1257 \`configure' configures this package to adapt to many kinds of systems.
1258
1259 Usage: $0 [OPTION]... [VAR=VALUE]...
1260
1261 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1262 VAR=VALUE.  See below for descriptions of some of the useful variables.
1263
1264 Defaults for the options are specified in brackets.
1265
1266 Configuration:
1267   -h, --help              display this help and exit
1268       --help=short        display options specific to this package
1269       --help=recursive    display the short help of all the included packages
1270   -V, --version           display version information and exit
1271   -q, --quiet, --silent   do not print \`checking ...' messages
1272       --cache-file=FILE   cache test results in FILE [disabled]
1273   -C, --config-cache      alias for \`--cache-file=config.cache'
1274   -n, --no-create         do not create output files
1275       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1276
1277 Installation directories:
1278   --prefix=PREFIX         install architecture-independent files in PREFIX
1279                           [$ac_default_prefix]
1280   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1281                           [PREFIX]
1282
1283 By default, \`make install' will install all the files in
1284 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1285 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1286 for instance \`--prefix=\$HOME'.
1287
1288 For better control, use the options below.

1340 Optional Packages:
1341   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1342   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1343   --with-gcc-major-version-only
1344                           use only GCC major number in filesystem paths
1345
1346 Some influential environment variables:
1347   CXX         C++ compiler command
1348   CXXFLAGS    C++ compiler flags
1349   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1350               nonstandard directory <lib dir>
1351   LIBS        libraries to pass to the linker, e.g. -l<library>
1352   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1353               you have headers in a nonstandard directory <include dir>
1354   CXXCPP      C++ preprocessor
1355
1356 Use these variables to override the choices made by `configure' or to help
1357 it to find libraries and programs with nonstandard names/locations.
