General / Trying to get SFML to work as a git submodule

« on: July 24, 2022, 11:03:57 pm »

I'm wanting to build a small framework for some different 3d projects I want to do. I normally use glfw but I've heard good things about sfml and wanted to try it out. I'm not particularly good at CMake but I'm getting an odd error and not really sure why considering I don't even reference the library in another lib or exe yet.

The error I'm getting is LNK2001 'unresolved external symbol=' for exports.def and LNK1120 'unresolved externals' for sfml-window-d.lib.

My folder structure  is
src/
  KEngine/
      CMakeLists.txt
   Sandbox/
      CMakeLists.txt
   Submodules/
       sfml/
       CMakeLists.txt
   CMakeLists.txt
