      1. Clone qtbase.
        I'm at f071ba31b2e441268518217cbe2ec4fe1c978b31
      2. Do shadow builds of this in empty directories.
        I used: 
        MAKEFLAGS=-j7 nice ../qtbase/configure -platform linux-clang -opensource -confirm-license -nomake examples -nomake tests -prefix $PWD -release <buildtool> && nice make -j7

        with <buildtool> being -cmake or -qmake, respektively.

      3. Check the sizes of these builds: 
        qtrob@rob-desktop:/tmp/sizetest$ du -sh *make
715M	cmake
622M	qmake
