How to connect PSQL driver to Qt Creator project?

Question

PostgreSQL

Available:
1.Windows 7 64bit;
2. PostgreSQL 9.5 32bit;
3.Qt Creator 4.5;
4.Qt lib 5.10.0;
5.MinGW 5.3.0 32bit
Task: connect the PSQL driver to the Qt project.
I have already tried all the methods that are displayed on the request "qt build postgresql driver". The driver is still not going.
Most sources advise collecting in this way:

qmake"INCLUDEPATH+=C:\PostgreSQL\9.5\include""LIBS+="C:\PostgreSQL\9.5\lib\libpq.lib" psql.pro
mingw32-make

I get this error:

Console output when starting the project:

Available drivers: ("QSQLITE", "QMYSQL", "QMYSQL3", "QODBC", "QODBC3", "QPSQL", "QPSQL7")
QSqlDatabase: QPSQL driver not loaded

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    QSqlDatabase db = QSqlDatabase::addDatabase("QPSQL7");
    db.setHostName("188.120.232.***");
    db.setDatabaseName("postgres");
    db.setUserName("postgres");
    db.setPassword("123");
    if (!db.open()) {
        cout«"Crash "«endl;
    }
    else
        cout«"Ok"«endl;
    return a.exec();
}

Who faced such problem? How did you manage to win?

I managed to solve it by throwing the libpq.dll file into the
{Path to Qt}Tools\mingw530_32\i686-w64-mingw32\lib
folder.
Only the dll that was in the folder of the installed PostreSql did not fit, I had to compile all the libraries from this article and take it from there libpq.dll
