Add collaboration server
The XRInterface
and CAVEInteraction
plugins both support collaborating with other remote users (well, CAVE will support it after this ParaView MR is merged). This MR adds support to build the collaboration server and include it with ParaView packaged binaries. So far, support only extends to Linux.
This MR depends on !1213 (merged) so that zeromq
itself can first be built on Linux.
This MR also depends on first getting the collaboration server into it's own repository, happening here.
