742Usage: $0 [OPTION]... [VAR=VALUE]...
743
744To assign environment variables (e.g., CC, CFLAGS...), specify them as
745VAR=VALUE.  See below for descriptions of some of the useful variables.
746
747Defaults for the options are specified in brackets.
748
749Configuration:
750  -h, --help              display this help and exit
751      --help=short        display options specific to this package
752      --help=recursive    display the short help of all the included packages
753  -V, --version           display version information and exit
754  -q, --quiet, --silent   do not print \`checking...' messages
755      --cache-file=FILE   cache test results in FILE [disabled]
756  -C, --config-cache      alias for \`--cache-file=config.cache'
757  -n, --no-create         do not create output files
758      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

763Installation directories:

766  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
767              [PREFIX]
768
769By default, \`make install' will install all the files in
770\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
771an installation prefix other than \`$ac_default_prefix' using \`--prefix',
772for instance \`--prefix=\$HOME'.
773
774For better control, use the options below.

778  --sbindir=DIR          system admin executables [EPREFIX/sbin]
779  --libexecdir=DIR       program executables [EPREFIX/libexec]

801  CXXFLAGS    C++ compiler flags
802  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
