I’m trying to setup the following rules

%.o : %.c
ifeq ( $(findstring _zu, $<),_zu )
echo with zu
else
echo without zu
endif

The test always success (with zu) whatever the c filename is. Any pointers?

The “ifeq” is expanded at the time the Makefile is read - way too early
for the $< variable to set properly. Try this:

CMD_zu=echo $< with zu
CMD=echo $< without zu

%.o : %.c
$(CMD$(findstring _zu, $<))
