CGAL 无法识别类型

对于我的论文项目，我依赖于另一个学生一年前写的一堆CGAL代码。不幸的是，由于出现错误，我无法编译代码。这些错误可能不是以前的学生经历过的，所以它们可能与我的设置比代码本身更相关，但我不知道直接原因是什么。

错误在文件CCBSegmentCalculator.h中。代码如下：

#pragma once
#include "bezier_arrangement.h"
//Circulates around a PL_Arrrangement CCB, visiting the points between the segments that make up the CCB
//  (so smaller-scale than the build-in iterator that only visits the PL_Arrangement vertices)
// --- Could be used in more places than it is now, e.g., in the SVGHandler
class CCBSegmentCirculator
{
public:
CCBSegmentCirculator(PL_Arrangement::Ccb_halfedge_const_circulator ccbCirculator);
const CCBSegmentCirculator& next();
PL_Point operator*();
PL_Point get(); // same as operator*
bool operator==(const CCBSegmentCirculator &other) const;
private:

const PL_Arrangement::Ccb_halfedge_const_circulator halfedgesBegin;
PL_Arrangement::Ccb_halfedge_const_circulator halfedge;
//Depending on this boolean ...
bool forward;
//... we are either using these forward iterators ...
// -> in which case the 'current' point is segment.source
Polyline::Segment_const_iterator segment;
Polyline::Segment_const_iterator segmentEnd;
//... or these reverse iterators
// -> in which case the 'current' point is segmentReverse.target
Polyline::Segment_const_reverse_iterator segmentReverse;
Polyline::Segment_const_reverse_iterator segmentReverseEnd;
void initHalfedge();
};

文件"bezier_arrangement.h"具有以下代码：

我遇到的错误与以下事实有关：CGAL认为定义的Polyline类型没有成员Segment_const_iterator，或者根本无法正确识别该类型。我不确定，因为它被翻译成内部CGAL类型。我得到的错误是：

Error   C2039   'Segment_const_iterator': is not a member of 'CGAL::internal::Polycurve_2<SubcurveType_2,PointType_2>'  CurvedNonograms c:usersdemeessiasdocuments1. studie.masterthesiscurvednonograms-codecurvednonogramscurvednonogramsccbsegmentcirculator.h  39

对于包含segment、segmentEnd、segmentReverse和segmentReverseEnd的定义的行重复。

根据文档，Curve_2应该有一个Segment_const_iterator的定义。

再一次，错误可能不在代码本身，而是在我的CGAL构建/链接中。重新安装CGAL并没有帮助，我很确定我已经在相关的地方链接了它，但这部分构建软件并不是我的强项，所以我可能不知道所有相关的地方。

编辑：输出中给出的第一个错误是：

这与上面显示的代码文件不同，因为代码中有更多错误，但所有错误似乎都源于类似的问题。还有一些形式的警告：

将CCBSegmentCalculator.h添加到另一个项目中只进行编译会出现以下错误：
