Writing such an article would require a bit more work in term of
collecting and analysing data. As well, one would need to make sure
that the comparison is fair, which i'm not certain it currently is at
this stage. As well, to be complete, i would need to measure qmake
perf and cmake+make as well. I would need to check qbs with the
combineMocOutput option, ...
As well a comparaison when using a hot ccache could be useful to
measure overhead of the build system, ...
The dependency graph export i would like to write has actually nothing
to do with this perf comparaison and won't be useful. The 2 graphs
(product/target based) have to be identical, this is about correctness
