1426 \`configure' configures package-unused version-unused to adapt to many kinds of systems.
1427
1428 Usage: $0 [OPTION]... [VAR=VALUE]...
1429
1430 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1431 VAR=VALUE.  See below for descriptions of some of the useful variables.
1432
1433 Defaults for the options are specified in brackets.
1434
1435 Configuration:
1436   -h, --help              display this help and exit
1437       --help=short        display options specific to this package
1438       --help=recursive    display the short help of all the included packages
1439   -V, --version           display version information and exit
1440   -q, --quiet, --silent   do not print \`checking...' messages
1441       --cache-file=FILE   cache test results in FILE [disabled]
1442   -C, --config-cache      alias for \`--cache-file=config.cache'
1443   -n, --no-create         do not create output files
1444       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1445
1446 Installation directories:
1447   --prefix=PREFIX         install architecture-independent files in PREFIX
1448                           [$ac_default_prefix]
1449   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1450                           [PREFIX]
1451
1452 By default, \`make install' will install all the files in
1453 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1454 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1455 for instance \`--prefix=\$HOME'.
1456
1457 For better control, use the options below.

1460   --bindir=DIR            user executables [EPREFIX/bin]

1583   LIBS        libraries to pass to the linker, e.g. -l<library>
1584   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1585               you have headers in a nonstandard directory <include dir>

1587   CXXFLAGS    C++ compiler flags
1588   CPP         C preprocessor

1593 Use these variables to override the choices made by `configure' or to help
1594 it to find libraries and programs with nonstandard names/locations.
