How to build a Debug version log4cxx?

[Zhou Tao]

Hello all

I need to build debug and nodebug log4cxx library. However I don't
 know how to build a debug log4cxx library.

I could see there is a --enable-debug option when building the APR
library. But there are no the same option when building the APR-UTIL and
LOG4CXX.

Does anyone know how to get a debug log4cxx library?

Thanks tons.
