1. win32:CONFIG(release, debug|release): LIBS += -L$OUT_PWD/../QLoggingLib/release/ -lQLoggingLib
   
2. else:win32:CONFIG(debug, debug|release): LIBS += -L$OUT_PWD/../QLoggingLib/debug/ -lQLoggingLib
   
3. else:unix: LIBS += -L$OUT_PWD/../QLoggingLib/ -lQLoggingLib
   
4. 
   
5. INCLUDEPATH += $PWD/../QLoggingLib
   
6. DEPENDPATH += $PWD/../QLoggingLib
