Howdy Darren,
So we've patched libxkbcommon so that it can take an environment
variable for the path, which the qml plugin sets. So what you need is
to get that package into your build. If you want to build on Vivid the
easiest way to do that is to add the Snapcraft PPA to your local
sources and ask Snapcraft to build with that.
$ apt-add-repository ppa:snappy-dev/snapcraft-daily
$ SNAPCRAFT_LOCAL_SOURCES=1 snapcraft
This is not required for building on Wily or Xenial (or beyond).
