1525 \`configure' configures this package to adapt to many kinds of systems.

1527 Usage: $0 [OPTION]... [VAR=VALUE]...
1528
1529 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1530 VAR=VALUE.  See below for descriptions of some of the useful variables.
1531
1532 Defaults for the options are specified in brackets.
1533
1534 Configuration:
1535   -h, --help              display this help and exit
1536       --help=short        display options specific to this package
1537       --help=recursive    display the short help of all the included packages
1538   -V, --version           display version information and exit
1539   -q, --quiet, --silent   do not print \`checking...' messages
1540       --cache-file=FILE   cache test results in FILE [disabled]
1541   -C, --config-cache      alias for \`--cache-file=config.cache'
1542   -n, --no-create         do not create output files
1543       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1544
1545 Installation directories:
1546   --prefix=PREFIX         install architecture-independent files in PREFIX
1547                           [$ac_default_prefix]
1548   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1549                           [PREFIX]
1550
1551 By default, \`make install' will install all the files in
1552 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1553 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1554 for instance \`--prefix=\$HOME'.

1771   CFLAGS      C compiler flags
1772   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1773               nonstandard directory <lib dir>
1774   LIBS        libraries to pass to the linker, e.g. -l<library>
1775   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1776               you have headers in a nonstandard directory <include dir>
1777   CXX         C++ compiler command
1778   CXXFLAGS    C++ compiler flags
1779   CXXCPP      C++ preprocessor
1780   CPP         C preprocessor
