      Description

      OS: Linuxmint 20 ulyana amd64

      Qt5.15.1 compiled from source with the configuration command

      ./configure -prefix /opt/Qt5.15.1 -gstreamer 

       When compiling a simple project using Qt and Bsoncxx 3.4.3 (from the C++ Mongocxx 3.4.3 driver for working with MongoDB) an error is displayed:

      Here is a small project to reproduce the bug

        return a.exec();
      }

      #ifndef TEST_H
      #define TEST_H
      
      #include <QObject>
      #include <bsoncxx/types.hpp>
      
      class Test : public QObject {
        Q_OBJECT

      signals:
      };
      
      #endif // TEST_H
      

      test.cpp 

      #include "test.h"
      Test::Test(QObject *parent) : QObject(parent) {}
      

      In Qt5.12.9, this code compiles correctly and without errors!

      Update 0:

      If you wrap all the include directives to include the bsoncxx/mongocxx header files in blocks

      #ifndef Q_MOC_RUN
      // start to include the bsoncxx/mongocxx library header files
      #include <bsoncxx/types.hpp>
      #include <bsoncxx/array/value.hpp>
      #include <bsoncxx/array/view.hpp>
      #include <bsoncxx/builder/stream/document.hpp>
      #include <bsoncxx/document/value.hpp>
      #include <bsoncxx/document/view.hpp>
      // etc
      #endif
      

      then the compilation is successful.
