So this would be this (for the last rule)?

ADD_CUSTOM_COMMAND(OUTPUT child.o
                    COMMAND g++
                    ARGS -c child.cc -o child.o -MD
                    DEPENDS ${CXXPATH}/child.cc
                    )

ADD_CUSTOM_COMMAND(OUTPUT child.o
                    COMMAND cp
                    ARGS child.d child-copy.d
                    DEPENDS ${CXXPATH}/child.cc
                    )

Thanks,
