Interesting remark, the builds were done inside docker container.

Still, they might be good tho, this machine has 28 cores/56 threads.


Nonetheless, wall time clearly show that qbs build way more stuff than
cmake, and does this in less time.
I might collect the load average while building, which will show that Qbs
is more efficient.
As well, the build time Vs job count graph might give clue.
