OK, I'm now having similar problems with KParts (On a KUbuntu 14.10 this 
time), I've added "QT += KParts", and I get a compilation error: 
<KParts/MainWindow> not found.

$ cat /usr/lib/x86_64-linux-gnu/qt5/mkspecs/modules/qt_KParts.pri 
QT.KParts.VERSION = 5.3.0
QT.KParts.MAJOR_VERSION = 5
QT.KParts.MINOR_VERSION = 3
QT.KParts.PATCH_VERSION = 0
QT.KParts.name = KF5Parts
QT.KParts.defines = 
QT.KParts.includes = /usr/include/KF5/KParts
QT.KParts.private_includes =
QT.KParts.libs = /usr/lib/x86_64-linux-gnu
QT.KParts.depends = KIOWidgets KXmlGui KTextWidgets
$ ls /usr/include/KF5/KParts/KParts/MainWindow 
/usr/include/KF5/KParts/KParts/MainWindow

So everything seems OK, but the gcc command line doesn't contain the -isystem 
/usr/include/KF5/KParts, strangely enough all include path of KParts 
dependencies are added to the command line...

Again my workaround was:
INCLUDEPATH += /usr/include/KF5/KParts
LIBS += -lKF5Parts
