# ONE FIX: /usr/lib64 added to work on Fedora
#
#
# This module looks for clucene (http://clucene.sf.net) support
# It will define the following values
#
# CLucene_INCLUDE_DIR = where CLucene/StdHeader.h can be found
# CLucene_LIBRARY_DIR = where CLucene/clucene-config.h can be found
# CLucene_LIBRARY = the library to link against CLucene
# CLucene_VERSION = The CLucene version string
# CLucene_FOUND = set to 1 if clucene is found
