# - Find Log4Cxx

# Find the log4cxx logging library

#

# respects the BUILD_STATIC_BINS variable => searches for static library and its

# dependencies

#

#  LOG4CXX_INCLUDE_DIR  - where to find logger.h etc.

#  LOG4CXX_LIBRARIES    - List of libraries when using log4cxx.

#  LOG4CXX_FOUND        - True if log4cxx was found.
