Hey, does anyone could tell me how to configure the qtcreator IDE to have references for ROS2 libraries? (references for headers). I open the ros workspace and then I go Tools - > Options - > Kits -> Cmake Tool -> I change for colcon , but when I click build I have:

:-1: error: No rule to make target 'all'.  Stop.
error: use of undeclared identifier 'rclcpp'
