Dlib在Visual Studio 2017上的编译和配置

此教程根据官网整理。

工具：
CMake + Visual Studio 2017 + Win 10

编译

1.以管理员身份打开命令行；
2.Lz路径：F:\GitHub\dlib-19.16，命令行输入：

>F:
>cd GitHub\dlib-19.16\examples
>mkdir build
>cd build
>cmake ..
>cmake --build . --config Release

3.默认编译32位，编译64位参考：https://blog.csdn.net/xingchenbingbuyu/article/details/53236541
4.等待编译结束即可；

配置

1.新建文件夹lib，将编译后的dlib19.16.0_release_32bit_msvc1914.lib(F:\GitHub\dlib-19.16\examples\build\dlib_build\Release)复制到lib(F:\GitHub\dlib-19.16\lib)下；
2.新建Win32控制台程序；
3.配置环境变量，打开属性页：

1.配置属性\VC++ 目录\库目录：F:\GitHub\dlib-19.16\lib;
2.配置属性\C/C++\常规\附加包含目录：F:\GitHub\dlib-19.16;
3.配置属性\链接器\输入\附加依赖项：dlib19.16.0_release_32bit_msvc1914.lib

4.运行以下程序：

#include <dlib/gui_widgets.h>
#include <dlib/image_transforms.h>
#include <cmath>

using namespace dlib;
using namespace std;

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

int main()
{
	// Let's make a point cloud that looks like a 3D spiral.
	std::vector<perspective_window::overlay_dot> points;
	dlib::rand rnd;
	for (double i = 0; i < 20; i += 0.001)
	{
		// Get a point on a spiral
		dlib::vector<double> val(sin(i), cos(i), i / 4);

		// Now add some random noise to it
		dlib::vector<double> temp(rnd.get_random_gaussian(),
			rnd.get_random_gaussian(),
			rnd.get_random_gaussian());
		val += temp / 20;

		// Pick a color based on how far we are along the spiral
		rgb_pixel color = colormap_jet(i, 0, 20);

		// And add the point to the list of points we will display
		points.push_back(perspective_window::overlay_dot(val, color));
	}

	// Now finally display the point cloud.
	perspective_window win;
	win.set_title("perspective_window 3D point cloud");
	win.add_overlay(points);
	win.wait_until_closed();
}

5.运行结果：
