Исправлена ​​ошибка импорта библиотеки повышения в QT на ОС Ma c

Question

У меня проблема с буст-библиотекой в ​​QT,

 ld: warning: directory not found for option '-L-L/usr/local/Cellar/boost/1.72.0/lib/'

my .pro file

INCLUDEPATH + = "/usr/local/Cellar/boost/1.72.0/include/" LIBPATH + = "- L / usr / local / Cellar / boost / 1.72.0 / lib / "

и моя функция:

void GenvTracking::chargerModels(){
    boost::filesystem::path p("..");
    for (auto i = boost::filesystem::directory_iterator(p); i != boost::filesystem::directory_iterator(); i++)
        {
            if (!is_directory(i->path()))
            {
                models.push_back(i->path().filename().string());
            }
            else
                continue;
        }
}

Я хочу использовать boost для положенных значений в векторе
