Thanks.  Please try this code instead:

    # If we ran before and reported multiple configurations then PYTHON_LIBRARY
    # is a list "optimized;PYTHON_LIBRARY;debug;PYTHON_LIBRARY_DEBUG".  Extract
    # the original value so we can re-construct the list properly later.
    if(";${PYTHON_LIBRARY};" MATCHES ";optimized;([^;]+);")
      set(PYTHON_LIBRARY "${CMAKE_MATCH_1}")
    endif()

Thanks,
