1201 \`configure' configures this package to adapt to many kinds of systems.
1202
1203 Usage: $0 [OPTION]... [VAR=VALUE]...
1204
1205 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1206 VAR=VALUE.  See below for descriptions of some of the useful variables.
1207
1208 Defaults for the options are specified in brackets.
1209
1210 Configuration:
1211   -h, --help              display this help and exit
1212       --help=short        display options specific to this package
1213       --help=recursive    display the short help of all the included packages
1214   -V, --version           display version information and exit
1215   -q, --quiet, --silent   do not print \`checking ...' messages
1216       --cache-file=FILE   cache test results in FILE [disabled]
1217   -C, --config-cache      alias for \`--cache-file=config.cache'
1218   -n, --no-create         do not create output files
1219       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1220
1221 Installation directories:
1222   --prefix=PREFIX         install architecture-independent files in PREFIX
1223                           [$ac_default_prefix]
1224   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1225                           [PREFIX]
1226
1227 By default, \`make install' will install all the files in
1228 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1229 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1230 for instance \`--prefix=\$HOME'.
1231
1232 For better control, use the options below.

1234 Fine tuning of the installation directories:
1235   --bindir=DIR            user executables [EPREFIX/bin]
1236   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1271 Some influential environment variables:
1272   PKG_CONFIG  path to pkg-config utility
1273   PKG_CONFIG_PATH
1274               directories to add to pkg-config's search path
1275   PKG_CONFIG_LIBDIR
1276               path overriding pkg-config's built-in search path
1277   SDL_CFLAGS  C compiler flags for SDL, overriding pkg-config
1278   SDL_LIBS    linker flags for SDL, overriding pkg-config
1279   CC          C compiler command
1280   CFLAGS      C compiler flags
1281   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1282               nonstandard directory <lib dir>
1283   LIBS        libraries to pass to the linker, e.g. -l<library>
1284   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1285               you have headers in a nonstandard directory <include dir>
1286
1287 Use these variables to override the choices made by `configure' or to help
1288 it to find libraries and programs with nonstandard names/locations.
