ROS noetic, fatal error: ros/ros.h: No such file or directory

edit

Hi everyone, I'm trying to start a c++ script (simply the listener from the ROS tutorial, just with the name subpub.cpp) but I get the error "fatal error: ros/ros.h: No such file or directory".

I tried looking at the old questions about this, but they don't seem to work for me.

I am using noetic on ubunto, and the catkin_make does not give any errors.

this is my package.xml file:

<?xml version="1.0"?>
<package format="2">
  <name>infoexc</name>
  <version>0.0.0</version>
  <description>The infoexc package</description>
  <maintainer email="cnr@todo.todo">cnr</maintainer>
  <license>TODO</license>
  <buildtool_depend>catkin</buildtool_depend>
  <build_depend>roscpp</build_depend>
  <build_depend>rospy</build_depend>
  <build_depend>std_msgs</build_depend>
  <build_export_depend>roscpp</build_export_depend>
  <build_export_depend>rospy</build_export_depend>
  <build_export_depend>std_msgs</build_export_depend>
  <exec_depend>roscpp</exec_depend>
  <exec_depend>rospy</exec_depend>
  <exec_depend>std_msgs</exec_depend>
  <export>
    <!-- Other tools can request additional information be placed here -->
  </export>
</package>

and this is my CMakeLists.txt file:

cmake_minimum_required(VERSION 3.0.2)
project(infoexc)

find_package(catkin REQUIRED COMPONENTS
  roscpp
  rospy
  std_msgs
)
include_directories(
  ${catkin_INCLUDE_DIRS}
)
add_executable(subpub scripts/C++/subpub.cpp)
target_link_libraries(subpub ${catkin_LIBRARIES})

Scripts in c++ are in /catkin_ws/src/infoexc/scripts/C++, everything worked fine in python.

Thanks in advance!
