ubuntu20.04编译文件时找不到pcl

问题：

CMake Error at /lib/x86_64-linux-gnu/cmake/pcl/PCLConfig.cmake:62 (message):
  PCL can not be found on this machine
Call Stack (most recent call first):
  /lib/x86_64-linux-gnu/cmake/pcl/PCLConfig.cmake:452 (pcl_report_not_found)
  CMakeLists.txt:11 (find_package)

解决方法：新建路径，并将pcl链接过去

sudo mkdir /lib/x86_64-linux-gnu/cmake/pcl/include
sudo ln -s /usr/include/pcl-1.10/pcl /lib/x86_64-linux-gnu/cmake/pcl/include/pcl
