Well that kind of sucks, cause the on Redhat 7.X the newest cmake is

Will the needed cmake be part of the toolchain ?

Subject: CMake migration complete
Hi all,

Zephyr has finally migrated to CMake.

This migration is an important step in a larger effort to make Zephyr
easy to use for application developers working on different platforms
with different development environment needs.

Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.

This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no
should be necessary.

For users that just want to continue their work with minimal
disruption the following should suffice:

Install CMake 3.8.2 exactly

Port any out-of-tree Makefiles to CMake.

Learn the absolute minimum about the new command line interface:

# To do a clean build;

$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..

# For incremental builds;

$ cd build
$ make
