You need to update your project. Go to the project properties by right-clicking on it in Solution Explorer and then select Properties. Then:

• In C/C++->General->Additional Include Directories you must set the Qt installation include path;
• In Linker->General->Additional Library Directories you must add the path of .libs files of your qt installation;
• In Linker->Input->Additional Dependencies you must put the name of .lib files that you need in order to build the project.

If it's a Qt project, you should also have the Qt plugin installed, in order to work properly with moc and other Qt features.

In alternative (that I suggest) you can create a CMake project and open in in Visual Studio.
