Как мне включить dlib как часть моего проекта в CLion?

Текущая настройка C ++:

  • Clion IDE
  • dlib

Я запускаю один из примеров C ++, предоставленных dlib

#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;
}
}

Вот так сейчас выглядит мой текущий файл CMakeList.txt

> 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})

Я попытался использовать пример файла CMakeList.txt, но он не работал должным образом. Итак, как мне добавить dlib в путь моего проекта и правильно настроить файл CMakeList?

Решение

Вам нужно собрать dlib следующим образом:

  1. cd dlib
  2. mkdir build -> cd build
  3. чмк ..
  4. делать
  5. sudo make install
  6. sudo ldconfig -> обновит кеш общей библиотеки

это создаст файлы .so и dlibConfig.cmake, которые будут распознаваться CLion IDE.

Другие решения

Я полагаю, вы собрали dlib на вашем компьютере.
Затем добавьте два утверждения ниже в ваш CMakeLists.txt, это будет работать.

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