Linux makefile Multi-Directory authoring

A project on hand, need to write a project makefile

Multi-Directory structure:

csource/

├──common
│└──sqlite3
├──inc
│├──curl
│├──lua
│└──protection
├──lib
│├──arm
│└──linux
├──obj
├──out
│├──arm
│└──linux
├──src

source directory src, output directory out,include Directory inc, Input link library directory lib, common static functions and Sqlite3 Catalogue Common

Makefile as follows:
