Add Linux support

[kkremitzki]

This is something I'm interested in working on but I figured I'd create an issue to track the work in case anyone else wants to jump in.

Currently building fails on Linux with this totally unsurprising error about a missing winsock2.h:

[  7%] Building CXX object CMakeFiles/ggpo.dir/src/lib/ggpo/main.cpp.o
In file included from /home/kkremitzki/Desktop/Source/ggpo/git/src/lib/ggpo/main.cpp:8:0:
/home/kkremitzki/Desktop/Source/ggpo/git/src/lib/ggpo/types.h:12:10: fatal error: winsock2.h: No such file or directory

          ^~~~~~~~~~~~
compilation terminated.
CMakeFiles/ggpo.dir/build.make:62: recipe for target 'CMakeFiles/ggpo.dir/src/lib/ggpo/main.cpp.o' failed

Once the build works on Linux I can proceed to getting it packaged for Debian/Ubuntu.

If you apply #16 and #17 locally I expect it will work. Let me know if there's any problem.

[kkremitzki]

Thanks, I opened #21 which will get things working after #17 is merged.

Please see #37. I just merged your code #21 to the dev/crossplatform branch plus the original changes in #17.

To port the vectorwar example application I thought we could replace the gdi_renderer and all the Window specific code with a simple libsdl implementation (using sdl_ttf for text rendering). The simple 2D rendering primitives available in libsdl should work on Windows, Linux and MacOSX.

Does that sound reasonable?

@arrayofchar does this mean Linux Support is added already and this issue is closed?

I'm not sure how much cross platform support there is. I think I got it to build in a Ubuntu VM. I've not tested the actual functionality. You should compare the cross platform branch with the main branch

I have ported the "vectorwar" example application to Linux based on the linux support branch here: https://github.com/pond3r/ggpo/pull/57

This probably has bitrotted quite a bit but back then on a local machine, the vectorwar example application worked on Linux as well as Windows with up to 4 players IIRC. I have not tried running the application over the network but in theory (!) it should just work.

Has any progress been made on the linux/unix support? I'm looking through the development/crossplatform branch and it seems to still heavily utilize Win32 API and types. Unless there were some macros I missed.
