Make - two target produced by one recipe
Suppose executable X produces files A and B from nothing, Y produces C from A, Z produces D from B, and my final goal is to produce C and D. I wrote the following makefile:
.PHONY: all
all: C D
C: AY A
D: BZ B
A B:X
This makefile seems to reflect all dependencies, as it should be. However if I delete A and B, then X will be executed twice.
How do I fix this file so that it still reflects all dependencies, but in any case executes X only once?
Thanks in advance
