I have a problem. I need to compile qt5 code on qt4. When I'm compiling it I have such error(on qt5 I haven't it):

```
QWebView: No Such File Or Directory

```

Here is my .pro file:

```
QT       += core gui xml webkitwidgets

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = TPDetector
TEMPLATE = app

SOURCES += \
    main.cpp \
    mainwindow.cpp \
    VKAuth.cpp

HEADERS += \
    mainwindow.h \
    VKAuth.h

```

How I can build my project on qt4?
