Good catch!  Yes that causes the problem; seems that 4.5.2 changes the
order of searching for headers, that's why 4.4.0 does find the correct one.

The parameters are generated by Qt (i686-pc-mingw32-qmake) with the help
of pkg-config (no problem on the .pc files), I'm looking into qmake.conf
to see how the include got there.
