QT WebView/WebKit issue - qt

Question

I'm trying to add a WebView to my GUI. First, the app crashed unexpectedly everytime. I figured I probably needed to import WebKit 3.0 along with WebView 1.1. After adding the required import statement, I try to run but it says that module "QtWebKit" is not installed. I checked the include folder and its indeed not there.
So my question is if QtWebKit is what I need, how do I install it?
Update:
When this code exists in my .qml file, the app crashes without starting:
WebEngineView{
anchors.fill: parent
url: "http://www.google.com"
}
This is the import statement I'm using on QT 5.6:
import QtWebEngine 1.1
This is the segmentation fault error generated because of the presence of the code mentioned above:
Full demo code:
import QtQuick 2.6
import QtQuick.Controls 1.5 as QC
import QtQuick.Controls.Styles 1.4
import QtGraphicalEffects 1.0
import QtQuick.Dialogs 1.2
import QtMultimedia 5.6
import Qt.labs.controls 1.0
import QtWebEngine 1.2
ApplicationWindow {
height: 640
width: 480
visible: true
Loader{
anchors.fill: parent
sourceComponent: webComponent
}
Component{
id: webComponent
WebEngineView{
anchors.fill: parent
id: web
profile: WebEngineProfile {
storageName: "Default"
}
}
}
}

Answer 1

Your debugger's stack trace shows that your crash is occurring in Qt's OpenGL functions. Remember to call QtWebEngine::initialize() before you start using Qt WebEngine.
Note also:
Qt WebView is a lightweight module for running your mobile OS's native web engine. Its main QML type is called WebView.
Qt WebKit is a heavyweight module for running a fully self-contained web engine. Its main QML type is also called WebView, but this is completely unrelated to the other WebView. This module is now deprecated.
Qt WebEngine is a heavyweight module for running a fully self-contained web engine. Its main QML type is called WebEngineView. This module is meant to replace Qt WebKit.

Qt WebKit is a deprecated module. Maybe you can install it from Qt sources, but since you want to use WebView 1.1 (and that you're on Qt5.6), I think you'd better use Qt WebEngine (using deprecated modules is not recommended).
You can already see it in your folder (modules QtWebEngine and QtWebView).
