1409       --help=recursive    display the short help of all the included packages
1410   -V, --version           display version information and exit
1411   -q, --quiet, --silent   do not print \`checking...' messages
1412       --cache-file=FILE   cache test results in FILE [disabled]
1413   -C, --config-cache      alias for \`--cache-file=config.cache'
1414   -n, --no-create         do not create output files

1417 Installation directories:
1418   --prefix=PREFIX         install architecture-independent files in PREFIX
1419                           [$ac_default_prefix]
1420   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1421                           [PREFIX]
1422
1423 By default, \`make install' will install all the files in
1424 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1425 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1426 for instance \`--prefix=\$HOME'.

1546   CFLAGS      C compiler flags
1547   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1548               nonstandard directory <lib dir>
1549   LIBS        libraries to pass to the linker, e.g. -l<library>
1550   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1551               you have headers in a nonstandard directory <include dir>
1552   CXX         C++ compiler command
1553   CXXFLAGS    C++ compiler flags
1554   CPP         C preprocessor
1555   CXXCPP      C++ preprocessor
1556
1557 Use these variables to override the choices made by `configure' or to help
1558 it to find libraries and programs with nonstandard names/locations.
