VisionOS build support

[demonixis]

Hello,
Is it possible to you to add compiled binaries for Apple Vision Pro? It's a new target on 5.4.
Best,

[kring]

We don't have a Vision Pro, but we welcome a pull request that adds support if you're up for it!

[demonixis]

It works like the iOS port, all we need are compiled libs for VisionOS. If you use cmake, it's pretty simple to do that.
I can do the change on the build.cs files to add VisionOS support, it'll have the same library name, so basically

This is the only change to do if (Target.Platform == UnrealTargetPlatform.IOS || Target.Platform == UnrealTargetPlatform.VisionOS)

[kring]

Sounds good @demonixis. Please open a PR with that change, we'll throw it at our CI system, and then you can test out the build it produces. If it works, we can start including those binaries in the official release.

Got it, I just forked the repo. What is the best branch to start with? Is main ok?

[kring]

Yep, main is perfect.

Is there a Cesium for Unreal Plugin that supports VisionOS

[demonixis]

@plmokn107 not yet, I've forked the repo to make a PR with VisionOS support but don't had the time recently to submit it.

[demonixis]

Hey @kring just submitted an initial PR with VisionOS support.

I tried to compile the cesium libs for the VisionOS platform, but encountered some errors. Can you help me find the cause of the errors.

The problem was solved by adding the visorOS platform in build.cs, and now the Earth can be viewed in visionPro
