linux - cmake 错误 : opencv2/opencv. hpp:opencv2/opencv.hpp:No such file or directory

Question

我正在用 cmake 编译 opencv 程序。 代码如下:

显示图像.cpp:

#include <stdio.h>
#include <opencv2/opencv.hpp>
using namespace cv;
int main(int argc, char** argv )
{
    if ( argc != 2 )
    {
        printf("usage: DisplayImage.out <Image_Path>\n");
        return -1;
    }

    Mat image;
    image = imread( argv[1], 1 );

    if ( !image.data )
    {
        printf("No image data \n");
        return -1;
    }
    namedWindow("Display Image", WINDOW_AUTOSIZE );
    imshow("Display Image", image);

    waitKey(0);

    return 0;
}

CMakeLists.txt:

cmake_minimum_required(VERSION 2.8)

project( DisplayImage )

set(OpenCV_DIR /home/lmk/opencv-3.1.0/release)

include_directories( ${OpenCV_INCLUDE_DIRS} )

add_executable( DisplayImage DisplayImage.cpp )

target_link_libraries( DisplayImage ${OpenCV_LIBS} )

我将 DisplayImage.cpp 和 CMakeLists.txt 放在我个人主文件夹中名为 test 的文件夹中，即 /home/lmk/test/。 然后我使用命令行:

lmk@lmk-virtual-machine:~/test$ mkdir build
lmk@lmk-virtual-machine:~/test$ cd build
lmk@lmk-virtual-machine:~/test/build$ cmake ..

哪个给我:

但是当我使用时:

Scanning dependencies of target DisplayImage
[100%] Building CXX object CMakeFiles/DisplayImage.dir/DisplayImage.cpp.o
/home/lmk/test/DisplayImage.cpp:2:30: fatal eror：opencv2/opencv.hpp：No such file or directory
compilation terminated.

make[1]: * [CMakeFiles/DisplayImage.dir/all] Error 2
make: *** [all] Error 1

你知道为什么吗？ 我在 VM 中的 ubuntu 14.04 终端中使用 opencv 3.1.0 和 cmake 2.8.12.2!

Answer 1

为什么不使用“典型”方式，使用 find_package()？
