android集成opencv和dlib报错

最近项目需要加入人脸识别, 于是加入opencv和dlib来实现 ,参考网上集成时报错
cmakelists代码

cmake_minimum_required(VERSION 3.4.1)

set(NATIVE_DIR ${CMAKE_SOURCE_DIR}/src/main/cpp)

include(${NATIVE_DIR}/dlib/cmake)
include_directories(${NATIVE_DIR}/opencv/jni/include)
add_library(
        libopencv_java3
        SHARED
        IMPORTED)
set_target_properties(
        libopencv_java3
        PROPERTIES
        IMPORTED_LOCATION
        ${NATIVE_DIR}/opencv/libs/${ANDROID_ABI}/libopencv_java3.so)

AUX_SOURCE_DIRECTORY(${NATIVE_DIR}/jni_common SRC_LIST)
add_library( # Sets the name of the library.
        native-lib
        SHARED
        ${SRC_LIST}
        src/main/cpp/face_detector.h
        src/main/cpp/face_detector.cpp
        src/main/cpp/native-lib.cpp)

find_library( # Sets the name of the path variable.
        log-lib
        log)


target_link_libraries( # Specifies the target library.
        native-lib
        dlib
        libopencv_java3
        jnigraphics
        # Links the target library to the log library
        # included in the NDK.
        ${log-lib})

set(CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE} -s -O3 -Wall")
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -s -O3 -Wall")

这是报错信息

报的是opencv的 libopencv_java3.so 库在原生ndk的libnative-lib.so没有找到对应的规则，应该是版本不合适，建议切换版本试试。

看看这个对不对，
