通用makefile模板，跨平台，适合大小工程

跨平台的通用makefile模板

同时兼容C, C++, ASM文件编译
支持MCU嵌入式, windows, linux平台的gcc/g++编译
支持更新头文件后, 自动编译依赖头文件的相关文件

测试环境：
  Linux：vscode + gcc
  windows：mingw64 + bash (git自带)
    由于含LINUX命令行, windows下使用git自带的bash命令行工具(此工具包含多数常用LINUX命令)

本模板包含：mkenv.mk(和运行平台相关的配置) + Makefile(与平台无关的工程配置)

修改mkenv.mk：
  编译不同平台的目标, 修改编译环境

修改makefile：
  添加头文件路径, 库, 源文件, 宏定义

如有需要完善的地方可留言
