 Should we move Assimp to a Gem instead of using O3DE 3rdParty system?
 ---------------------------------------------------------------------
 
-Moving forward with USD via Assimp will require regularly pulling new versions of Assimp as new features come online (example: references). Going through the 3rdParty library system is slower as it requires its own approval process via [O3DE's 3rd Party Package repo](https://github.com/o3de/3p-package-source). The downside to moving Assimp into a gem directly, is that we'd reimplement what's already in 3rdParty, for example, [git pulling a particular Assimp commit](https://github.com/o3de/3p-package-source/blob/main/package-system/assimp/build_config.json#L2-L3), [building](https://github.com/o3de/3p-package-source/blob/main/package-system/assimp/build_assimp_windows.cmd), and [packaging](https://github.com/o3de/3p-package-source/blob/main/package-system/assimp/install_assimp_windows.json) the library.

This would also increase build time when compiling the editor source; Assimp takes 2 minutes to download and compile on my local 16-Core 3.4GHz PC.
 
 Should we fail a job, or emit an error if a reference to another USD file can't be resolved?
