Cmake报错-Could not find a package configuration file provided by...

catkin_make报错：

CMake Error at /opt/ros/melodic/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
  Could not find a package configuration file provided by "serial" with any
  of the following names:
 
    serialConfig.cmake
    serial-config.cmake
 
  Add the installation prefix of "serial" to CMAKE_PREFIX_PATH or set
  "serial_DIR" to a directory containing one of the above files.  If "serial"
  provides a separate development package or SDK, be sure it has been
  installed.
Call Stack (most recent call first):
  pnc/CMakeLists.txt:37 (find_package)

解决方法：

方法一：

sudo apt-get install ros-melodic-serial

其中melodic为ubuntu18.04对应的ROS版本，可根据自己的版本修改。

问题解决。

方法二：

也可以一次性安装所有的包：

sudo apt-get install ros-melodic-*

不太建议第二种方法，需要15个G的空间，可以根据需要哪个包安装哪个包即可。
