For all files in $(OBJS1), all these static pattern rules apply,
not just the one rule you want. I'd use target-specific variable
values:
$(OBJS1): CFLAGS := CFLAGS1
$(OBJS1): CXXFLAGS := CXXFLAGS1
$(OBJS2): CFLAGS := CFLAGS2
$(OBJS2): CXXFLAGS := CXXFLAGS2
%.o: %.c
$(CC) -c $(CFLAGS) $< -o$@
%.o: %.cpp
$(CXX) -c $(CXXFLAGS) $< -o$@
