I'm replying to the digest, so if I do anything wrong, don't hesitate
to let me know :)

I suppose that should happen in this qmake invocation here, when
creating the Makefile, right?
------------- BEGIN
cd dbus/ && ( test -e Makefile ||
/mnt/Data/devel/source/qt/build.exp/qtbase/bin/qmake
/mnt/Data/devel/source/qt/qt5/qtbase/src/dbus/dbus.pro -o Makefile )
&& gmake -f Makefile
------------- END

I'll take a look at the qmake source, to figure out where this
detection/removal is happening.

OK, I'll try this, to see if it builds successfully.

If the workaround works, then I'll change the build dir (easier than
changing the source dir).

AFAICT, the safest way of changing the source dir is by cloning the
repo and running init-repository again in the new location, right?

I won't be able to get back to this before Monday, but I'll reply here
with a follow-up.

Thanks for your help.
