1559 \`configure' configures this package to adapt to many kinds of systems.

1561 Usage: $0 [OPTION]... [VAR=VALUE]...
1562
1563 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1564 VAR=VALUE.  See below for descriptions of some of the useful variables.
1565
1566 Defaults for the options are specified in brackets.
1567
1568 Configuration:
1569   -h, --help              display this help and exit
1570       --help=short        display options specific to this package
1571       --help=recursive    display the short help of all the included packages
1572   -V, --version           display version information and exit
1573   -q, --quiet, --silent   do not print \`checking ...' messages
1574       --cache-file=FILE   cache test results in FILE [disabled]
1575   -C, --config-cache      alias for \`--cache-file=config.cache'
1576   -n, --no-create         do not create output files
1577       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1578
1579 Installation directories:
1580   --prefix=PREFIX         install architecture-independent files in PREFIX
1581                           [$ac_default_prefix]
1582   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1583                           [PREFIX]
1584
1585 By default, \`make install' will install all the files in
1586 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1587 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1588 for instance \`--prefix=\$HOME'.

1803 Some influential environment variables:
1804   CC          C compiler command
1805   CFLAGS      C compiler flags
1806   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1807               nonstandard directory <lib dir>
1808   LIBS        libraries to pass to the linker, e.g. -l<library>
1809   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1810               you have headers in a nonstandard directory <include dir>
1811   CXX         C++ compiler command
1812   CXXFLAGS    C++ compiler flags
1813   CXXCPP      C++ preprocessor
1814   CPP         C preprocessor
