Assuming it is not defined ... Then I don't understand is why `make` thinks the pixma backend should be built when HAVE_LIBJPEG is undefined. Its compilation should have been disabled by `configure` and shouldn't be listed in BACKEND_LIBS_ENABLED in backend/Makefile. > What's going on here?

Can you re-run `configure` and provide the `config.status` and `config.log` files?
