Just here to provide moral support. Go CMake go! :)

After discussing with several other Ceph developers and Sage, I wanted
to start a discussion about making CMake the primary build system for Ceph.
CMake works just fine as it is (make -j4 on master with CMake builds
350% faster than autotools!), but there's more work needed to make it
into a first-class build system.
Short term (1-2 weeks):
- Making sure CMake works on all supported platforms: Centos7, RHEL7,
Ubuntu 14.04 & 12.04, Fedora 22, Debian Jessie, Debian Wheezy are the
target platforms I have noted to test on already.
- Adding a target similar to make check
- Creating CMake targets that build packages (such as for rpm or debian)
- Writing documentation for those who haven't used CMake before to smooth the
transition over
- Making sure no targets or dependencies are missing from the
current CMake build, and that CMake supports all current
targets, configurations and options
- Replacing the integration autotools has with any automated build/test
systems such as the gitbuilder
Longer term (2-4 weeks):
- Removing the current autotools files, to avoid doubling build system
workload
- Adding more but shorter CMakeLists.txt files to a tree like structure
where a CMakeLists.txt would be in every subdirectory
I'm already working on a target similar to the make check target, and plan
on working on the other short term goals over the next weeks and beyond.
I wanted to get feedback from the community any reasons why someone started
using
CMake but stopped (ex: lack of functionality), and more broadly, on what other
obstacles there might be for the transition.
