There's a few dependencies that you need to build splashkit on Ubuntu linux. Here's all the ones I was missing. Hope this helps. ```bash sudo apt-get install cmake libglew-dev glew-utils gengetopt libimlib2-dev libglm-dev libxext6 libglew1.13 libglm-dev libegl1-mesa-dev libxrender-dev libicu-dev libpng12-dev libpng libssl-dev libcurl4-openssl-dev curl libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev libsdl2-gfx-dev libsdl2-net-dev libflac-dev libvorbis-dev libvorbisfile3 libmikmod-dev libogg-dev ``` Hope I didn't miss any. 😅
