CMakeList编译报错ninja: error: missing and no known rule to make it解决方法

Android NDK开发引用第三方库CMakeList.txt编译报错：

ninja: error: '/XXX/NDKApplication/app/src/main/cpp/src/main/cpp/armeabi-v7a/libavcodec.so',

needed by '/XXX/NDKApplication/app/build/intermediates/cmake/debug/obj/armeabi-v7a/libhf_code.so', missing and no known rule to make it

原因是CMakeList.txt 里的配置有误，我用的版本是3.10.2

原因一：文件路径或文件名配置错误

cmake_minimum_required(VERSION 3.10.2)
add_library( # Sets the name of the library.
        hf_code
        SHARED
        native_test.cpp #这里路径或文件名配置有误
        )

原因二：target_link_libraries 链接第三方库没有使用${}包起来

add_library( swscale-5
        SHARED
        IMPORTED)
set_target_properties( swscale-5
        PROPERTIES IMPORTED_LOCATION
        ${CMAKE_SOURCE_DIR}/src/main/cpp/armeabi-v7a/libswscale.so)


target_link_libraries(

     
        ${swscale-5} #链接第三方库需要${}

        ${log-lib} )

附一份导入了FFmpeg库的完整CMakeList.txt
