Measurements between buildsystems

People,

I was just trying to measure some stuff here at work, and:

qmake based Make build:

make -j6  127.35s user 5.83s system 343% cpu 38.721 total

cmake based Make build:

make -j6  78.33s user 5.03s system 315% cpu 26.440 total

cmake based Ninja build:

ninja  76.61s user 4.50s system 339% cpu 23.919 total

the CMake buildsystem is almost a minute faster than the QMake, and
with more files comming in, this will probably get bigger. I'm using
CMake for the linux build now as default. :)
