Can't build plugin on arm64 mac

[PhysicsDan]

Hello,
Trying make visit will fail with the error ld: symbol(s) not found for architecture arm64 on new Apple macs.

I added the line set(CMAKE_OSX_ARCHITECTURES "x86_64") to the top of the file SDF/VisIt/CMakeLists.txt and now the plugin works. I think the file is generated from somewhere else so it is probably not the correct way to do the fix.
