How to fix "LNK2019 unresolved external symbol" error?

Question

I need to use C++ and Qt VS Tools in a project in Visual Studio 2022.

If I try to work with QtSql, I should include some specific libraries like <QtSql/QSqlDatabase>, <QtSql/QSqlError>, <QtSql/QSqlQuery>, but after initializing the Local Windows Debugger, I got this sort of errors:

Severity          : Error

        emit authenticationSuccessful();
    }
    else {

I know that it's a linker problem, but I tried to go to Project Properties -> Linker -> Input -> Add dependencies, and added Qt5Sql.lib and Qt5Sqld.lib, but it doesn't work, here's what I get:

Code        : LNK1104
