1216 \`configure' configures this package to adapt to many kinds of systems.
1217
1218 Usage: $0 [OPTION]... [VAR=VALUE]...
1219
1220 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1221 VAR=VALUE.  See below for descriptions of some of the useful variables.
1222
1223 Defaults for the options are specified in brackets.
1224
1225 Configuration:
1226   -h, --help              display this help and exit
1227       --help=short        display options specific to this package
1228       --help=recursive    display the short help of all the included packages
1229   -V, --version           display version information and exit
1230   -q, --quiet, --silent   do not print \`checking ...' messages
1231       --cache-file=FILE   cache test results in FILE [disabled]
1232   -C, --config-cache      alias for \`--cache-file=config.cache'
1233   -n, --no-create         do not create output files
1234       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1235
1236 Installation directories:
1237   --prefix=PREFIX         install architecture-independent files in PREFIX
1238                           [$ac_default_prefix]
1239   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1240                           [PREFIX]
1241
1242 By default, \`make install' will install all the files in
1243 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1244 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1245 for instance \`--prefix=\$HOME'.
1246
1247 For better control, use the options below.

1249 Fine tuning of the installation directories:
1250   --bindir=DIR            user executables [EPREFIX/bin]

1278 System types:

1290   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1291   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1292   --with-windows-headers=DIR
1293                           specify where the windows includes are located
1294   --with-windows-libs=DIR specify where the windows libraries are located
1295
1296 Some influential environment variables:
1297   CC          C compiler command
1298   CFLAGS      C compiler flags
1299   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1300               nonstandard directory <lib dir>
1301   LIBS        libraries to pass to the linker, e.g. -l<library>
1302   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1303               you have headers in a nonstandard directory <include dir>
1304   CXX         C++ compiler command
1305   CXXFLAGS    C++ compiler flags
1306
1307 Use these variables to override the choices made by `configure' or to help
1308 it to find libraries and programs with nonstandard names/locations.
