I think you're talking about dlopen() vs. direct linkage of .so?

Here's some code to ground things a bit.

ifdef CONFIG_SPICE
CFLAGS+=$(SPICE_CFLAGS)
LIBS+=$(SPICE_LIBS)
endif

And specifically, there's a notion of the VDI interface added to
core qemu, which can be extended by simply registering callbacks to that
interface:

vl.c::main()
...
#ifdef CONFIG_SPICE
        ...
        spice_init(&core_interface);.
#endif
