I thought about it and came to the conclusion that this might
produce misleading error messages on systems where SDL_image
is installed and SDL_mixer isn't.

However, the following variant should be okay:

    PKG_CHECK_EXISTS([SDL_image],
        PKG_CHECK_MODULES([SDL_image],
        AC_CHECK_LIB(SDL_image, ...)
    )

    PKG_CHECK_EXISTS([SDL_mixer],
        PKG_CHECK_MODULES([SDL_mixer],
        AC_CHECK_LIB(SDL_mixer, ...)
    )


@Andreas Roever: Maybe this variant is also interesting for
Topper and Pushover?
