Speaking of which (and speaking of re-inventing the wheel)… I seem to have a 
lot of qbs-related files on my system despite the fact that I don’t actively 
use it.  (OK I tried to build some project on github once, one that is already 
trying to use it.)  E.g. under ~/.config/QtProject/qbs/1.10.0 it looks like 
some meta-info, the kind of stuff that cmake and pkg-config already has:

$ cat 
~/.config/QtProject/qbs/1.10.0/profiles/qt-4-8-7/modules/Qt/phonon/phonon.qbs
import qbs 1.0
import '../QtModule.qbs' as QtModule

QtModule {
    qtModuleName: "phonon"
    Depends { name: "Qt"; submodules: ['core'] }
    cpp.defines: ["QT_PHONON_LIB"]
    cpp.includePaths: ["/usr/include/qt4", "/usr/include/qt4/Phonon"]
}

I don’t know how it got there, but I prefer to have some understanding of what 
goes in my .config dir so that I can use a git repo to replicate the important 
stuff between systems (and ignore the rest, maybe even trash it sometimes).  Is 
there any way that mess can be avoided?  I mean really, meta-info about 
*system* packages going into my home dir, as if qbs could even rely on finding 
those files there, rather than being installed alongside the system package 
itself?!?

Maybe it’s better to continue depending on pkg-config, since it’s an old 
standard that we probably shouldn’t drop support for anyway, rather than 
duplicating it?
