I am following docs and after running make -j24 I see that sccache doesn't really cache the build:
~$ sccache --show-stats

Non-cacheable reasons:
-x 408
Cache location Local disk: "/home/jimmy/.cache/sccache"
The compillation is using scache, yet the /home/jimmy/.cache/sccache is empty - nothing is stored there.
