For example, you coud use this Makefile.am instead:

--- snip ---
noinst_PROGRAMS = target
target_SOURCES = main.c

if WITH_CASE1
target_SOURCES += case1.c
endif

if WITH_CASE2
target_SOURCES += case2.c
endif
--- snip ---

With the above, there is no need to set target_LDADD or
target_DEPENDENCIES.

Does that work for you?  If no, there is also the possibility to do
something like this:

--- snip ---
if WITH_CASE1
DEPS1=case1.lo
else
DEPS1=
endif

if WITH_CASE2
DEPS2=
else
DEPS2=case2.lo
endif

noinst_PROGRAMS=target

target_SOURCES = main.c
EXTRA_target_SOURCES = case1.c case2.c
target_LDADD= $(DEPS1) $(DEPS2)
--- snip ---

But you would still not need to set target_DEPENDENCIES: automake is
smart enough to figure it out itself.

Cheers,
Ralf
