I'm having the famous linking error when trying to combine Qt and VTK. I've done all the steps of installing Qt with VTK correctly so I don't know what could possibly be wrong.
I'm using windows 8 with Qt5 and VTK 6.3 on visual studio.
Here is the error I get:
Drawing.obj : error LNK2019: symbole externe non résolu "__declspec(dllimport) public: __thiscall QVTKWidget::QVTKWidget(class QWidget *,class QFlags<enum Qt::WindowType>)" (__imp_??0QVTKWidget@@QAE@PAVQWidget@@V?$QFlags@W4WindowType@Qt@@@@@Z) référencé dans la fonction "public: __thiscall Drawing::Drawing(void)" (??0Drawing@@QAE@XZ)
1>Drawing.obj : error LNK2019: symbole externe non résolu "__declspec(dllimport) public: virtual __thiscall QVTKWidget::~QVTKWidget(void)" (__imp_??1QVTKWidget@@UAE@XZ) référencé dans la fonction "public: __thiscall Drawing::~Drawing(void)" (??1Drawing@@QAE@XZ)
And here is the code I use:
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QVtk w;
w.show();
//start();
return a.exec();
}
I followed everything that was written here: Combining Qt 5.4.1 with vtk 6.2.0 (using CMake GUI 3.2.1) on windows but somehow I get this error.
Also, I've added: $(QTDIR)\lib
to my additional libraries $(QTDIR)\include
to my "other include directories" and the followings to my additional dependencies.

EDIT:
I did not use CMake for the project as I have issues when using Cmake even with the small example provided on the wiki which gives the following error with the following CMakeLists.txt. NB: I use Visual Studio as a generator.
