1259 \`configure' configures this package to adapt to many kinds of systems.

1261 Usage: $0 [OPTION]... [VAR=VALUE]...
1262
1263 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1264 VAR=VALUE.  See below for descriptions of some of the useful variables.
1265
1266 Defaults for the options are specified in brackets.
1267
1268 Configuration:
1269   -h, --help              display this help and exit
1270       --help=short        display options specific to this package
1271       --help=recursive    display the short help of all the included packages
1272   -V, --version           display version information and exit
1273   -q, --quiet, --silent   do not print \`checking ...' messages
1274       --cache-file=FILE   cache test results in FILE [disabled]
1275   -C, --config-cache      alias for \`--cache-file=config.cache'
1276   -n, --no-create         do not create output files
1277       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1278
1279 Installation directories:
1280   --prefix=PREFIX         install architecture-independent files in PREFIX
1281                           [$ac_default_prefix]
1282   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1283                           [PREFIX]
1284
1285 By default, \`make install' will install all the files in
1286 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1287 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1288 for instance \`--prefix=\$HOME'.
1289
1290 For better control, use the options below.

1343 Optional Packages:
1344   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1345   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1346   --with-gcc-major-version-only
1347                           use only GCC major number in filesystem paths
1348
1349 Some influential environment variables:
1350   CXX         C++ compiler command
1351   CXXFLAGS    C++ compiler flags
1352   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1353               nonstandard directory <lib dir>
1354   LIBS        libraries to pass to the linker, e.g. -l<library>
1355   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1356               you have headers in a nonstandard directory <include dir>
1357   CXXCPP      C++ preprocessor
1358
1359 Use these variables to override the choices made by `configure' or to help
1360 it to find libraries and programs with nonstandard names/locations.
