VS code can't find the headerfiles even when workspace compiles without error

edit

Okay, I'll have a look, Thanks!

you may look at https://marketplace.visualstudio.com/... looks interresting

I have that extension already, still doesn't get the header files. Btw, do you know if adding these lines to my CMakelist would be helpful or not?

catkin_package(
  INCLUDE_DIRS include
  LIBRARIES generate_waypoint
  CATKIN_DEPENDS geometry_msgs roscpp rospy std_msgs tf visualization_msgs
  DEPENDS system_lib
)

I usually just have all of them commented out, resulting in catkin_package()

And also this:

include_directories(
  include
  ${catkin_INCLUDE_DIRS}
)

By default the include is commented out though, resulting in:

include_directories(
  # include
  ${catkin_INCLUDE_DIRS}
)
