From: Sven Eckelmann Date: Sun, 23 Feb 2020 09:26:22 +0100 Subject: cmake: Switch to external SDL2 configuration file The Debian bullseye libsdl2-dev package moved its header files to a non-common path. Instead the sdl2-config.cmake is shipped with the package. This file is automatically used when the it finds no FindSDL2.cmake in our cmake modules directory.
