1562 \`configure' configures this package to adapt to many kinds of systems.

1564 Usage: $0 [OPTION]... [VAR=VALUE]...
1565
1566 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1567 VAR=VALUE.  See below for descriptions of some of the useful variables.
1568
1569 Defaults for the options are specified in brackets.
1570
1571 Configuration:
1572   -h, --help              display this help and exit
1573       --help=short        display options specific to this package
1574       --help=recursive    display the short help of all the included packages
1575   -V, --version           display version information and exit
1576   -q, --quiet, --silent   do not print \`checking ...' messages
1577       --cache-file=FILE   cache test results in FILE [disabled]
1578   -C, --config-cache      alias for \`--cache-file=config.cache'
1579   -n, --no-create         do not create output files
1580       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1581
1582 Installation directories:
1583   --prefix=PREFIX         install architecture-independent files in PREFIX
1584                           [$ac_default_prefix]
1585   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1586                           [PREFIX]
1587
1588 By default, \`make install' will install all the files in
1589 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1590 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1591 for instance \`--prefix=\$HOME'.

1819   LIBS        libraries to pass to the linker, e.g. -l<library>
1820   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1821               you have headers in a nonstandard directory <include dir>
1822   CXX         C++ compiler command
1823   CXXFLAGS    C++ compiler flags
1824   CXXCPP      C++ preprocessor
