1213 \`configure' configures this package to adapt to many kinds of systems.
1214
1215 Usage: $0 [OPTION]... [VAR=VALUE]...
1216
1217 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1218 VAR=VALUE.  See below for descriptions of some of the useful variables.
1219
1220 Defaults for the options are specified in brackets.
1221
1222 Configuration:
1223   -h, --help              display this help and exit
1224       --help=short        display options specific to this package
1225       --help=recursive    display the short help of all the included packages
1226   -V, --version           display version information and exit
1227   -q, --quiet, --silent   do not print \`checking ...' messages
1228       --cache-file=FILE   cache test results in FILE [disabled]
1229   -C, --config-cache      alias for \`--cache-file=config.cache'
1230   -n, --no-create         do not create output files
1231       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1232
1233 Installation directories:
1234   --prefix=PREFIX         install architecture-independent files in PREFIX
1235                           [$ac_default_prefix]
1236   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1237                           [PREFIX]
1238
1239 By default, \`make install' will install all the files in
1240 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1241 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1242 for instance \`--prefix=\$HOME'.
1243
1244 For better control, use the options below.

1246 Fine tuning of the installation directories:
1247   --bindir=DIR            user executables [EPREFIX/bin]
1248   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1289
1290 Some influential environment variables:
1291   CXX         C++ compiler command
1292   CXXFLAGS    C++ compiler flags
1293   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1294               nonstandard directory <lib dir>
1295   LIBS        libraries to pass to the linker, e.g. -l<library>
1296   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1297               you have headers in a nonstandard directory <include dir>
1298   CC          C compiler command
1299   CFLAGS      C compiler flags
1300
1301 Use these variables to override the choices made by `configure' or to help
1302 it to find libraries and programs with nonstandard names/locations.
