[我先运行make clean，然后运行make DEBUG=1，它会正确编译我的文件。如果我想添加另一个参数，我应该可以键入make DEBUG=1 SIMULATE=1，但它不会与新的C_FLAG重新编译。
这是在makefile中创建目标文件的位置。当我指定%.c.o: $(C_FLAGS)时，它仍然不会重新编译。

我希望在使用新参数时重新编译。
我认为此Makefile中最简单的方法是为您关心的每个开关配置使用不同的OUTPUT_DIRECTORY。您可以自己制作各种变体或进行概括，例如：
OUTPUT_DIRECTORY = $(shell echo $(CFLAGS) $(CXXFLAGS) | sha1sum | cut -f1 -d\ )

可能需要进行微调，因为扩展时会解析$(OUTPUT_DIRECTORY)（因此，sha1sum被计算了很多次-费用很高，但是实际解决方案取决于确切地设置变量的位置。
