CloudCompare编译

1、下载CloudCompare源代码，解压（本人是放于 F:\1_CloudCompare）；

2、下载CCCoreLib源代码，解压路径：F:\1_CloudCompare\libs\qCC_db\extern\CCCoreLib；

3、下载nanoflann源代码，解压路径：F:\1_CloudCompare\libs\qCC_db\extern\CCCoreLib\extern\nanoflann

4、打开CMake，添加路径：

5、添加变量

（1）CMAKE_PREFIX_PATH，指向QT安装路径，如D:/Qt/5.15.2/msvc2019_64

（2）CMAKE_INSTALL_PREFIX，指定安装目录，如../Install

6、Configure & Generate

7、打开项目，编译

8、编译错误 C2653 “QCoreApplication”: 不是类或命名空间名称 CCCoreLib F:\1_CloudCompare\libs\qCC_db\extern\CCCoreLib\src\DgmOctree.cpp 3428

解决：

DgmOctree.h添加#include <QCoreApplication>

9、编译错误：E0135 namespace "nanoflann" 没有成员 "SearchParams" CCCoreLib F:\1_CloudCompare\libs\qCC_db\extern\CCCoreLib\src\Kriging.cpp 358

可能是代码版本不匹配，先不去管，做注释处理

10、编译错误：

详细错误日志为：

找到对应的CMake文件，将该行注释掉
