Error compiling c++ code (ros/ros.h: No such file or directory)

edit

Hello. Im using ubuntu 20.4 , ros noetic and gazebo 11 trying to move a robot using cubic polynomials and c++. At the beginning of the file I have these inlcudes:

#include <ros/ros.h>
#include <tf/tf.h>
#include <geometry_msgs/Twist.h>
#include <geometry_msgs/Pose.h>
#include <nav_msgs/Odometry.h>
#include <math.h>

When I compile the file ,I get this error:

traj_gen_cubic.cpp:1:10: fatal error: ros/ros.h: No such file or directory
    1 | #include <ros/ros.h>
      |          ^~~~~~~~~~~
compilation terminated.

This is my CMakeLists.txt file:

cmake_minimum_required(VERSION 2.8.3)
project(husky_ur3_gazebo)

find_package(catkin REQUIRED COMPONENTS
  roscpp
  std_msgs
  roslaunch
)

catkin_package(
  CATKIN_DEPENDS roscpp std_msgs
)
include_directories(${catkin_INCLUDE_DIRS})


add_executable(gazebo_rh_pub src/gazebo_rh_pub.cpp)
add_dependencies(gazebo_rh_pub ${${PROJECT_NAME}_EXPORTED_TARGETS} ${catkin_EXPORTED_TARGETS})
target_link_libraries(gazebo_rh_pub ${catkin_LIBRARIES})

install(TARGETS gazebo_rh_pub
  RUNTIME DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}
)


install(DIRECTORY launch controller DESTINATION ${CATKIN_PACKAGE_SHARE_DESTINATION})

What should I do?
