Integrate cross-platform build system

[Koncord]

This will be cool for any OS. Especially if it CMake.

https://github.com/lacc97/XL-Engine/tree/cmake by @lacc97 has most of a cmake system, though there was a CMakeLists.txt missing from Math

target_sources(xlengine
                PRIVATE
                    "${CMAKE_CURRENT_SOURCE_DIR}/crc32.cpp")

In Ubuntu 16.04 I had to install a couple of libraries (any other non-standard libraries were already installed)

sudo apt-get install libdevil-dev libwildmidi-dev

I have some other notes here on getting it to run:
https://gist.github.com/lucasw/d61424098f8dab66b205509742068c43#gistcomment-2126763

I can launch it now and get a black screen. It looks like the UI is trying to load png files that aren't in the repo but haven't debugged to see if that code is actually running and silently failing. (Is it supposed to run Dark Forces if I run it from the right place relative to the installed GOB and exe files? Are there instructions somewhere for what to do?)

You're further than I, I just got this backtrace from gdb:

Program received signal SIGSEGV, Segmentation fault.

I haven't had a chance to look into it, but have you gotten this?

Strace just gave this:
open("Logs/log.txt", O_WRONLY|O_CREAT|O_TRUNC, 0666) = -1 ENOENT (No such file or directory)

I also have a few things in my branch.

(use the code highlighting rather than blockquoting, your tilde's are getting misinterpreted)

I had to manually create the Logs directory also- making the code do this would be easy, and fail out properly with an error message if it is unable to create the directory.

The Could not open font I resolved by copying Inconsolata.otf to a fonts directory relative to where I was trying to run xlengine.

I didn't have the Jack issue.

There a lot of things that I believe are failing that don't cause an error message or exit that probably should, I could make a new issue for those (and pr them eventually).

I don't see anything different in your fork, did you not push it into github?

Pushed to testing branch on my fork.
