baldurk 768e812e45 Commit binary dependencies necessary for compilation on windows 
* On windows it's strongly desired to be able to compile straight out of
  a clean checkout or source download. This means anyone can download
  the source and investigate something quickly, without having to worry
  about the hassle of figuring out how the project downloads 3rd party
  dependencies, fetching them, getting them registered in the right
  place.
* This can't be put in a submodule as git submodules don't get
  downloaded by default so people new to git will get confusing
  compilation messages, and someone downloading the source from github
  directly without cloning via git won't get submodules included.
* It does add some extra size to a fresh download/checkout which is
  unfortunate, but absolutely worth the cost. Shallow checkouts still
  aren't unfeasibly large, and it's only a one-off cost at clone time.
