C/C++的通用Makefile模板

本文在 http://sourceforge.net/projects/gcmakefile/ 的成果上改进得来。 主要修改如下: 1.去掉了说明部分,使得模版更简洁; 模版本身已经具备自说明特性。 2.去掉自动生成目标名称部分; 目标名称必须指定。 3.%.d文件替换为.%.d文件, 即隐藏了依赖文件, 使得源代码目录编译后看起来更简洁. 4.如果不指定源代码目录(SRCDIRS), 则自动搜索当前目录下的所有子目录, 而不仅仅只是当前目录. 这个模版最大特点就是可以适应各种不同的应用, 基本上拿来就可以用, 改动很少; 而且自适应增删源文件, 自适应多级目录结构, 自动检查头文件依赖.
