rosrun: unable to locate the node robot_state_publisher

edit

The exact error I am having is

ERROR: cannot launch node of type [robot_state_publisher/state_publisher]: can't locate node [state_publisher] in package [robot_state_publisher]

I have cloned the robot_state_publisher from ros wiki and already had done rosmake.

I have also sourced the terminal to devel before using rosrun aswell as exported all the reqaquired core packages and python path to the terminal before trying to run the robot_state_publisher.

here is the my CmakeList.txt file,

cmake_minimum_required(VERSION 2.8)
project(robot_state_publisher)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -Wall -Wextra")

find_package(orocos_kdl REQUIRED)
find_package(catkin REQUIRED
  COMPONENTS roscpp rosconsole rostime tf tf2_ros tf2_kdl kdl_parser
)
find_package(Eigen3 REQUIRED)

find_package(urdfdom_headers REQUIRED)

catkin_package(

add_library(joint_state_listener src/joint_state_listener.cpp)
target_link_libraries(joint_state_listener ${PROJECT_NAME}_solver ${orocos_kdl_LIBRARIES})

add_executable(${PROJECT_NAME} src/joint_state_listener.cpp)
target_link_libraries(${PROJECT_NAME} ${PROJECT_NAME}_solver ${orocos_kdl_LIBRARIES})

# compile the same executable using the old name as well
add_executable(state_publisher src/joint_state_listener.cpp)
target_link_libraries(state_publisher ${PROJECT_NAME}_solver ${orocos_kdl_LIBRARIES})

Can you please help me solve this problem, I am trying to run a robot I have designed using xacro on gazebo and control it with ros. I have already installed ros_control and ros_gazebo packages. Thank you advance,
