autoware配置等相关的问题

问题遇到的现象和发生背景

autoware1.14编译时出现许多报错，到了不会解决的地方了。

操作环境、软件版本等信息

ubuntu18.04 。autoware.ai-1.14

尝试过的解决方法

前面的报错都解决了 ，到了看不懂的地方了没有什么头绪。
目前是想到了用ros装一下少的包，但是感觉不是这个问题。想来看看大家的建议

我想要达到的结果

完成编译。正常运行软件

报错如下，CMakeList的find_package()是这一块有问题吗，不了解这个。

CMake Error at /opt/ros/melodic/share/pcl_conversions/cmake/pcl_conversionsConfig.cmake:113 (message):
  Project 'pcl_conversions' specifies '/usr/include/eigen3' as an include
  dir, which is not found.  It does neither exist as an absolute directory
  nor in '${prefix}//usr/include/eigen3'.  Check the issue tracker
  'https://github.com/ros-perception/perception_pcl/issues' and consider
  creating a ticket if the problem has not been reported yet.
Call Stack (most recent call first):

  CMakeLists.txt:4 (find_package)

你的库安装目录识别不到，用命令指定下其他目录或者检查库是否安装

export EIGEN3_INCLUDE_DIR=/usr/include/eigen3
/重装
sudo apt-get install libeigen3-dev
