--prefix=DIR                Prefix where Lua should be installed.
                            Default is $PREFIX. Creates \$PREFIX/bin,

                            Used by Lua.
                            Default is $READLINE_DIR
--with-ncurses=DIR          Prefix where NCurses is installed.
                            Used by Lua when Readline is enabled.
                            Default is $NCURSES_DIR
--without-readline          Disable Readline support when building Lua.
--from=URL                  Install from LuaRocks repository URL
--with-$PACKAGE_OPT=VERSION
     Installs the provided $PACKAGE version instead
     of $PACKAGE $PACKAGE_VERSION
--without-$PACKAGE_OPT
     Does not install $PACKAGE, just Lua and LuaRocks
--without-rocks             Does not install LuaRocks and $PACKAGE, just Lua
--bootstrap                 Also downloads Lua, LuaRocks, and the rocks for
