Using mold for Chromium discussion.

Hello, Im working on a chromium fork called Thorium > https://github.com/Alex313031/Thorium and would like to test using mold instead of lld during linking of the .so files and executables. How would I do this? I know this was one of the inspirations of the creator when making mold. Do I need to install or build/install mold first, or is it included in a chromium checkout? Can I just modify the main BUILD.gn to use LDFLAGS+= [ "-fuse-ld=mold", ]?
