Shadow builds on windows are broken:

<srcbase> = D:/qt5/qtbase
<outbase> = D:/qt5/build

The include pathes to <outbase> are broken, they all miss "\qt5\build":


cl ...
-I"d:\include"
-I"d:\include\QtCore"
-I"\include\QtCore\5.0.0"
-I"\include\QtCore\5.0.0\QtCore"

-I"global"
-I"d:\qt5\qtbase\src\3rdparty\zlib"
