[CMake] Speed up warm builds by removing CCACHE_CONFIGPATH, which points at a
file that was never added
https://bugs.webkit.org/show_bug.cgi?id=322654
rdar://185926481
Reviewed by David Kilzer.
The cocoa preset sets CCACHE_CONFIGPATH to Tools/ccache/ccache-webkit.conf, a
file that has never existed. It was added in 311103@main alongside a config
that did not land with it.
CCACHE_CONFIGPATH replaces the per-user configuration rather than layering on
top of it, so a missing file falls back to ccache's built-in defaults instead
of ~/Library/Preferences/ccache/ccache.conf. That drops max_size to 5 GiB. A
WebKit build does not fit in 5 GiB, so the cache evicts about as fast as it
fills -- on one affected machine, 15355 cleanups and a 10.88% hit rate over
219047 lookups.
Drop the setting so each developer's own ccache configuration applies.
CCACHE_BASEDIR is left in place; it is valid and keeps hits portable across
checkouts.
