1529 \`configure' configures this package to adapt to many kinds of systems.

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

1553                           [PREFIX]
1554
1555 By default, \`make install' will install all the files in
1556 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1557 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1558 for instance \`--prefix=\$HOME'.

1775   CFLAGS      C compiler flags
1776   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1777               nonstandard directory <lib dir>
1778   LIBS        libraries to pass to the linker, e.g. -l<library>
1779   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1780               you have headers in a nonstandard directory <include dir>
1781   CXX         C++ compiler command
1782   CXXFLAGS    C++ compiler flags
1783   CXXCPP      C++ preprocessor
1784   CPP         C preprocessor
