本文介绍了如何在没有预装opencv的情况下，配置opencv路径以编译NCNN的示例程序。需要修改ncnn/example/CMakeList.txt文件，添加opencv2的路径并链接对应的库。编译过程包括在ncnn根目录打开CMakeList.txt，放开add_subdirectory(examples)，然后在build目录执行cmake和make。

NCNN例程序只支持opencv2,不支持opencv3。ncnn和opencv的路径根据自己情况修改。

在没安装opencv情况下，自己配置opencv路径方式编译例程

打开ncnn/example/CMakeList.txt文件；

根据自己的opencv2的路径添加如下内容：

cmake_minimum_required(VERSION 3.10)
set(OPENCV_PATH /home/pytorch/mywork/ncnn/opencv-2.4.13.6)
include_directories(${OPENCV_PATH}/modules/objdetect/include)
include_directories(${OPENCV_PATH}/modules/highgui/include)
include_directories(${OPENCV_PATH}/modules/imgproc/include)
include_directories(${OPENCV_PATH}/modules/core/include)

set(OpenCV_LIBS ${OPENCV_PATH}/build/lib)

LINK_DIRECTORIES(${OpenCV_LIBS})

#ifind_package(OpenCV QUIET COMPONENTS core highgui imgproc imgcodecs)
#if(NOT OpenCV_FOUND)
# find_package(OpenCV REQUIRED COMPONENTS core highgui imgproc)
#endif()

set(NCNN_EXAMPLE_LINK_LIBRARIES ncnn ${OpenCV_LIBS}/libopencv_core.so ${OpenCV_LIBS}/libopencv_highgui.so ${OpenCV_LIBS}/libopencv_imgproc.so)

回到/ncnn/，打开CMakeList.txt把add_subdirectory(examples)放开。

cd build

cmake ..

make -j4

完成编译
