[CMake] Two commands for a single dependency

[James Bigler]

Is it possible to run two commands and have them execute in order for a 
given rule.  Here is what I want to do in a makefile:

default: child.o

child-copy.d:
	touch child-copy.d

include child-copy.d

child.o: $(CXXPATH)/child.cc
	g++ -c $< -o $@ -MD
	cp child.d child-copy.d

Thanks,
James
