1205 \`configure' configures Cygwin Documentation 0 to adapt to many kinds of systems.
1206
1207 Usage: $0 [OPTION]... [VAR=VALUE]...
1208
1209 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1210 VAR=VALUE.  See below for descriptions of some of the useful variables.
1211
1212 Defaults for the options are specified in brackets.
1213
1214 Configuration:
1215   -h, --help              display this help and exit
1216       --help=short        display options specific to this package
1217       --help=recursive    display the short help of all the included packages
1218   -V, --version           display version information and exit
1219   -q, --quiet, --silent   do not print \`checking ...' messages
1220       --cache-file=FILE   cache test results in FILE [disabled]
1221   -C, --config-cache      alias for \`--cache-file=config.cache'
1222   -n, --no-create         do not create output files
1223       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1224
1225 Installation directories:
1226   --prefix=PREFIX         install architecture-independent files in PREFIX
1227                           [$ac_default_prefix]
1228   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1229                           [PREFIX]
1230
1231 By default, \`make install' will install all the files in
1232 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1233 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1234 for instance \`--prefix=\$HOME'.
1235
1236 For better control, use the options below.

1279               nonstandard directory <lib dir>
1280   LIBS        libraries to pass to the linker, e.g. -l<library>
1281   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1282               you have headers in a nonstandard directory <include dir>
1283
1284 Use these variables to override the choices made by `configure' or to help
1285 it to find libraries and programs with nonstandard names/locations.
