"yes"/"no" is only used on the user end. Both Meson and the Makefile always use
`=1` for the `-D` arguments. However, what is rather unfortunate, they only ever
provide `1` and never `0`. So the only way to use it is useful is indeed with #if.

I think this should change... but that's not a reason to postpone your patch.
If you want, you can go on with #if.
