On macOS, I get the DllNotFoundException: UsdCs assembly:<unknown assembly> type:<unknown type> member:(null) error when trying to import USD files using my custom build of the USD package. This is on macOS only. What’s suspicious is what I see in my local package:

Notice the symlinks to missing USD artifacts in my local build. I tried rebuilding using different versions of CMake as old as 3.13 and all create symlinks. Looking at the CMake files, I see this list and this logic to install these files. However, it looks like on macOS this only install the symlinks and not the actual dylibs. Am I missing something ?
