Not sure how to add opencv library to CMakeLists.txt

I'm using Apple, CMake 2.8.1 in order to build my project on Ubuntu 10.04:

cmake_minimum_required(VERSION 2.4.6)
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} /home/user/workspace)
include($ENV{ROS_ROOT}/core/rosbuild/rosbuild.cmake)

# Set the build type.  Options are:
#  Coverage       : w/ debug symbols, w/o optimization, w/ code-coverage
#  Debug          : w/ debug symbols, w/o optimization
#  Release        : w/o debug symbols, w/ optimization
#  RelWithDebInfo : w/ debug symbols, w/ optimization
#  MinSizeRel     : w/o debug symbols, w/ optimization, stripped binaries
#set(ROS_BUILD_TYPE RelWithDebInfo)

rosbuild_init()
find_package(OpenCV 2) 

#set the default path for built executables to the "bin" directory
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
#set the default path for built libraries to the "lib" directory
set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)

#uncomment if you have defined messages
#rosbuild_genmsg()
#uncomment if you have defined services
#rosbuild_gensrv()

#common commands for building c++ executables and libraries
#rosbuild_add_library(${PROJECT_NAME} src/example.cpp)
#target_link_libraries(${PROJECT_NAME} another_library)
#rosbuild_add_boost_directories()
#rosbuild_link_boost(${PROJECT_NAME} thread)
#rosbuild_add_executable(example examples/example.cpp)
#target_link_libraries(example ${PROJECT_NAME})

include_directories(${CMAKE_SOURCE_DIR}/include${OpenCV_INCLUDE_DIRS})

rosbuild_add_executable (RosPub src/paste.cpp)
target_link_libraries (RosPub openni_driver usb-1.0 ${OpenCV_LIBS})

I need to add OpenCV libraries on my project. I have added them but I can't still get my code to work. It keeps outputting this error:

struct MyOpenNIExample::ImgContext’ has no member named ‘image’

There are a few of them:

After I added find_package(OpenCV REQUIRED) to the CMakeLists.txt, I got this error:

Adjust CMAKE_MODULE_PATH to find FindOpenCV.cmake or set OpenCV_DIR  
 to the directory containing a CMake configuration file for OpenCV.  
 The file will have one of the following names:
         OpenCVConfig.cmake
         opencv-config.cmake

Since I need:

#include "opencv2/opencv.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc.hpp"

I added

find_package(OpenCV 2), 
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} /home/user/workspace)

and

include_directories(${CMAKE_SOURCE_DIR}/include${OpenCV_INCLUDE_DIRS})
target_link_libraries (RosPub openni_driver usb-1.0 ${OpenCV_LIBS})

What should I do?

Solution

#include "opencv2\opencv.hpp"
#include "opencv2\highgui\highgui.hpp" 
#include "opencv2\imgproc\imgproc.hpp"

the include files above are included in the vision_opencv in ROS. so to include it, add the opencv dependency in the manifest file.

That would help.
