Thanks for this, I was trying to understand what was going on from all the
fragments.

I think this is the key bit I was missing, that you want to make plugins
out-of-source.

While I understand the concept, I'm not sure about the practicality or
usefulness of this.  Won't you still need all the (lib)wireshark headers to
compile the plugin, thus still requiring source?  If this is true, what
practical advantage is there in building a plugin out-of-source, when CMake
already supports out-of-source builds (for the full package)?

While I'm all for making life easier for devs, if no-one else has
identified this as a need, i.e. only you find it worthwhile, then we will
end up with stuff not generally used in the repo and then who will be
maintaining these bits of CMake?

I'm not intending to be negative, just want to understand where things are
at and maybe expose them a bit more to others on the list.
