Subject Re: update build instructions

Hi

For me it's more about correctness and reproducibility than build
times, nonetheless, seems that the ninja build is significantly faster
than the Make build:

Make:

real    4m32.779s
user    43m33.236s
sys     0m52.940s

CMake + Ninja:

real    3m30.794s
user    36m2.564s
sys     0m56.368s

Compiled on an g3.4xlarge with ebs

Provisioned IOPS SSD

io (115000 iops)
