Throwing compile errors in Lazy.h and AtumTensorDeviceType.h

[Kaleidio]

Describe the bug Unreal's build system throws a lot of API error logs when trying to compile with LibTorch 2.4.1+.

Environment Information

• OS: Windows 10 23H2
• Unreal Engine Version: 5.4.4
• Plugin Version: 0.1.2
• Built from:
  • Source:
  • 71bef6eee8fca3f3174f7d5fd0d9a759994f0ad2
  • LibTorch v2.4.1

Additional context 2.4.1 is quite young, so I assume these are breaking changes.

Is there more info on the version of LibTorch this plugin was built against? In the meantime, here are some hints as to what is going on.

I have now tried the versions of LibTorch below which all throw the same issue

• 2.5.0
• 2.4.1

seems to all stem from a template called cl0:OptimisticLazy<T> that fails to compile resulting in syntax errors.
