This is a subset of Qt for use with https://github.com/devinacker/bsnes-plus for development and distribution purposes only, to permit building of bsnes-plus without adding Qt to Windows' PATH.
This should be updated from the full Qt distribution, and should only include the same files (or a similar set) as what is initially present.
Being a partial, but otherwise unmodified, copy of Qt's offline distribution, this is still beholden to Qt's license.
