ros/ros.h header file not found

edit

Hello, I'm pretty new to ROS and I'm implementing a Service node in C++, the problem is, when I try to include the "ros/ros.h" header file, it is not found, and the header file of my service file isn't found either, although it is correctly contained in catkin_ws/devel/include/my_package, I've found that this problem is often caused by an error of configuration in the CMakeLists.txt, but I tried the solutions that were posted in the thread I consulted and it didn't help. My ROS version is Kinetic Kame and I'm using Ubuntu 16.04.

Here's my CMakeLists.txt:

cmake_minimum_required(VERSION 2.8.3)
project(beginner_tutorials)

add_message_files(
   FILES
   Num.msg
   Sensor.msg
  )

add_service_files(
  FILES
  AddTwoInts.srv
  CaracteresComunes.srv
 )


generate_messages(
  DEPENDENCIES
  std_msgs
 )


catkin_package(
   INCLUDE_DIRS include
   LIBRARIES beginner_tutorials
   CATKIN_DEPENDS roscpp rospy std_msgs message_runtime
   DEPENDS system_lib
)




include_directories(${catkin_INCLUDE_DIRS})

add_executable(talker src/talker.cpp)
target_link_libraries(talker ${catkin_LIBRARIES})
add_dependencies(talker beginner_tutorials_generate_messages_cpp)

add_executable(listener src/listener.cpp)
target_link_libraries(listener ${catkin_LIBRARIES})
add_dependencies(listener beginner_tutorials_generate_messages_cpp)


add_executable(SumarServer src/add_two_ints_server.cpp)
target_link_libraries(SumarServer ${catkin_LIBRARIES})
add_dependencies(SumarServer beginner_tutorials_gencpp)

add_executable(SumarClient src/add_two_ints_client.cpp)
target_link_libraries(SumarClient ${catkin_LIBRARIES})
add_dependencies(SumarClient beginner_tutorials_gencpp)

add_executable(CCServer src/CCServer.cpp)
target_link_libraries(CCServer ${catkin_LIBRARIES})
add_dependencies(CCServer beginner_tutorials_gencpp)

And my package.xml just in case:

<?xml version="1.0"?>
<package format="2">

I would really appreciate the help, guys
