But those dependencies are dependent on a PACKAGECONFIG setting, so
you'll potentially be forcing a build of libjpeg purely to satisfy a
fetch from sstate of a JPEG-disabled gdk-pixbuf.  Also, libtiff and
libjasper are missing.

If we can't change the sysroot creation order so that the order is
zlib, libpng, libjpeg, and then gdk-pixbuf then I think this needs to
be pulled out to a function that can do neater logic, such as iterate
through PACKAGECONFIG and add the required dependencies (for each
enabled option, turn the build depends into
%s-native:do_populate_sysroot_setscene).
