Where can I get fmodex?

I want ot build the Second Life Viewer for Mac with M1 Apple Silicon chip from the source code.

The Linden Lab’s official wiki page says FMODex package archive is required.

http://wiki.secondlife.com/wiki/Build_the_Viewer_on_macOS

The file name is like “fmodex-4.44.31.201503051234-darwin-201503051234.tar.bz2”.

I have tried to build it by myself but it was so difficult.

So, if there is a pre-built version of the library, where can I get that ?

There is no pre-built version of FMOD Ex for Apple Silicon. FMOD Ex has been deprecated for many years now.
