5、总结
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_0 CSF_FPE=0 CSF_OCCTResourcePath=E:\cpp\code\OCCT\OCCT-7_8_0/src CSF_OCCTDataPath=E:\cpp\code\OCCT\OCCT-7_8_0/data CSF_OCCTSamplesPath=E:\cpp\code\OCCT\OCCT-7_8_0/samples CSF_OCCTTestsPath=E:\cpp\code\OCCT\OCCT-7_8_0/tests CSF_OCCTDocPath=E:\cpp\code\OCCT\OCCT-7_8_0/doc QT_DEBUG_PLUGINS=1 PATH=%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。
