Rather than tying this to CentOS explicitly, would it be better at the
start of the script to test e.g "which ninja" and "which ninja-build" and
use that to work out the command to use. It's possible to have ninja
installed directly from tarball on CentOS as "ninja" (as I have in my test
VM), and the binary might be called ninja-build on other systems too e.g.
RHEL, perhaps.
