# - A smarter replacement for list(REMOVE_DUPLICATES) for library lists
#
# Note that, in the case of cyclic link dependencies, you _do_ actually need
# a library in a list multiple times. So, only use this function when you know
# that the dependency graph is acyclic.
#
# clean_library_list(<listvar> [<additional list items>...]) - where
# listvar is the name of a destination variable, and also possibly a source, and
# it is followed by any number (including 0) of additional libraries to append
# to the list before processing.
#
# Removes duplicates from the list, leaving only the last instance, while
# preserving the meaning of the "optimized", "debug", and "general" labeling.
# (Libraries listed as general are listed in the result instead as optimized and
# debug)
#
# Requires CMake 2.6 or newer (uses the 'function' command)
