h1. CMake

h3. Summary

I'm not sure if this is worth a separate blueprint, but, maybe as part

of some sort of general tools or processes session, I would like to

discuss the possibility of switching our build system to CMake.  There

is a preliminary branch from The Linux Box on GitHub [1] and a thread

on ceph-devel on this topic [2].

The numbers presented in [2] are a bit misleading, since AFAICT not

everything was built, and, as mentioned in that thread, we could

probably get some of the speedup by not building two versions of

everything with the existing autotools system, but, at least to me,

speed is not the only issue.  libtool is a huge PITA as it breaks the

ability to export source trees to VMs which leads to bloated VM images,

not to mention the need to compile everything separately for each VM.

CMake is also better supported by IDEs, which would benefit people who

use them, IMHO has a better language and somewhat easier to work with.

What I'm looking to get out of this is to gather opinions, see if

people would be open to this, and perhaps discuss some of the details,

e.g. gitbuilders, the oldest platform that needs to be supported, etc.
