I'd rather convert devel/swig to a sysdep only. swig2 should be
available on most platforms nowadays, and there is no reason to
package it in robotpkg.

My real problem here is that if I add "include
../../devel/swig/depend.mk" in wip/py-mraa, it complains about not
finding v2.0, even if mraa needs v3.0 and that it is currently
installed on my system.

Why/where/when?

For me it says this on ubuntu 16.04 & 18.04:

Interesting, I have swig3.0 and not swig2.0, and, on xenial,

After installing swig2.0,

I will check in a clean install to investigate

What's in the sysdep.log ?

On a clean install:

root@5c452463261a:~/robotpkg/wip/py-mraa# cat work.5c452463261a/sysdep.log
Missing system package swig>=1.3:

missing: /opt/openrobots/bin/swig
searching in /usr/local
missing: /usr/local/bin/swig

Please install it before continuing.
- SYSTEM_PREFIX or PREFIX.swig can be set to the installation prefix
of this package in robotpkg.conf.
- If no swig>=1.3 package can be made available in your
system, you can use the robotpkg version, by setting in robotpkg.conf
PREFER.swig= robotpkg

I see. I can do something to handle this situation.

However, you should probably 'apt install swig' instead of an explicit
'swig3.0'.
