Describe the bug
The scene index depends on usdSkelImaging, it is basically used to check if a mesh was skinned and remove the skinned normals in the scene index filter extComputationPrimvarPruningSIP.
This dependency to usdSkelImaging is problematic on linux when we load the render delegate in several DCC, maya, houdini. It appears that usd doesn't preload the library and when attempting to dlopen usdSkelImaging, the search paths are not available, usdSkelImaging is not found and the render delegate not loaded
