# In SDL 2.24.0, the CONFIG method doesn't add a target for libSDL2main. Seen on Debian
# Unstable, and seems to be https://github.com/libsdl-org/SDL/issues/6119 which is reported
# upstream on macOS. For consistency's sake, let's add a phony library we can link with,
# which is also the workaround that upstream suggests in the bug report.
