Package.xml on creating srv (Unit 1)

Course Support Mastering with ROS - SUMMITXL

Hello, just wanted to make sure.
Whenever you insert a package into find_package function from the CMake, you need to insert it as a build_depend in the package.xml right??

So, if we needed to insert in the CMake:

find_package(catkin REQUIRED COMPONENTS
  rospy
  std_msgs
  message_generation
)

The package.xml should look like this:

  <buildtool_depend>catkin</buildtool_depend>
  <build_depend>message_generation</build_depend>
  <build_depend>std_msgs</build_depend>
  <build_depend>rospy</build_depend>
  <build_export_depend>message_runtime</build_export_depend>
  <exec_depend>rospy</exec_depend>

`I wanted to post this, since in the “solution” it says we just need to load std_msgs with build_depend.

Thanks from advance.
Bests,
Ángel López

One way to kill this for sure is to pass your dependencies to the catkin_create_pkg command:

catkin_create_pkg whatever_package rospy std_msgs message_generation

Anyway, if something critical is missing the compilation will fail.
