Swift & C (Part 4: makefile with swift and c)

[nonocast]

Version: Swift 5.6, macOS 12.3, Xcode 11

重新整理了swift调用librtmp

• 将librtmp放到项目直接编译
• 参考librtmp目录结构，2个makefile
• 增加了googletest

目录结构:

• rtmpr
  • librtmpr/
    • Makefile
  • bridge.h
  • app.swift
  • Makefile

rtmpr/Makefile

all: librtmpr/librtmpr.a app
