Things like this can be spotted e.g. in configure.in: AC_ARG_WITH(zlib, [ --without-zlib compile without zlib compression],[if test "$withval" = no; t hen disable_zlib=yes; else disable_zlib=no; fi]) +AC_ARG_WITH(brotli, [ --without-brotli compile without brotli compression],[if test "$withval" = n o; then disable_brotli=yes; else disable_brotli=no; fi]) AC_ARG_WITH(bzip2, [ --without-bzip2 compile without bzip2 compression],[if test "$withval" = no; then disable_bzip2=yes; else disable_bzip2=no; fi]) AC_ARG_WITH(lzma, [ --without-lzma compile without lzma compression],[if test "$withval" = no; t hen disable_lzma=yes; else disable_lzma=no; fi]) +AC_ARG_WITH(lzip, [ --without-lzip compile without lzip compression],[if test "$withval" = no; t hen disable_lzip=yes; else disable_lzip=no; fi]) compression="" (this is from sources links-2.14 and links-2.16).
