博客作者更新了之前的makefile，以解决多目录项目中C和C++混合编译的问题，增加了忽略列表功能，并修复了自动依赖时的路径问题，确保模式规则与依赖信息匹配。

在之前的博客里，给出了一份makefile，但是在使用过程中发现一些问题，因此对其进行了更新，之前的文章地址如下，感兴趣的可以看看：

更新的makefile，增加了一份忽略列表，可以将不想编译的文件加到里面，另外就是支持C和C++的混合编译。

更新：

2019.03.24 之前的版本自动依赖是有问题的，主要是由于如果依赖包含了路径，则对应的模式规则也需要包含路径，否则根据模式规则生成文件时，没有参考依赖信息。更新对该问题进行了修复，另外将部分变量名改为与make内建变量名一致。
