I note that Mysql (yeah I know, we don't love 'em greatly, but their
product niche is similar to ours) and Ceph (ok it is a distributed
storage system but still a highly popular open src product) have
switched to using cmake (relatively) recently. Both these projects were
using autoconf etc related builds previously and seem to be doing just
fine with cmake.
