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

edit

I have created a package using catkin_create_pkg on my raspberry pi 3 where I have previously installed Ubuntu Xenial and ROS kinetic. I'm trying to use a Pixy Camera in ROS with this code pixy_ros ,but everytime I am trying to compile (doing catkin_make) the cpp with file included in the created package I get the following error:

[ 78%] Building CXX object pixy_node/CMakeFiles/pixy_node.dir/src/pixy_node.cpp.o

In my CMakeLists.txt file, I have the following:

cmake_minimum_required(VERSION 2.8.3)
project(pixy_node)

## Find catkin macros and libraries
## if COMPONENTS list like find_package(catkin REQUIRED COMPONENTS xyz)
## is used, also find other catkin packages

find_package(catkin REQUIRED COMPONENTS sensor_msgs message_generation roscpp tf rospy)

## System dependencies are found with CMake's conventions
find_package(Boost REQUIRED COMPONENTS thread system chrono)


## Uncomment this if the package has a setup.py. This macro ensures
## modules and global scripts declared therein get installed
## See http://ros.org/doc/api/catkin/html/user_guide/setup_dot_py.html
# catkin_python_setup()

add_subdirectory(libpixyusb)
set (CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${libpixyusb_SOURCE_DIR}/cmake" )
find_package ( libusb-1.0 REQUIRED )
