1202 \`configure' configures this package to adapt to many kinds of systems.
1203
1204 Usage: $0 [OPTION]... [VAR=VALUE]...
1205
1206 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1207 VAR=VALUE.  See below for descriptions of some of the useful variables.
1208
1209 Defaults for the options are specified in brackets.
1210
1211 Configuration:
1212   -h, --help              display this help and exit
1213       --help=short        display options specific to this package
1214       --help=recursive    display the short help of all the included packages
1215   -V, --version           display version information and exit
1216   -q, --quiet, --silent   do not print \`checking ...' messages
1217       --cache-file=FILE   cache test results in FILE [disabled]
1218   -C, --config-cache      alias for \`--cache-file=config.cache'
1219   -n, --no-create         do not create output files
1220       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1221
1222 Installation directories:
1223   --prefix=PREFIX         install architecture-independent files in PREFIX
1224                           [$ac_default_prefix]
1225   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1226                           [PREFIX]
1227
1228 By default, \`make install' will install all the files in
1229 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1230 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1231 for instance \`--prefix=\$HOME'.
1232
1233 For better control, use the options below.

1235 Fine tuning of the installation directories:
1236   --bindir=DIR            user executables [EPREFIX/bin]
1237   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1265 Optional Features:
1266   --disable-option-checking  ignore unrecognized --enable/--with options
1267   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
1268   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
1269   --enable-sim-hardware=LIST
1270                           Specify the hardware to be included in the build.
1271
1272 Some influential environment variables:
1273   CC          C compiler command
1274   CFLAGS      C compiler flags
1275   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1276               nonstandard directory <lib dir>
1277   LIBS        libraries to pass to the linker, e.g. -l<library>
1278   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1279               you have headers in a nonstandard directory <include dir>
1280   CPP         C preprocessor
1281
1282 Use these variables to override the choices made by `configure' or to help
1283 it to find libraries and programs with nonstandard names/locations.
