前言：研究别人代码，发现google现在推荐并在Android Studio 支持cmkelist 放弃mk方式。比较蛋疼，但是也是学习的一个方式。一步步积累如何使用Cmakelist

对比

• LOCAL_MODULE,LOCAL_SRC_FILES
  mk 写法,整个mk文件我拆分两部分，主要是为了学习写法
  前部分

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := KRoom
LOCAL_SRC_FILES := KRoom.cpp \
                   ./manager/JniManager.cpp \
                   ./manager/AVMediaPlayer.cpp \
                   ./manager/AudioManager.cpp \
                   ./manager/VideoManager.cpp \
                   ./opengl/NativeRender.cpp \
                   ./common/Buffer.cpp \
                   ./common/Mutex.cpp \
                   ./common/Frame.cpp \
                   ./common/FrameMap.cpp \

                   ./common/FrameSubMap.cpp \
                   ./common/util.cpp \
                   ./stream/StreamDecoder.cpp \
                   ./stream/StreamPlayer.cpp    \
                   ./vedio/VideoDecoder.cpp   \
                   ./shellmp4/FileControl.cpp   \
                   ./shellmp4/HttpShellInterface.cpp    \
                   ./shellmp4/MakeAACHead.cpp   \
                   ./shellmp4/MP4Control.cpp    \
                   ./shellmp4/MP4Handler.cpp    \
                   ./shellmp4/ShellMain.cpp \
                   ./shellmp4/ShellMp4.cpp  \
                   ./shellmp4/GetData.cpp   \
                   check.c \
                   md5.c

LOCAL_STATIC_LIBRARIES  := avcodec avutil x264 macdecoder reverb

LOCAL_C_INCLUDES := \
        $(LOCAL_PATH)/ffmpeg/   \

转换成cmakelist写法超级简单

add_library( # Sets the name of the library.
             KRoom

             # Sets the library as a shared library.
             SHARED

             # Provides a relative path to your source file(s).
