QCefView是一个与Chromium Embedded Framework集成的Qt小部件。
您可以使用QCefView而无需编写任何与CEF代码相关的代码。
这个Qt小部件是分布在二进制模块和LGPL许可的。
现在您可以尝试使用QCefView来开发您的应用程序，像使用其他QWidgets一样使用它。 QCefView小部件提供了几种方法来在本地C ++代码和Web代码之间进行通信。
您不需要编写通信业务逻辑。
首先将cef_binary_3.2704.1414.g185cd6c_windows64（或其他版本）解压再dep目录下
使用Cmake-gui工具配置生成sln工程文件
使用对应的VS打开sln进行编译构建，QCefView.lib以及QCefView.dll最后生成在out对应的目录下
详情请参考官方文档以及之前的文章。
基于QCefView的浏览器应用程序例子代码：Qt Creator工程
在工程目录下新建文件夹QCefViewSDK，将QCefView-master/out/QCefView下的include文件夹和lib文件夹拷贝在CefViewSDK目录下。
MSVC2017 64bit构建工程，将QCefView-master/out/QCefView/bin中对应配置的文件全部拷贝到输出目录中，在其中新建web文件夹，拷贝QCefViewTestPage.html到其中。
