1622 Usage: $0 [OPTION]... [VAR=VALUE]...
1623
1624 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1625 VAR=VALUE.  See below for descriptions of some of the useful variables.
1626
1627 Defaults for the options are specified in brackets.
1628
1629 Configuration:
1630   -h, --help              display this help and exit
1631       --help=short        display options specific to this package
1632       --help=recursive    display the short help of all the included packages
1633   -V, --version           display version information and exit
1634   -q, --quiet, --silent   do not print \`checking ...' messages
1635       --cache-file=FILE   cache test results in FILE [disabled]
1636   -C, --config-cache      alias for \`--cache-file=config.cache'
1637   -n, --no-create         do not create output files
1638       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1639
1640 Installation directories:
1641   --prefix=PREFIX         install architecture-independent files in PREFIX
1642                           [$ac_default_prefix]
1643   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1644                           [PREFIX]
1645
1646 By default, \`make install' will install all the files in
1647 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1648 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1649 for instance \`--prefix=\$HOME'.
1650
1651 For better control, use the options below.

1933   LIBS        libraries to pass to the linker, e.g. -l<library>
1934   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1935               you have headers in a nonstandard directory <include dir>
1936   CXX         C++ compiler command
1937   CXXFLAGS    C++ compiler flags
1938   CXXCPP      C++ preprocessor
