Building on Windows

It's not clear to me how exactly to build on Windows. I have Mingw64 toolchain setup. This is what I tried:

$ git clone --depth 1 https://gitlab.com/gnuwget/wget2/
$ cd wget2

$ bash -x contrib/mingw

+ set -e
+ unset CC
+ unset CXX
+ PREFIX=x86_64-w64-mingw32
+ export 'PATH=/usr/x86_64-w64-mingw32/bin:/mingw64/bin:/usr/local/bin:/usr/bin:/bin:/c/Windows/System32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0/:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:/c/ProgramData/chocolatey/bin:/c/Program Files (x86)/GitHub CLI:/c/Users/duffe/scoop/shims:/c/Program Files/Microsoft VS Code Insiders/bin:/c/Program Files/Go/bin:/c/Program Files/nodejs/:/d/Software/bin'

I guess, I need to install some libraries. But again, not sure exactly which ones.

I also tried to look at the Gitlab CI Job but it seems to have a cache, that it builds against, and doesn't install the dependencies: https://gitlab.com/gnuwget/wget2/-/jobs/1778332085

For someone who has built this on Windows, could they provide me with a list of packages that I need?

Btw, why don't we provide prebuilt binaries? Since we're building in CI already, we could just upload the built artifacts, right?
