Description

I am attempting to cross-compile VulkanSceneGraph (vsg v1.1.15) under Windows 11 using the HarmonyOS SDK provided by DevEco Studio 6.1.1. The objective is to run my downstream project vsgPotree(https://github.com/geocapp/vsgPotree.git) on HarmonyOS to support point cloud visualization.
