Hi, anyone ending up here who wants to build either this or Meridian's OXCE on Linux;
judging from his OXCE compile guide, (and my failure to compile otherwise), you want to have the development versions of each library installed, the cmake method in particular (now the main supported OXCE build method) only plays nice with the -devel versions.
If you're on Fedora, like I am, you're in luck, because all the dependencies are the core repo/RPM (I didn't check to reference). The package names are: [dnf install] SDL-devel SDL_mixer-devel SDL_image-devel SDL_gfx-devel yaml-cpp-devel
Super simple and consistent, and according to Meridian on Ubuntu it's [apt install] libsdl1.2-dev libsdl-image1.2-dev libsdl-mixer1.2-dev libsdl-gfx1.2-dev
though you need to compile yaml-cpp for yourself since it's not in the Repos. Meridian has OXCE Binaries for Ubuntu and Debian, if you're on either of those go there before compiling.
