--WjW Hello, again Willem.

I did the following to test your PR:

git clone https://github.com/wjwithagen/ceph.git
cd ceph
git checkout ed634682263a27dddd2c1525b9720a0718382757
./do_cmake.sh -DWITH_SYSTEM_BOOST=ON -DWITH_LTTNG=OFF     -DWITH_REENTRANT_STRSIGNAL=ON     -DWITH_THREAD_SAFE_RES_QUERY=ON     -DWITH_OPENLDAP=OFF     -DWITH_LEVELDB=OFF     -DWITH_BABELTRACE=OFF     -DWITH_DPDK=OFF     -DWITH_SPDK=OFF

Unfortunately, I get the following error now.  Did I fetch the PR incorrectly?

CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
   Could NOT find verbs (missing: VERBS_LIBRARIES VERBS_INCLUDE_DIR)

Hi Mark,

I guess that that perhaps is not a thing to do, as I usually do not put my PR's in the head of my github. (I'm not really into git).

Wh I usually do with other peoples PR's is:
	fetch https://github.com/ceph/ceph/pull/24813.diff
and then patch that on my sources.
I have a script that does that, pre `cmake`

Then in due time the PR gets in ceph:master, and I get ride of the pathc.

--WjW
