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

Hello, I get the following error when trying to compile pixy_node

[ 37%] Building CXX object pixy_ros/CMakeFiles/pixy_node.dir/src/pixy_node.cpp.o
/home/pi/catkin_ws/src/pixy_ros/src/pixy_node.cpp:21:21: fatal error: ros/ros.h: No such file or directory

I modified the CMakeLists.txt, adding the entry ${catkin_INCLUDE_DIRS} to the include_directories directive, from

include_directories(include libpixyusb/include libpixyusb/common ${LIBUSB_1_INCLUDE_DIRS} )

to the following and worked

include_directories(include libpixyusb/include libpixyusb/common ${LIBUSB_1_INCLUDE_DIRS} ${catkin_INCLUDE_DIRS})

thanks,
