You can set this via config, as by default ccache is paranoid about being correct. But you can tweak it with things like setting a build directory home (this is great for me, as I'm the only user but compile things in say `/home/josh/dev/foo` and `/home/josh/dev/bar` and have my build directory as my dev directory and it's shared. (see https://ccache.dev/manual/latest.html for all the wonderful knobs you can turn and tweak).

Fantastic tool, the compression with zstd is fantastic as well.

I played with distcc (as I have a "homelab" with a couple of higher end consumer desktops), but found it not worth my time as compiling locally was faster. I'm sure with much bigger code bases (like yours) this would be great. Reason I used it it that archlinux makes it super easy to use with makepkg (their build tool script that helps to build packages).
