objectbox-c Support Windows ARM64 architecture

First of all, thank you for the great work on ObjectBox. I was wondering if you could add support for Windows ARM64. With more devices moving to ARM, it would be great to have ObjectBox working smoothly on that architecture. This would also make development and deployment much smoother for teams targeting cross-platform environments

Feature Request:

Add support for Windows ARM64 builds of ObjectBox.

Thanks again for your consideration, and please let me know if there’s any way I could help with testing or providing feedback on early builds.

According to this, we have a first windows arm64 running: https://github.com/objectbox/objectbox-c/actions/runs/18221604203/job/51907759660

Check the 5.0.0-rc release for the objectbox-windows-arm64.zip - maybe you can already check the dll. It will likely be integrated better in the final 5.0.

Update: DLL is available via GIT_TAG v5.0.0-rc2 in CMake. But the generator still needs to be built for arm64.

Thanks @greenrobot for the update. Regardless, the x64 generator should be able to run in windows on Arm, correct?
