Hmm, right, building with python support seems to be failing :/

I'll see if I can fix it. Do you have any objection if I push a patch to fix & re-enable python support?

Alright, the fix is simple, we just need to pass another option to cmake: -DUSE_PYTHON27_COMPONENT:BOOL=TRUE

Is python2 support going to be maintained after the upstream EOL on January 1, 2020?
Otherwise you would only be adding the feature back for seven weeks.

Upstream's added python3 support to git master, so hopefully we'll see a release of that at some point. My bad (and good) on dropping python2.
