[Bf-committers] CMake version bump for blender2.8

[Dalai Felinto]

Hi,

Ubuntu 14.04 is "stuck" with CMake 2.8. It's a LTS so they won't
upgrade their CMake. And it's still quite inside our 5 year support
goal.
What exactly do we need from CMake 3.x? If we really need CMake 3.0,
can we at least update install_deps.sh to handle cmake as well?

Regards,
Dalai

> fedora (F26) - 3.8.2
> pclinuxos - 3.7.2
> centos (6) - 2.8.12 (3.6.1 in EPEL)
> arch - 3.8.2
> mageia (6) - 3.7.2
> slackware (14.2) - 3.5.2
> gentoo - 3.7.2
