Android ndk cmake编译libyuv

1. 下载源码:https://chromium.googlesource.com/libyuv/libyuv
2. 将libyuv源码解压复制到src/main/cpp目录下(包括cmakeList.txt和Android.mk)

3. 根据需要注释libyuv的cmakeList.txt里面的一些内容

# CMakeLists for libyuv

# Run with -DTEST=ON to build unit tests

4. 编写自己的cmakeList文件

cmake_minimum_required(VERSION 3.4.1)


include_directories(src/main/cpp/libyuv/include)

add_subdirectory(src/main/cpp/libyuv)

add_library( # Sets the name of the library.
        native-lib
        SHARED
        src/main/cpp/native-lib.cpp)


target_link_libraries(
        native-lib
        log
        yuv)
