PlotJuggler with Fast-CDR-2.x.x (#920)

* Update minimum cmake version

Updated minimum cmake version otherwise fastcdr find package fails.
As the issue is about building with fastcdr installed from eProsima
reposotories I need it to work.

[#919]

* Update Fast-CDR thirdparty

If this commit is applied then plotjuggler will be able to compile and
run with Fast-CDR version 2.x.x from eProsima.
It can compile from:
- local thirdparty folder included within the repo
- install of fastcdr within the machine (usually /usr/local)

to do so:
- Udpated files, API and namespace names

Done it because I need to use plotJuggler with latest lib from eProsima
and I would like this to be available for everyone.

Issue:
[#919]

* Fix CI, added missing files

Added missing files from Fastcdr Ci shall build.
PlotJuggler build again with or without fastcdr package installed.

Issue:
[#919]

* Update CMakeLists.txt
