1398 Installation directories:
1399   --prefix=PREFIX         install architecture-independent files in PREFIX
1400                           [$ac_default_prefix]
1401   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1402                           [PREFIX]
1403
1404 By default, \`make install' will install all the files in
1405 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1406 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1407 for instance \`--prefix=\$HOME'.

1499               nonstandard directory <lib dir>
1500   LIBS        libraries to pass to the linker, e.g. -l<library>
1501   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1502               you have headers in a nonstandard directory <include dir>
