It was a completely new build dir.

In the end, because I imagine the Wireshark build needs a more recent
version of Python, but the base platform still needs Python 2.7.5, I
went with virtualenv and it seems to have worked.

   sudo pip3.6 install virtualenv
   virtualenv ./wireshark-master
   cd wireshark-master/
   source ./bin/activate
   cmake3 /path/to/wireshark/source

seems to work.
