Whether it's *better*, I don't know, but there's

static void
get_reordercap_runtime_info(GString *str)
{
    /* zlib */
#if defined(HAVE_LIBZ) && !defined(_WIN32)
    g_string_append_printf(str, ", with libz %s", zlibVersion());
#else
    g_string_append_printf(str, "");
#endif
}

which is a bit of a greasy hack - appending an empty string to str, just so it's marked as used - but I suspect the extra CPU time spent doing that, on platforms unlucky enough not to have zlib, will be lost in the noise.

You can set also
 g_string_append_printf(str, "without libz");
