Question

当前的C ++设置是：

Clion IDE
dlib

我正在运行dlib提供的一个C ++示例

#include <dlib/gui_widgets.h>
#include <dlib/image_io.h>
#include <dlib/image_transforms.h>
#include <fstream>


using namespace std;
using namespace dlib;

//  ----------------------------------------------------------------------------

int main(int argc, char** argv)
{
    try
    {
        // make sure the user entered an argument to this program
        if (argc != 2)
        {
            cout << "error, you have to enter a BMP file as an argument to this program" << endl;
            return 1;
        }

        // Here we declare an image object that can store rgb_pixels.  Note that in 
        // dlib there is no explicit image object, just a 2D array and
        // various pixel types.  
        array2d<rgb_pixel> img;

        // Now load the image file into our image.  If something is wrong then
        // load_image() will throw an exception.  Also, if you linked with libpng
        // and libjpeg then load_image() can load PNG and JPEG files in addition
        // to BMP files.
        load_image(img, argv[1]);


        // Now let's use some image functions.  First let's blur the image a little.
        array2d<unsigned char> blurred_img;
        gaussian_blur(img, blurred_img); 

        // Now find the horizontal and vertical gradient images.
        array2d<short> horz_gradient, vert_gradient;
        array2d<unsigned char> edge_image;
        sobel_edge_detector(blurred_img, horz_gradient, vert_gradient);

        // now we do the non-maximum edge suppression step so that our edges are nice and thin
        suppress_non_maximum_edges(horz_gradient, vert_gradient, edge_image); 

        // Now we would like to see what our images look like.  So let's use a 
        // window to display them on the screen.  (Note that you can zoom into 
        // the window by holding CTRL and scrolling the mouse wheel)
        image_window my_window(edge_image, "Normal Edge Image");

        // We can also easily display the edge_image as a heatmap or using the jet color
        // scheme like so.
        image_window win_hot(heatmap(edge_image));
        image_window win_jet(jet(edge_image));

        // also make a window to display the original image
        image_window my_window2(img, "Original Image");

        // Sometimes you want to get input from the user about which pixels are important
        // for some task.  You can do this easily by trapping user clicks as shown below.
        // This loop executes every time the user double clicks on some image pixel and it
        // will terminate once the user closes the window.
        point p;
        while (my_window.get_next_double_click(p))
        {
            cout << "User double clicked on pixel:         " << p << endl;
            cout << "edge pixel value at this location is: " << (int)edge_image[p.y()][p.x()] << endl;
        }

        // wait until the user closes the windows before we let the program 
        // terminate.
        win_hot.wait_until_closed();
        my_window2.wait_until_closed();


        // Finally, note that you can access the elements of an image using the normal [row][column]
        // operator like so:
        cout << horz_gradient[0][3] << endl;
        cout << "number of rows in image:    " << horz_gradient.nr() << endl;
        cout << "number of columns in image: " << horz_gradient.nc() << endl;
    }
    catch (exception& e)
    {
        cout << "exception thrown: " << e.what() << endl;
    }
}

这就是我当前的CMakeList.txt文件现在的样子

> cmake_minimum_required(VERSION 3.2)
project(Project-Hurst)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES src/main.cpp)
add_executable(Project-Hurst ${SOURCE_FILES})

我尝试使用示例CMakeList.txt文件，但它无法正常工作。那么如何将dlib添加到我的项目路径中，并正确设置CMakeList文件？

Answer 1

您需要按以下方式构建dlib：

cd dlib
mkdir build - ＆gt; cd build
cmake ..
使
sudo make install
sudo ldconfig - ＆gt;将更新共享库缓存

这将创建将由CLion IDE识别的.so和dlibConfig.cmake文件。

Answer 2

我想你已经在你的计算机上编译了dlib。然后，在CMakeLists.txt中添加以下两个语句，它将起作用。

find_package(dlib REQUIRED)
target_link_libraries(${PROJECT_NAME} ${dlib_LIBS})

Answer 3

如果您正在寻找Windows操作系统的答案。然后，您可以按照以下简单步骤进行操作。

安装C ++ 11编译器（支持C ++ 11或更高版本的编译器）。我建议使用TDM-GCC-64 Compiler
在安装编译器后，将路径变量 C：\ TDM-GCC-64 \ bin 设置为您的操作系统。
下一步下载dlib文件夹并将其解压缩到 C：\ dlib 。现在，请按照下列步骤。假设您位于命令提示符下的 C：\ 位置。

cd dlib
mkdir构建
cd构建
cmake .. -G“ MinGW Makefiles”
mingw32-make
mingw32-make install

接下来将 dlibConfig.cmake 和 dlib.cmake 文件复制到 cmake-build-debug 文件夹中。该文件夹将位于您的CLion C ++项目中。
现在检查 dlibConfig.cmake 文件，并在发现 include（C：/ Program Files（x86）/ Project / include / dlib / cmake_utils / use_cpp_11.cmake），然后将其转换为 include（“ C：/ Program Files（x86）/Project/include/dlib/cmake_utils/use_cpp_11.cmake”）。

在您的 CMakeList.txt 文件中添加以下几行。

include_directories（$ {dlib_LIBRARIES}）
include_directories（$ {dlib_LIBS}）
include_directories（$ {dlib_INCLUDE_DIRS}）
target_link_libraries（$ {PROJECT_NAME} $ {dlib_LIBS}）

现在，您可以在CLion中使用dlib库了。

如何在dion中包含dlib作为我项目的一部分？
