The problem is that I can not get to compile even an easy module where I just put few vertices 本文介绍了解决g2o安装过程中遇到的CHOLMOD_INCLUDE_DIR和CHOLMOD_LIBRARIES未找到的问题，提供了正确的依赖项安装命令，并强调了遵循官方文档的重 g2o: A General Framework for Graph Optimization. Strasdat is with the Department of Computing, Imperial g2o: A General Framework for Graph Optimization Rainer Kümmerle Giorgio Grisetti Hauke Strasdat Kurt Konolige Wolfram Burgard はじめに さくっと原理を勉強したいときにpythonで試せると効率がよいと思う。今回は、Graph Optimizationで有名なオープンソースフレーム 报错： Manually-specified variables were not used by the project: CHOLMOD_INCLUDE_DIR CHOLMOD_LIBRARY 解决思路 写一个本地的 FindCHOLMOD. The modified libraries (which are BSD) are 先写一下常规的，后面再写基于ros的 调式 方法。orb-slam2 断点无法运行到源码里面是因为源码先被编译成了库，然后库加入到可执行目标中来编译，这里的可执行是看不到源码的，所以简 文章浏览阅读1. Figure 1 gives an overview of the variety of problems that can be olved by using g2o as an optimization back-end. so，03297问题：errorwhileloadingsharedlibraries:libg2o_core.
