参考 文章：

https://www.cnblogs.com/senior-engineer/p/5596976.html

导入qml插件主要分两个步骤：

1.main.cpp 代码例子

#include <QGuiApplication>

#include <QQmlApplicationEngine>

#include "roleentrymodel.h"

#include<QtQml>

#include "colormaker.h"

#include "person.h"

#include <iostream>

using namespace std;

int main(int argc, char *argv[])

{

    QGuiApplication app(argc, argv);

    qmlRegisterType<ColorMaker>("an.qt.ColorMaker",1,0,"ColorMaker");

    QQmlApplicationEngine engine;

    engine.addImportPath("../derivaticeTrading/plugin");

    QStringList mylist = engine.importPathList();

    for (auto i = 0 ; i <  mylist.size();i++) {

        cout <<"list =>" <<  mylist.at(i).toLocal8Bit().constData() << endl;

    }

    //engine.addImportPath("./demo");

    engine.load(QUrl(QStringLiteral("qrc:/view/main.qml")));

    if (engine.rootObjects().isEmpty())

        return -1;

    return app.exec();

}
