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

2063 System types:

2075   --disable-option-checking  ignore unrecognized --enable/--with options
2076   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
2077   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
2078   --enable-maintainer-mode  enable make rules and dependencies not useful
2079                           (and sometimes confusing) to the casual installer
2080   --disable-dependency-tracking  speeds up one-time build

2082
2083 Some influential environment variables:
2084   CC          C compiler command
2085   CFLAGS      C compiler flags
2086   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
2087               nonstandard directory <lib dir>
2088   LIBS        libraries to pass to the linker, e.g. -l<library>
2089   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
2090               you have headers in a nonstandard directory <include dir>
2091   CPP         C preprocessor
2092
2093 Use these variables to override the choices made by `configure' or to help
2094 it to find libraries and programs with nonstandard names/locations.
