Could not find CMake package configuration file for “Eigen3”

Question

When I enter this command:

cd /Users/mona/ros_catkin_ws/build_isolated/pcl_ros && /Users/mona/ros_catkin_ws/install_isolated/env.sh cmake /Users/mona         


        

Answer 1

You have to install Eigen3. It provides the FindEigen3.cmake file. The error occurs because the project you want to configure, has a dependency to Eigen3.

If you have Eigen3 installed, follow the error message and add Eigen3 to CMake's search path.
