-## Installation
-
-### Cannot specify compile definitions for target "SDL2::SDL2" which is not built by this project
-
-This error is specific to a few operating systems. The main cause is that your SDL2 version is too old and does not
-include the necessary CMake files defining the target. There is an indepth discussion about this
-[here](https://discourse.libsdl.org/t/how-is-sdl2-supposed-to-be-used-with-cmake/31275/16).
-As a solution, you should update your SDL packages to SDL >=2.0.12 or **compile the latest SDL2 and SDL2-image from
-source**. The latest version includes the necessary CMake files to expose the `SDL2::SDL2` target.
-
-## Building on Debian 12
-On Debian you might get an error saying that it couldn't find SDL2 library. This happens because the CMAKE prefix and SDL2 path are not set correctly.
-The solution is to append at the end of the `./configure` command the cmake variables for both the prefix and SDL2 path, like so:
-`./configure <your configure opts> -- -DCMAKE_PREFIX_PATH=/usr -DSDL2_DIR=/usr/include/SDL2` (you can use `find` to look for the correct paths)
