1234
1235To assign environment variables (e.g., CC, CFLAGS...), specify them as
1236VAR=VALUE. See below for descriptions of some of the useful variables.
1237
1238Defaults for the options are specified in brackets.
1239
1240Configuration:
1241 -h, --help display this help and exit
1242 --help=short display options specific to this package
1243 --help=recursive display the short help of all the included packages

1257By default, \`make install' will install all the files in

1259an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1260for instance \`--prefix=\$HOME'.

81ecdfbb 1305 LIBS libraries to pass to the linker, e.g. -l<library>
d0ac1c44 1306 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
