前言
本文为了记录自己在实习的过程中，学习到的有关OCCT开源项目的搭建工作，旨在教会小白从0开始下载开源项目及环境搭配，以及如何添加自定义测试内容，最终结果展示如下：
1、项目所需工具下载
本项目共需要使用四个工具，分别是OCCT开源代码，QT环境，CMake构建工具，VS2019，版本也会介绍。我会把CMake、VS2019、第三方库放到Github链接里https://github.com/shadow0fiend/OCCT-Project，OCCT源码以及QT环境需要自己下载
其中下载链接如下：
OCCT（7.8或7.6或7.5皆可）：Download - Open CASCADE Technology
第三方库及VS2019：GitHub - shadow0fiend/OCCT-Project: 构建OCCT项目
QT工具（5.14.2）：Index of /archive/qt
CMake（3.29.3）：Download CMake
其中安装过程如下：
OCCT：下载64位的压缩包，解压到本地即可。
QT：对于新手，建议在勾选下载内容的时候全部选上（简单粗暴，不会缺少东西）
详情下载过程请参考链接：Qt5.14.2安装、配置及测试（Win10）-CSDN博客
CMake：无脑下一步即可
详情下载过程请参考链接：Windows下Cmake安装步骤详解（图文）_windows终端安装cmake-CSDN博客
安装完以后，本地应该有以下几个内容，注意检查cmake-gui、OCCT源码、编译用的三方库（下图product）、QT环境、VS2019
2、使用CMake编译源码
步骤1：在OCCT源码中建立一个build文件夹，用于存放编译后的文件
步骤2：打开CMake-gui，第一个位置填入OCCT源码文件夹的路径，第二个位置填入刚才创建好的build文件夹的路径
步骤3：点击configure，选择配置vs2019，x64，点击finish
步骤4：
第一步，在3RDPARTY_DIR这一行，填入第三方库文件的路径，也就是product的路径。
第二步，然后勾选上BUILD_SAMPLES_QT这一行。
第三步点击config。
步骤5：
第一步，修改QT路径，这个Qt5.14.2是安装完QT以后的文件夹，自行在里面找对应的文件（如果没有找到，应该是QT安装下载的时候，有的选项没有勾上）
第二步，改完以后点击config，点击generate，点击open project
步骤7：cmake配置完毕，最终配置结果如下所示
3、配置项目运行环境
生成的项目如下所示（如果没有勾选QT，那么编译完成以后的项目是不包含Samples文件的，只有非常简陋的可视化界面）：
步骤1：鼠标右击OCCTOverview，设置OCCTOverview为启动项。
步骤2：鼠标右击OCCTOverview，依次找到属性、Debugging、environment，将以下内容粘贴进去，这是配置项目环境变量的。注意：需要将路径修改为自己电脑的路径。
配置解释：
CASROOT需要配置OCCT源码文件夹
CSF_OCCT都是OCCT源码文件夹里面的文件
最后一行是配置QT的bin，QT的platforms，第三方库文件freetype，freeimage
CASROOT=E:\cpp\code\OCCT\OCCT-7_8_0CSF_FPE=0CSF_OCCTResourcePath=E:\cpp\code\OCCT\OCCT-7_8_0/srcCSF_OCCTDataPath=E:\cpp\code\OCCT\OCCT-7_8_0/dataCSF_OCCTSamplesPath=E:\cpp\code\OCCT\OCCT-7_8_0/samplesCSF_OCCTTestsPath=E:\cpp\code\OCCT\OCCT-7_8_0/testsCSF_OCCTDocPath=E:\cpp\code\OCCT\OCCT-7_8_0/docQT_DEBUG_PLUGINS=1PATH=%PATH%;D:\Qt\Qt5.14.2\5.14.2\msvc2015_64\bin;D:\Qt\Qt5.14.2\5.14.2\msvc2015_64\plugins\platforms;E:\cpp\code\OCCT\products\freetype-2.5.5-vc14-64\bin;E:\cpp\code\OCCT\products\freeimage-3.17.0-vc14-64\bin;步骤3：复制 D:\Qt\Qt5.14.2\5.14.2\msvc2015_64\plugins 路径下的platforms文件，粘贴到 E:\cpp\code\OCCT\OCCT-7_8_0\build\win64\vc14\bind （生成的build文件里）路径下，如果要在release下运行，则将其粘贴到 E:\cpp\code\OCCT\OCCT-7_8_0\build\win64\vc14\bin路径下。
步骤4：编译运行即可完成。
4、如何自定义测试项目
先看自己修改的结果，在QT窗口自己添加按钮，用于触发函数，然后再在被触发的函数里编写自己的测试代码，就可以完成自定义测试了。
具体来说，需要修改5个地方：
找到OCCT源码里的samples文件（注意，不是build里的samples），进去以后找到OCCTOverview，再找到Code文件夹。我的路径是：E:\cpp\code\OCCT\OCCT-7_8_0\samples\OCCTOverview\code
第一处修改：把自己写的cxx文件和.h文件放在这里（注意：直接在build里右键添加cxx文件是添加不到这里来的，因为那只是在build文件里添加了，而这是OCCT的源码文件，只能在这里添加以后，通过cmake编译进build才行）
具体的cxx和.h文件的写法参考如下，可以仿照源码的 TopologySamples.cxx文件的写法，看我的cxx和TopologySamples.cxx不同的地方即可，按照对应位置改就行。这里我附上我的源码。
