error compiling for QtCppIntegration

[mzeal]

I am trying to build qwt-5.2 for Qt build with QtCppIntegration namespace
./configure -release -qtnamespace QtCppIntegration -qtlibinfix CppIntegration
and I have compilation errors telling me that qwt also has to be built for QtCppIntegration:
Can someone someone tell me how? I checked qmake manual, but could find a clue to how set the namespace there.

I have exactly the same problem.
Any clues?
