Without looking at the docs or sources:

This means the call looks something like this:

FIND_PATH(CLUCENE_LIBRARY_DIR
      NAMES CLucene/clucene-config.h PATHS $ENV{CLUCENE_HOME}/lib${LIB_SUFFIX}
    ${CMAKE_INSTALL_PREFIX}/lib${LIB_SUFFIX}
    /usr/local/lib${LIB_SUFFIX}
    /usr/lib${LIB_SUFFIX}
    /sw/lib${LIB_SUFFIX}
    NO_DEFAULT_PATH
    /usr/include
    )

NO_DEFAULT_PATH should be at the end of the list of arguments, so the 
directory (directories) coming after it are probably ignored.

If you remove NAMES and PATHS you get probably the old "signature" of 
FIND_PATH, which is more or less just 
FIND_PATH(VAR <filename> <path1> ... <pathN>)
so that NO_DEFAULT_PATH is interpreted as a directory and so the default paths 
are searched.
