Could not find a package configuration file provided by "opencv2"

edit

I was following the Converting between ROS images and OpenCV images (Python) tutorial and i came across the following problem while running catkin_make. I am new to ros and i am still finding my way around it. I have installed opencv and have tried out the solutions suggested in other threads, but none of them seem to work. This is the error i get while executing catkin_make.

  CMake Error at /opt/ros/indigo/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
  Could not find a package configuration file provided by "opencv2" with any
  of the following names:

    opencv2Config.cmake
    opencv2-config.cmake

  Add the installation prefix of "opencv2" to CMAKE_PREFIX_PATH or set
  "opencv2_DIR" to a directory containing one of the above files.  If
  "opencv2" provides a separate development package or SDK, be sure it has
  been installed.

my CMakeLists file has the following content

cmake_minimum_required(VERSION 2.8.3)
project(opencv_test)
find_package(catkin REQUIRED COMPONENTS
  cv_bridge
  opencv2
  rospy
  sensor_msgs
  std_msgs
)
find_package(OpenCV)
include_directories(
  ${catkin_INCLUDE_DIRS}
)
include_directories(${OpenCV_INCLUDE_DIRS})
target_link_libraries(opencv_test ${OpenCV_LIBRARIES})
