CMake error trying to link target to libraries
Dear All, I am using Ubuntu 14.04 and ROS Indigo.
I have created a pkg named "joy" in which there are two source file named joystick.cpp and js_info.cpp under joy/src folder. also i have header file joystick.h under include/joy folder.
i have compiled that 3 files and they work correctly.
But when i placed this files as told you above, gives me error as shown below:
CMake Error at joy/CMakeLists.txt:61 (target_link_libraries):
Target "joystick" of type EXECUTABLE may not be linked into another target.
One may link only to STATIC or SHARED libraries, or to executables with the
ENABLE_EXPORTS property set.
-- Configuring incomplete, errors occurred!

See also "/home/darshan/catkin_ws/build/CMakeFiles/CMakeError.log".
make: *** [cmake_check_build_system] Error 1
Invoking "make cmake_check_build_system" failed
This below shown is my CMakeLists.txt file:
cmake_minimum_required(VERSION 2.8.3)
project(joy)
find_package(catkin REQUIRED COMPONENTS
roscpp
rospy
std_msgs
)
catkin_package(
INCLUDE_DIRS include
CATKIN_DEPENDS roscpp rospy std_msgs
)
include_directories(include
${catkin_INCLUDE_DIRS}
)
add_executable(joystick src/joystick.cpp)
target_link_libraries(joystick ${catkin_LIBRARIES})
add_executable(js_info src/js_info.cpp)
target_link_libraries(js_info ${catkin_LIBRARIES} joystick)
Please provide me the solution. I would be thankful to all of you.
Edit: Thank you so much for quick and prompt reply.
But if i change that line to
target_link_libraries(js_info ${catkin_LIBRARIES} )
like this. I get the following error.

May I suggest to change the title of your question? It has nothing to do with header files. Perhaps something like "CMake error trying to link target to libraries" is more appropriate.
Also, a ROS package with the name joy already exists. This will cause problems if you need both packages at the same time.
