2025   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2026                           [PREFIX]
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.

2035 Fine tuning of the installation directories:

2064 System types:

2077   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
2078   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]

2081   --disable-dependency-tracking  speeds up one-time build

2084 Some influential environment variables:
2085   CC          C compiler command
2086   CFLAGS      C compiler flags
2087   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
2088               nonstandard directory <lib dir>
2089   LIBS        libraries to pass to the linker, e.g. -l<library>
2090   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
2091               you have headers in a nonstandard directory <include dir>
2092   CPP         C preprocessor
2093
2094 Use these variables to override the choices made by `configure' or to help
2095 it to find libraries and programs with nonstandard names/locations.
