I think this is just a misunderstanding and not related to CMake. Make --question mode always returns a 1 if the target is PHONY because these targets are always out of date. The Makefiles generated by CMake use a top level PHONY target (and other PHONY targets as well)
zzz@i7-lab:~/temp/bldlibvnc$ make -q CMakeFiles/vncserver.dir/libvncserver/zrleoutstream.c.o zzz@i7-lab:~/temp/bldlibvnc$ echo $? 0 zzz@i7-lab:~/temp/bldlibvnc$ make -q zzz@i7-lab:~/temp/bldlibvnc$ echo $? 1 OR zzz@i7-lab:~/temp/bldlibvnc$ make -q vncclient zzz@i7-lab:~/temp/bldlibvnc$ echo $? 1 zzz@i7-lab:~/temp/bldlibvnc$ make -q libvncclient.so zzz@i7-lab:~/temp/bldlibvnc$ echo $? 0 So you'll need to discern the actual target you want to check.
