You've defined LDFLAGS as:
LDFLAGS = -L$(INCLUDE_SEAL_LIB) -llibseal.a -lpthread

I mean it should be defined as:
LDFLAGS = -L$(INCLUDE_SEAL_LIB) -lseal -lpthread

Also, AFAIK, the command should be specified in one line, like that:
seal_diff_cpp.so: seal_diff_cpp.o
        $(CXX) -Wl,--no-undefined -shared -o seal_diff_cpp.so
seal_diff_cpp.o $(LDFLAGS)
