Dear Olivier Schonken,

Please use the Buildroot mailing list for such discussion. I've added
it in Cc.

You should *not* distinguish between host patches and target patches.
This is really bad as the source tree should be the same for the host
and the target builds, and I've sent just two days ago a patch series
that was precisely fixing the packages that are currently doing this.

So, what you should is instead add an option like --disable-cups in the
configure.ac, which defaults to enabled, and in the Makefile.am, only
add the cups sub-directory to the SUBDIRS variable if CUPS is enabled.
Preferably, it should be done in a form that allows the patch to be
submitted upstream.

You can look at
http://lists.gnu.org/archive/html/bug-gettext/2013-05/msg00035.html for
an example I've submitted upstream to gettext.

Note that apparently, gutenprint already has a --without-cups option.
So maybe your work is really to figure out why this option doesn't
disable the CUPS build.

Thanks!

Thomas
