Recent GIR files

I’m trying to get Aravis working on Windows with Free Pascal/Lazarus. I mostly hacked the existing gobjects introspection to also support Windows. Many simple examples already work (though no streaming yet)

However I’m missing symbols in the aravis header, specially relating to GVCP, probably because I have an old GIR file for 0.8 from the Rust header GITHUB repo. Where can I find up to date GIR files?

I use the pregenerated DLLs, so if it is by product of building can sb upload recent ones somewhere?
