Subject: cmake: disable SSE4.2 by default
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=bac0af364a2c742ea9bb63199ddeee0edacdb2ac;p=rocksdb.git

cmake: disable SSE4.2 by default

this commit is not cherry-picked from fb upstream, as it added "PORTABLE"
and "FORCE_SSE42" to do this.
