In which format should be provided the libzim? A .dll? A .lib?

Depends on https://github.com/kiwix/kiwix-build/issues/466

Any progress on this? I'm interested in using python-libzim in this project.

I was apparently successful in building .dll of libzim, but trying to make python-libzim use it yields the following errors:

> python setup.py bdist_wheel
Found lizim library and headers in local directory. Will use them to compile python-libzim.
Hint : If you don't want to use them (and use “system” installed one), remove them.

(I probably have to upgrade my MSVC installation; will try that and post any positive updates).

How does Kiwix make libzim work on Windows (I understand it's cross-compiled)? Can the binaries produced by the build process be made available?

We should and will move forward soon on this.
