1583 \`configure' configures this package to adapt to many kinds of systems.

1585 Usage: $0 [OPTION]... [VAR=VALUE]...
1586
1587 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1588 VAR=VALUE.  See below for descriptions of some of the useful variables.
1589
1590 Defaults for the options are specified in brackets.
1591
1592 Configuration:
1593   -h, --help              display this help and exit
1594       --help=short        display options specific to this package
1595       --help=recursive    display the short help of all the included packages
1596   -V, --version           display version information and exit
1597   -q, --quiet, --silent   do not print \`checking ...' messages
1598       --cache-file=FILE   cache test results in FILE [disabled]
1599   -C, --config-cache      alias for \`--cache-file=config.cache'
1600   -n, --no-create         do not create output files
1601       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1602
1603 Installation directories:
1604   --prefix=PREFIX         install architecture-independent files in PREFIX
1605                           [$ac_default_prefix]
1606   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1607                           [PREFIX]
1608
1609 By default, \`make install' will install all the files in
1610 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1611 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1612 for instance \`--prefix=\$HOME'.
1613
1614 For better control, use the options below.

1858   CFLAGS      C compiler flags
1859   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1860               nonstandard directory <lib dir>
1861   LIBS        libraries to pass to the linker, e.g. -l<library>
1862   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1863               you have headers in a nonstandard directory <include dir>
1864   CXX         C++ compiler command
1865   CXXFLAGS    C++ compiler flags
1866   CXXCPP      C++ preprocessor
1867   CPP         C preprocessor
1868   GMPLIBS     How to link GMP
1869   GMPINC      How to find GMP include files
1870   ISLLIBS     How to link isl
