[ 83%] Linking CXX executable game /usr/bin/ld: CMakeFiles/game.dir/Game/Renderer_SDL.cpp.o: undefined reference to symbol 'SDL_CreateTexture' /usr/bin/ld: /usr/lib/libSDL2-2.0.so.0: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status make[2]: [CMakeFiles/game.dir/build.make:489: game] Error 1 make[1]: [CMakeFiles/Makefile2:110: CMakeFiles/game.dir/all] Error 2 make: *** [Makefile:84: all] Error 2

This isn't the first time I've had this problem with other code bases, but, I've never seen a method to correct for this.

Hi, make sure your system has SDL installed on it.

I solved it by updating this line: https://github.com/eezstreet/OpenD2/blob/master/CMakeLists.txt#L68 to

    target_link_libraries(game ${SDL2_LIBRARIES} SDL2 SDL2_net SDL2_mixer m dl)

Ran into the same issue, fixed doing the same.