#include "PengKaiSamples.h"void PengKaiSamples::ExecuteSample(const TCollection_AsciiString& theSampleName){Standard_Boolean anIsSamplePresent = Standard_True;FindSourceCode(theSampleName);if (theSampleName == "FirstTest")FirstTest();else{myResult << "No function found: " << theSampleName;myCode += TCollection_AsciiString("No function found: ") + theSampleName;anIsSamplePresent = Standard_False;}myIsProcessed = anIsSamplePresent;}void PengKaiSamples::FirstTest(){for (int i = 0; i < 20; i++){std::cout << "enter FirstTest" << std::endl;}}#ifndef PENGKAISAMPLES_H#define PENGKAISAMPLES_H#include "BaseSample.h"#include <AIS_InteractiveContext.hxx>//! Implements PengKai samplesclass PengKaiSamples : public BaseSample{DEFINE_STANDARD_RTTI_INLINE(PengKaiSamples, BaseSample)public:PengKaiSamples(const TCollection_AsciiString& theSampleSourcePath,const Handle(AIS_InteractiveContext)& theContext): BaseSample(theSampleSourcePath, theContext){}protected:virtual void ExecuteSample(const TCollection_AsciiString& theSampleName) Standard_OVERRIDE;private:// One function for every samplevoid FirstTest();};#endif //PENGKAISAMPLES_H第二处修改：添加XML文件
思路：仿照其他xml文件来写
<Menu> <MenuItem name="PengKai"> <MenuItem name="PengKai Test"> <Sample name="FirstTest" function="FirstTest"/> </MenuItem> </MenuItem></Menu>第三处修改：
修改FILES文件，仿照其他人的写法，把cxx文件、xml文件和.h文件添加进去
AdaptorCurve2d_AIS.cxxAdaptorCurve2d_AIS.hAdaptorCurve_AIS.cxxAdaptorCurve_AIS.hAdaptorPnt2d_AIS.cxxAdaptorPnt2d_AIS.hAdaptorVec_AIS.cxxAdaptorVec_AIS.hBaseSample.cxxBaseSample.hDataExchange.xmlDataExchangeSamples.cxxDataExchangeSamples.hGeometry.xmlGeometrySamples.cxxGeometrySamples.hMakeBottle.cxxMakeBottle.hOcaf.xmlOcafSamples.cxxOcafSamples.hSample2D_Face.cxxSample2D_Face.hSample2D_Image.cxxSample2D_Image.hSample2D_Markers.cxxSample2D_Markers.hSamples.qrcTOcafFunction_BoxDriver.cxxTOcafFunction_BoxDriver.hTOcafFunction_CutDriver.cxxTOcafFunction_CutDriver.hTOcafFunction_CylDriver.cxxTOcafFunction_CylDriver.hTOcaf_Application.cxxTOcaf_Application.hTopology.xmlTopologySamples.cxxTopologySamples.hTriangulation.xmlTriangulationSamples.cxxTriangulationSamples.hViewer2d.xmlViewer2dSamples.cxxViewer2dSamples.hViewer3d.xmlViewer3dSamples.cxxViewer3dSamples.hPengKai.xmlPengKaiSamples.cxxPengKaiSamples.h第四处修改：
找到samples文件夹里的qt -> Common -> src，找到这两个cxx文件，进去修改
仿照文件里Topology结构的写法来写，把所有带有Topology的地方全部换成自己修改的名字。
内容太多，这里不易说明，建议直接拿我修改后的代码与源码做对比，可以看出添加的部分在哪里

5、总结
注意好以下几个关键点：
1、环境和软件以及源码提前准备好
2、Cmake编译的时候记得修改成自己文件路径所在位置
3、一般而言配置完以后运行成功就行，自定义测试需要修改的地方较多，不易操作
