[bug #51306] Checking programming possibilities around “MAKECMDGOALS”

[Paul D. Smith]

Update of bug #51306 (project make):

              Item Group:                     Bug => Documentation

Follow-up Comment #1:

The same way you'd check for a word in any other list of words, in GNU make:


sources = foo.c bar.c

ifeq (,$(filter clean,$(MAKECMDGOALS)))
include $(sources:.c=.d)
endif


will only include the files if "clean" doesn't appear anywhere in
MAKECMDGOALS.

However, I'm not sure that this is the correct behavior.  Suppose someone used
"make clean all"; now none of the dependency files will be included for the
"all" target.

I'll leave this open as a Doc bug to determine whether the example needs to be
reworked.
