Build as static/dynamic library to allow embedding in another applications.

[PerryWerneck]

A quick patch putting the application in 'main.c' and all other code as a library

Hey Perry, thanks for being interested in the project! I wasn't expecting any contributions this soon since I haven't added the proper documentation to the repo. I'm not quite sure I understand what your goal with this issue is. My vision for turtile is a simple standalone compositor like sway,dwl,hyprland etc.

[PerryWerneck]

I'm testing it as an embedded compositor in a kiosk application, that's why I did a few changes in the code to allow packaging the compositor, the sdk and libraries. It's being packaged only as rpm in https://build.opensuse.org/package/show/home:PerryWerneck/turtile if you want to take a look. Can be package in many other formats using the same tools.

[migueldeoleiros]

Oh cool! Would it cause issues if I deprecate the makefile in favor of the new meson system you submitted in #31 ?

I can't promise that I won't be making braking changes, since the project is very much in the making. There still is no window management, but I'll be working on that soon, and I may add some options for both tiling, floating and kiosk-like fullscreen windows

[PerryWerneck]

Yes, but will be minor and easy to fix issues, actually, using meson will be even better to me since I'm already using it in my kiosk app.
