std_srvs not found in ros2

edit

I want to include a service from std_srvs like I do in the beginning in my C++ Code:

#include "std_srvs/srv/SetBool.hpp"

in my CMakeLists.txt I included the following lines:

cmake_minimum_required(VERSION 3.8)
project(test_node)

if(CMAKE_COMPILER_IS_GNUCXX OR CMAKE_CXX_COMPILER_ID MATCHES "Clang")
add_compile_options(-Wall -Wextra -Wpedantic)
endif()

# find dependencies
find_package(ament_cmake REQUIRED)
find_package(rclcpp REQUIRED)
find_package(std_srvs REQUIRED)

if(BUILD_TESTING)
  find_package(ament_lint_auto REQUIRED)
  # the following line skips the linter which checks for copyrights
  # uncomment the line when a copyright and license is not present in all source files
  #set(ament_cmake_copyright_FOUND TRUE)
  # the following line skips cpplint (only works in a git repo)
  # uncomment the line when this package is not in a git repo
  #set(ament_cmake_cpplint_FOUND TRUE)
  ament_lint_auto_find_test_dependencies()
endif()

add_executable(testing src/testing.cpp)
ament_target_dependencies(testing
    rclcpp
    std_srvs
)

install(TARGETS testing 
    EXPORT export_${PROJECT_NAME}
    DESTINATION lib/${PROJECT_NAME}
 )

ament_package()

but when I run colcon build I alwas get the error:

fatal error: example_interfaces/srv/SetBool.hpp: No such file or directory
4 | #include "std_srvs/srv/SetBool.hpp"

What I am doing wrong here? How can I include this service for my node ?
