When building QEMU configure with --disable-gtk --disable-cocoa
on macOS we get:

  ../system/main.c:30:10: fatal error: 'SDL.h' file not found
     30 | #include <SDL.h>
        |          ^~~~~~~
  1 error generated.

Fix by adding the SDL dependency to main.c it's CFLAGS contains
the SDL include directory.

Fixes: 64ed6f92ff ("meson: link emulators without Makefile.target")

Looking at commit 88c39c8693 ("Simplify softmmu/main.c") I wonder
if this header is still required.

I think so, SDL has its own main() wrapper.  Anyhow:
