disabled]
1590   -C, --config-cache      alias for \`--cache-file=config.cache'
1591   -n, --no-create         do not create output files
1592       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1593
1594 Installation directories:
1595   --prefix=PREFIX         install architecture-independent files in PREFIX

1597   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1598                           [PREFIX]
1599
1600 By default, \`make install' will install all the files in
1601 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1602 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1603 for instance \`--prefix=\$HOME'.

1839               nonstandard directory <lib dir>
1840   LIBS        libraries to pass to the linker, e.g. -l<library>
1841   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1842               you have headers in a nonstandard directory <include dir>
