如何将Ceres链接到CGAL以使用平滑功能? [英] How to link Ceres to CGAL to use Smoothing functions?

问题描述

我已经构建了Ceres软件包及其依赖项，现在我正尝试使用CGAL库执行平滑操作，但是却遇到一个错误:基于区域的平滑处理需要ceres库".

I've built the Ceres package and its dependencies, now I'm trying to use the CGAL library to perform smoothing but I'm getting an error: "area-based smoothing requires ceres library".

我如何合并Ceres库?CGAL平滑示例未提及这一点，并且没有Ceres库中的任何包含项.

How am I to incorporate the Ceres library? The CGAL smoothing example doesn't mention this and does not have any includes from the Ceres library.

我在仅进行标头模式下使用CGAL而不进行编译，是否需要先编译CGAL?

I'm using CGAL in header-only mode without compilation, is it necessary to compile CGAL first?

推荐答案

在使用平滑的示例的cmake脚本中，您可以看到以下行:

In the cmake script of the examples using the smoothing, you can see the following line:

target_compile_definitions( mesh_smoothing_example PRIVATE CGAL_PMP_USE_CERES_SOLVER )

等价于在代码中添加 #define CGAL_PMP_USE_CERES_SOLVER .

合理的原因是，如果cmake未找到该库，则该代码将被禁用.

The rational is that if the lib is not found by cmake, the code will be disabled.

我同意没有正确记录该文件.已经发布了一个问题/PR，以改善这种情况.

I agree that it is not correctly documented. An issue/PR has already been opened to improve the situation.
