Use google benchmark as third partie dependencie for bench?

[ThomasRetornaz]

Hi
I heavily use google benchmark (https://github.com/google/benchmark) on various projects.
Linked to isssue #107, it may a good thing to have a benchmark to measure the provided speedup on various scenario.
What do you think?
(i could make a prof of concept on my side related to issue #107)
