There was some discussion on the list a while back about how we don't
really need to go through the full autoconf + ./configure + "make rpm"
routine simply to generate packages with the right version information.
My conclusion was that we should be able to generate a release tarball
(and even SRPM or RPM) with a shell script, rather than trying to do it
in autotools with a make target.

The reasoning was speed and efficiency: there's no point to running
"./configure" to generate an SRPM when the RPM itself runs "./configure"
during its build.

I don't know how well this maps to CMake, and whether CMake gives you
some sort of "skip everything and immediately do <foo>"... clearly I
need to learn more about CMake :)

We hope to eventually replace gitbuilder with something more scalable
like Jenkins, but in the meantime we're maintaining both systems :(

gitbuilder is https://github.com/ceph/autobuild-ceph
Jenkins is https://github.com/ceph/ceph-build

And then Loic also runs a make check bot in his own Jenkins instance.
