My answer on reddit:

The -framework flag on Mac is a linker flag. Linker flags are 
handled in DUB via the lflags entry. Assuming XLinker is being 
used, it should probably look something like this:

```
"flags": ["-framework", "CoreVideo", "-framework", "IOKit"]
```

In other words, a string for the -framework flag and the 
framework name for each of the frameworks you need. Because 
according to the forum thread below, passing them to DMD directly 
requires the -L switch (meaning, the library flag switch) for 
both -framework and the name.

(Ignore the bit about the link pragma in that thread... that's 
specific to an old build tool that's no longer around).
