1595 Usage: $0 [OPTION]... [VAR=VALUE]...
1596
1597 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1598 VAR=VALUE.  See below for descriptions of some of the useful variables.
1599
1600 Defaults for the options are specified in brackets.
1601
1602 Configuration:
1603   -h, --help              display this help and exit
1604       --help=short        display options specific to this package
1605       --help=recursive    display the short help of all the included packages
1606   -V, --version           display version information and exit
1607   -q, --quiet, --silent   do not print \`checking ...' messages
1608       --cache-file=FILE   cache test results in FILE [disabled]
1609   -C, --config-cache      alias for \`--cache-file=config.cache'
1610   -n, --no-create         do not create output files
1611       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1612
1613 Installation directories:
1614   --prefix=PREFIX         install architecture-independent files in PREFIX
1615                           [$ac_default_prefix]
1616   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1617                           [PREFIX]
1618
1619 By default, \`make install' will install all the files in
1620 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1621 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1622 for instance \`--prefix=\$HOME'.
1623
1624 For better control, use the options below.

1881               nonstandard directory <lib dir>
1882   LIBS        libraries to pass to the linker, e.g. -l<library>
1883   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1884               you have headers in a nonstandard directory <include dir>
1885   CXX         C++ compiler command
1886   CXXFLAGS    C++ compiler flags
1887   CXXCPP      C++ preprocessor
