When, in the makeBaseApp-generated example, in exampleApp/src/Makefile I 
change

PROD_IOC = example

to

PROD_IOC_vxWorks = example

then the product no longer depends on neither sources nor libraries. I 
can do e.g.

aragon: .../work/test > make -s
[...make builds everything...]
aragon: .../work/test > touch exampleApp/src/sncProgram.st 
aragon: .../work/test > make -s
[...silence, nothing is done...]
aragon: .../work/test > 

I suspect that the problem is in the generated MakefileInclude. Here is 
a snippet:

ifeq ($(filter example,$(TESTPROD) $(PROD)),example)
ifeq (,$(strip $(example_OBJS) $(PRODUCT_OBJS)))
example_OBJS+=example$(OBJ)
endif
example_RESS+=$(addsuffix $(RES),$(basename $(example_RCS)))
example_OBJSNAME+=$(addsuffix $(OBJ),$(basename $(example_OBJS)))
example_DEPLIBS=$(foreach lib, $(example_LDLIBS),\
 $(firstword $(wildcard $(addsuffix /$(LIB_PREFIX)$(lib).*,\
 $($(lib)_DIR) $(SHRLIB_SEARCH_DIRS)))\
 $(addsuffix /$(LIB_PREFIX)$(lib)$(LIB_SUFFIX),\
 $(firstword $($(lib)_DIR) $(SHRLIB_SEARCH_DIRS))/)))
example$(EXE): $(example_OBJSNAME) $(example_RESS) $(example_DEPLIBS)
endif

So example will depend on its libraries only if mentioned in either PROD 
or TESTPROD, but not if mentioned only in e.g. PROD_IOC_vxWorks.

I have no idea what the outer ifeq...endif is good for; maybe it could 
be removed?

Would be nice if this could be fixed before 3.14.9 comes out.

Cheers
Ben
