How to resolve LNK2019 error obtained after initializing the web engine and writing code to load a web page?

[gouneken]

Good evening to the whole community, I am working on a search engine project for android phone. In order to orient myself, I tried the code present on the official documentation https://doc.qt.io/qt-6/qml-qtwebengine-webengineview.html#details to initialize a web engine and load a web page. But when I run I get the LNK2019 error followed inevitably by the LNK1120 error. Firstly, I looked at the documentation code for the main.cpp and main.qml files and everything was normal. Then I searched the internet for how to resolve this error, and I was asked to use vcpkg, but I don't really see the importance. I don't know if this is a documentation code error or something else. I therefore ask for your help for those who may have already dealt with this.
The error text is the follow:
LNK2019:external symbol not resolved "_declspec(dllimport) void_cdecl -----QtWebEngineQuick::initialize(void)"(imp?
initialize@QtWebEngineQuick@@YAXXZ)r,f,renc, in the main function
main.obj
I look forward to your answers. Thank you!
