How to use CuteLogger in a Qt qmake based project, on macOS?

Question

I was able to build the CuteLogger library on macOS with

git clone [email protected]:dept2/CuteLogger.git

• debug

mkdir x64d
cd x64d
cmake .. -DCMAKE_TOOLCHAIN_FILE=~/vcpk/scripts/buildsystems/vcpkg.cmake -DCMAKE_BUILD_TYPE=Debug
cmake --build . --config Debug

• release

mkdir x64
cd x64
cmake .. -DCMAKE_TOOLCHAIN_FILE=~/vcpk/scripts/buildsystems/vcpkg.cmake -DCMAKE_BUILD_TYPE=Release
cmake --build . --config Release

That led to

x64d/libCuteLogger.dylib ~40M
x64/libCuteLogger.dylib ~33M

which I included in another project, the one which comes in the cutelogger README

#include <QCoreApplication>
#include <Logger.h>
#include <ConsoleAppender.h>

int main(int argc, char* argv[])
{
  QCoreApplication app(argc, argv);
  
  ConsoleAppender* consoleAppender = new ConsoleAppender;
  consoleAppender->setFormat("[%{type:-7}] <%{Function}> %{message}\n");
  cuteLogger->registerAppender(consoleAppender);
  
  LOG_INFO("Starting the application");
  int result = app.exec();
  
  if (result)
    LOG_WARNING() << "Something went wrong." << "Result code is" << result;
  return result;
}

And I build this with qmake

QT -= gui

CONFIG(debug, debug|release) {
     d = d
} else {

}

INCLUDEPATH += ../include
       LIBS += -L$$PWD/../x64$$d -lCuteLogger

SOURCES += \
        main.cpp

mySetOfExtraFiles.files += $$PWD/../x64$$d/libCuteLogger.dylib
mySetOfExtraFiles.path = Contents/Frameworks
QMAKE_BUNDLE_DATA += mySetOfExtraFiles

But running it gives

objc[23564]: Class QMacAutoReleasePoolTracker is implemented in both /Users/user/QtProjects/Cutelogger/x64d/libCuteLogger.dylib (0x1122ae5a0) 
and /Users/user/QtProjects/CuteLoggerProject/_x64d/CuteLoggeProject.app/Contents/MacOS/CuteLoggeProject (0x10f0ec0f0). One of the two will be used. Which one is undefined.

objc[23564]: Class QT_ROOT_LEVEL_POOL__THESE_OBJECTS_WILL_BE_RELEASED_WHEN_QAPP_GOES_OUT_OF_SCOPE is implemented in both /Users/user/QtProjects/Cutelogger/x64d/libCuteLogger.dylib (0x1122ae618) 
and /Users/user/QtProjects/CuteLoggerProject/_x64d/CuteLoggeProject.app/Contents/MacOS/CuteLoggeProject (0x10f0ec168). One of the two will be used. Which one is undefined.

objc[23564]: Class KeyValueObserver is implemented in both /Users/user/QtProjects/Cutelogger/x64d/libCuteLogger.dylib (0x1122ae640) 
and /Users/user/QtProjects/CuteLoggerProject/_x64d/CuteLoggeProject.app/Contents/MacOS/CuteLoggeProject (0x10f0ec190). One of the two will be used. Which one is undefined.

objc[23564]: Class RunLoopModeTracker is implemented in both /Users/user/QtProjects/Cutelogger/x64d/libCuteLogger.dylib (0x1122ae690) 
and /Users/user/QtProjects/CuteLoggerProject/_x64d/CuteLoggeProject.app/Contents/MacOS/CuteLoggeProject (0x10f0ec1e0). One of the two will be used. Which one is undefined.

So, what is that Class ... is implemented in both ...?
