Hey Stefano,

unfortunately this is not a stupid question at all. It is a bit tricky to get 
right with a Qt4 build at the moment. It's lacking documentation.

So, in order to enable that feature, QT_PRIVATE_INCLUDE_DIR should point to 
"$MY_QT4_IN_SOURCE_BUILD_DIRECTORY/include/QtCore". Note that you don't have 
to specify that variable via CMake flags or anything, it's auto-detected in 
case everything is alright.

It's important that you have an *in-source build* of Qt4 (the directory must 
contain both a src/ and include/ directory after having compiled Qt) -- it's 
currently not possible to make this work with an out-of-source build.

Hope this clears up things a bit. In case you need to debug further, have a 
look at the root CMakeLists.txt file in GammaRay.git.

Feel free to ping us on #gammaray on Freenode (IRC).
