This looks more complicated than just a missing dependency info if I read the 
logs correctly:
- KMime is retrieved as a dependency (ie. build metadata should be correct).
- There is no Windows CI build for KMime!? That makes it hard to check which 
version was actually built, or where KMime comes from at all here.
- Looking at past CI state, it alternates between working and the KMime being 
too old error every few builds. It breaks when the dependency version is 
bumped, but then gets back to working without any code change.

So I'm a bit lost here on what is happening, the lack of a KMime Windows build 
on the CI would seem suspicious though.
