organize repository build system

[RodrigoDornelles]

I was thinking about bringing improvements to the project's build, if they make sense I can work on it to make it more accessible to compile.

• statical linking with nclua project.
  it's difficult for you to be using nclua for more than one project, it increases the installation friction in Ginga and also makes it less portable, if it were all a single binary I think it would be interesting, I think about how cmake already exists to fetch the repository, but already build together as a static library of Ginga itself.

• gssdp1.2 is old, maybe unecessary
  it could be an optional feature, or maybe downloaded by cmake or exchanged for another project, I also don't see the need for it to exist, as there are other projects, even from telemedia, that do this.

• Lua could be versioned locally
  it would be interesting to be able to choose the lua version, since televisions still use 5.1, and there is no need to install liblua5.1dev and a small vm, it could be statically linked by the project.

• gstreamming runtime linking
  While the application does not handle video, I think it would not be necessary to force the user to have gstreamer, if he tries to play a media then the linking can happen using dlopen.

• Indeed, the lua code could be integrated inside CMake,
• The gstreamer already does not play a mention that does not exist a library for it.
• The gssdp1.2 is used by the GingaCC-WS for support remote device access. There is a prototype of the RemotePlayer API implemented. I agree it could a param to enable build it from CMake.

I didn't know about the gstreammer part, so I'll adjust the build to only get headers locally from gstreammer, and be able to build without having it installed on the system machine.

I think that maybe it is not necessary to support sspd in ginga telemedia if it does not bring a complete ginga ccws, there is a telemedia project that mocks sspd that can run in parallel to telemedia. I am also building a ccws simulator to use in conjunction.

my 2 cents - I like the idea of the option to statically link to nclua.
