android压缩图片_linux环境手动编译全平台jpeg-8

目的：
------------------------------------------------------------------------------------------------------------------------------------------------
1. 傻瓜式linux编译操作
2. 编译android studio 需要的所有平台 （'armeabi','armeabi-v7a','arm64-v8a','mips','mips64','x86','x86_64'）
3. 编译得到的.a文件静态链接库, 同 .so文件动态链接库（用法没有区别）

   android studio cmake 编译配置信息
   #lib-image-jpeg.a
   add_library(image-jpeg STATIC IMPORTED)
   set_target_properties( image-jpeg
                           PROPERTIES IMPORTED_LOCATION
                           ${distribution_DIR}/${ANDROID_ABI}/libimage-jpeg.a )

------------------------------------------------------------------------------------------------------------------------------------------------

编译方法（linux环境）：
------------------------------------------------------------------------------------------------------------------------------------------------
1.  将压缩包里面的config文件移动到jpeg8c文件夹里面
2.  控制台输入命令：
2.1 sh config
2.2 make
2.3 make install
2.4 make distclean
