    I'm using 2019.4.25f1, and I'm very excited about being able to create Linux IL2CPP UNET server app builds from my macOS machine! I can create Linux builds using IL2CPP without issues, and it launches on my Debian server. However, when a user tries to log into my game, the server fails to load sqlite3.dll I have included in my game:

    Code (CSharp):
    1. DllNotFoundException: Unable to load DLL 'sqlite3': The specified module could not be found.

    19. (Filename: currently not available on il2cpp Line: -1)
    The same server app built on Mono runs fine because Mono.Data.Sqlite is used instead. What are some things I can do to have my IL2CPP Linux server app load sqlite3.dll successfully? Thanks.
