By not providing "pcl_catkin" in

问题描述

运行catkin build point_cloud_registration时，报错：
By not providing "pcl_catkin" in CMAKE_MODULE_PATH this project

解决方案

cd ~/catkin_ws_robust_pcl/src
gedit CMakeLists.txt
set(pcl_catkin PATH) #前面是pcl_catkin，后面是pcl_catkin中.cmak的路径

后面再运行catkin build point_cloud_registration，pcl_catkin的安装过程大概50min左右，因为电脑配置不咋地，中间卡死N次，耐心等待吧。
