Subject: build: Add `WITH_SYSTEM_FMT` option
X-Git-Tag: v19.0.0~212^2~1
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=421bf61fee35cb8158b4e7ee8a8e40a4089554d9;p=ceph-ci.git

build: Add `WITH_SYSTEM_FMT` option

The `WITH_SYSTEM_FMT` option builds against system fmt and will fail
if a suitable version is not found. It is defaulted to `OFF`.
