在C++控制台项目中调用CGAL

CGAL的安装教程详细：https://www.cnblogs.com/ShawBlack/p/17000087.html

对于如何在项目中调用CGAL，跟着下面的流程走就好

 

1.用VS新建C++控制台项目

 

2.配置项目依赖项

(1).选中项目右键-属性，进入项目属性页。

(2).C/C++ - 常规 -附加包含目录：

• • C:\dev\CGAL-5.2.1\include
  • C:\dev\CGAL-5.2.1\auxiliary\gmp\include
  • C:\local\boost_1_71_0

(3).链接器->输入->附加依赖项：

• • C:\dev\CGAL-5.2.1\auxiliary\gmp\lib\libgmp-10.lib
  • C:\dev\CGAL-5.2.1\auxiliary\gmp\lib\libmpfr-4.lib

3.拷贝下面代码

#include <iostream>
#include <CGAL/Simple_cartesian.h>
typedef CGAL::Simple_cartesian<double> Kernel;
typedef Kernel::Point_2 Point_2;
typedef Kernel::Segment_2 Segment_2;
int main()
{
  Point_2 p(1,1), q(10,10);
  std::cout << "p = " << p << std::endl;
  std::cout << "q = " << q.x() << " " << q.y() << std::endl;
  std::cout << "sqdist(p,q) = "
            << CGAL::squared_distance(p,q) << std::endl;
  Segment_2 s(p,q);
  Point_2 m(5, 9);
  std::cout << "m = " << m << std::endl;
  std::cout << "sqdist(Segment_2(p,q), m) = "
            << CGAL::squared_distance(s,m) << std::endl;
  std::cout << "p, q, and m ";
  switch (CGAL::orientation(p,q,m)){
  case CGAL::COLLINEAR:
    std::cout << "are collinear\n";
    break;
  case CGAL::LEFT_TURN:
    std::cout << "make a left turn\n";
    break;
  case CGAL::RIGHT_TURN:
    std::cout << "make a right turn\n";
    break;
  }
  std::cout << " midpoint(p,q) = " << CGAL::midpoint(p,q) << std::endl;
  return 0;
}

4.编译生成项目

 

 5.enjoy~
