When creating a new app using SFML or SDL plus the respective Spine Runtime, I'd set it all up in a single CMake project. That's what our examples do. The alternative is to compile each of those things into .dlls or static .lib libraries, which is a major pain, especially if you want to modify the source code. The "everything in a single CMake build" also enables you to more easily debug everything.
SFML jpeg.lib?
Mario That's what I did with sdl!! When I generated the examples with cmake, .lib files where made and I just made a folder inside my project solution and moved those files to the lib folder I made and then just like that, it worked liked magic! Not sure if I did that right, but hey, it's working and I'll take it!
