[SailfishDevel] Problem running "old" project on QT5

[Markus Svensson]

OK, so I finally had some time to continue working on this little project. 

I've gotten the old QT4 classes out of the way and replaced with the QT5 counterparts - but I can't get the QT5 includes to stick. The compiler output clearly shows that it's still using the QT4 headers:

g++ -c -pipe -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -m32 -march=core2 -mssse3 -mtune=atom -mfpmath=sse -fasynchronous-unwind-tables -fno-omit-frame-pointer -Wall -W -D_REENTRANT -DDEPLOYMENT_PATH="\""/usr/share/SilicaNote/"\"" -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4 -Isailfishapplication -I. -o main.o main.cpp
main.cpp:1:22: fatal error: QQuickView: No such file or directory

So, how do I update the project to use QT5? I tried editing the Makefile - but it seems to be automatically generated by QT Creator for every build?

Grepping for "qt4/QtGui" just gives me the Makefile:

macbook-pro:SilicaNote markus$ grep -r qt4/QtGui *
Makefile:INCPATH       = -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4 -Isailfishapplication -I.
Binary file sailfishapplication.o matches

but I assume it's defined somewhere else what QT version is to be used? 

I realize it would probably be easier to just create a new project in QT Creator and copy my source files to it - but I would like to understand how this works behind the scenes as well... :)

Thanks!

Regards,
Markus
