2027
2028 By default, \`make install' will install all the files in
2029 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2030 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2031 for instance \`--prefix=\$HOME'.
2032
2033 For better control, use the options below.

2077   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
2078   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
2079   --enable-maintainer-mode  enable make rules and dependencies not useful

2082   --disable-dependency-tracking  speeds up one-time build
2083   --enable-dependency-tracking   do not reject slow dependency extractors

2085 Some influential environment variables:
2086   CC          C compiler command
2087   CFLAGS      C compiler flags
2088   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
2089               nonstandard directory <lib dir>
2090   LIBS        libraries to pass to the linker, e.g. -l<library>
2091   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
2092               you have headers in a nonstandard directory <include dir>
2093   CPP         C preprocessor
2094
2095 Use these variables to override the choices made by `configure' or to help
2096 it to find libraries and programs with nonstandard names/locations.
