#### building
- Requires C++17 and CMake
- The [SDL2 platform backend](https://github.com/NoelFB/blah/blob/master/private/blah/internal/platform_backend_sdl2.cpp) can be enabled in CMake with `BLAH_USE_SDL2`, and setting `SDL2_INCLUDE_DIRS` and `SDL2_LIBRARIES`
- The [OpenGL graphics backend](https://github.com/NoelFB/blah/blob/master/private/blah/internal/graphics_backend_gl.cpp) can be enabled in CMake with `BLAH_USE_OPENGL`.
- The [SDL2 platform backend](https://github.com/NoelFB/blah/blob/master/private/blah/internal/platform_backend_sdl2.cpp) can be enabled in CMake with `SDL2_ENABLED`, and setting `SDL2_INCLUDE_DIRS` and `SDL2_LIBRARIES`
- The [OpenGL graphics backend](https://github.com/NoelFB/blah/blob/master/private/blah/internal/graphics_backend_gl.cpp) can be enabled in CMake with `OPENGL_ENABLED`.
- Other backends can be added by implementing the [Platform Backend](https://github.com/NoelFB/blah/blob/master/private/blah/internal/platform_backend.h) or [Graphics Backend](https://github.com/NoelFB/blah/blob/master/private/blah/internal/graphics_backend.h).
