I have an error when doing cmake [actually rosmake] to my project, I have already installed OpenCV but I have this error:

How to solve it?

Did you go through the beginner tutorials? That should tell you how to properly make a ROS package.

From your error messages:

1. Don't call cmake directly. Use make or rosmake.

2. Are you using cturtle? I think you system setup might be inconsistent.

Note: I have already installed all the requested packages by (an example):

sudo apt-get install ros-cturtle-image-common

the same error is shown when I trying to install dependencies by

rosdep install mypackage

I think these installed packages must add to ROS_PACKAGE_PATH but I don't know their paths!

Thanks for your reply, Actually I have read the tutorial about making ROS package at : http://www.ros.org/wiki/ROS/Tutorials/BuildingPackages

when I have put something like:

$ roscd mypackage
$ cat manifest.xml

Then it's ok, and it gives me list of dependent packages,

<package>
  <description brief="mypackage">

     mypackage

  </description>
    ...
      <depend package="roscpp"/>
      <depend package="sensor_msgs"/>
      <depend package="cv_bridge"/>
      <depend package="image_transport"/>
      <depend package="std_msgs"/>
      <depend package="mypackage2"/>

    </package>

but when I put

rosdep install mypackage

it gives me an error:

I have solved previous problem using rosmake, but now I have these errors..

I'm new to ros and trying to do:

 cmake CMakeLists.txt

this file includes some ros libraries but I have an error:

[rosbuild] Building package mypackage
