1220 \`configure' configures this package to adapt to many kinds of systems.
1221
1222 Usage: $0 [OPTION]... [VAR=VALUE]...
1223
1224 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1225 VAR=VALUE.  See below for descriptions of some of the useful variables.
1226
1227 Defaults for the options are specified in brackets.
1228
1229 Configuration:
1230   -h, --help              display this help and exit
1231       --help=short        display options specific to this package
1232       --help=recursive    display the short help of all the included packages
1233   -V, --version           display version information and exit
1234   -q, --quiet, --silent   do not print \`checking ...' messages
1235       --cache-file=FILE   cache test results in FILE [disabled]
1236   -C, --config-cache      alias for \`--cache-file=config.cache'
1237   -n, --no-create         do not create output files
1238       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1239
1240 Installation directories:
1241   --prefix=PREFIX         install architecture-independent files in PREFIX
1242                           [$ac_default_prefix]
1243   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1244                           [PREFIX]
1245
1246 By default, \`make install' will install all the files in
1247 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1248 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1249 for instance \`--prefix=\$HOME'.
1250
1251 For better control, use the options below.

1253 Fine tuning of the installation directories:
1254   --bindir=DIR            user executables [EPREFIX/bin]
1255   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1291   --with-windows-headers=DIR
1292                           specify where the windows includes are located
1293   --with-windows-libs=DIR specify where the windows libraries are located
1294
1295 Some influential environment variables:
1296   CC          C compiler command
1297   CFLAGS      C compiler flags
1298   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1299               nonstandard directory <lib dir>
1300   LIBS        libraries to pass to the linker, e.g. -l<library>
1301   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1302               you have headers in a nonstandard directory <include dir>
1303   CXX         C++ compiler command
1304   CXXFLAGS    C++ compiler flags
1305   CPP         C preprocessor
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.

1310 Report bugs to the package provider.
