Could not find a package configuration file provided by “catkin“ : catkinConfig.cmake 解決方法

一、問題描述

自己編譯 Autoware 的時候遇到如下問題：

CMake Error at CMakeLists.txt:4 (find_package):
  By not providing "Findcatkin.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "catkin", but
  CMake did not find one.

  Could not find a package configuration file provided by "catkin" with any
  of the following names:

    catkinConfig.cmake
    catkin-config.cmake

  Add the installation prefix of "catkin" to CMAKE_PREFIX_PATH or set
  "catkin_DIR" to a directory containing one of the above files.  If "catkin"
  provides a separate development package or SDK, be sure it has been
  installed.

           

二、參考解決方法

（這裡隻給出參考解決方法，主要原因是自己不是很确定就是通過這種方法來解決的這個問題。）

系統缺少 catkin 這個包，直接安裝就可以。

sudo apt-get install ros-melodic-catkin
           

注意，還是沒有作用，不建議執行

sudo apt-get remove ros-melodic-catkin

,因為這條指令會把你電腦的 ROS 解除安裝掉。别問我是怎麼知道的…
