1412 Configuration:
1413   -h, --help              display this help and exit
1414       --help=short        display options specific to this package
1415       --help=recursive    display the short help of all the included packages
1416   -V, --version           display version information and exit
1417   -q, --quiet, --silent   do not print \`checking...' messages
1418       --cache-file=FILE   cache test results in FILE [disabled]
1419   -C, --config-cache      alias for \`--cache-file=config.cache'
1420   -n, --no-create         do not create output files
1421       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1422
1423 Installation directories:
1424   --prefix=PREFIX         install architecture-independent files in PREFIX
1425                           [$ac_default_prefix]
1426   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1427                           [PREFIX]
1428
1429 By default, \`make install' will install all the files in
1430 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1431 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1432 for instance \`--prefix=\$HOME'.
1433
1434 For better control, use the options below.

1551   CC          C compiler command
1552   CFLAGS      C compiler flags
1553   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1554               nonstandard directory <lib dir>
1555   LIBS        libraries to pass to the linker, e.g. -l<library>
1556   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1557               you have headers in a nonstandard directory <include dir>
1558   CXX         C++ compiler command
1559   CXXFLAGS    C++ compiler flags
1560   CPP         C preprocessor
1561   CXXCPP      C++ preprocessor
1562   CXXFILT     Location of GNU c++filt. Defaults to the first GNU version of
1563               `c++filt', `gc++filt' on PATH.
1564
1565 Use these variables to override the choices made by `configure' or to help
1566 it to find libraries and programs with nonstandard names/locations.
