Unable to remove log4cxx logger, got a lot of Linker unresolved External

[Andrein95]

Yes I removed also lib for log4cxx, apr, apr-util and xml. (libs that log4cxx require).

I removed also logsystem.h and all includes and reference to: 

#include <log4cxx/log4cxx.h>
#include <log4cxx/logger.h>

and also logsystem.cpp

In projects, ex: Messenger i Removed all LOG_xxx macro call but can't figure out why the linker can't resolve externals...
