I am new to ROS (Indigo), and I want to write a C++ program to use the MoveIt! package.

However, I am confused as to what I need to have in my CMakeLists.txt file, such that the header and library files can be found.

For example, here is the file so far:

cmake_minimum_required(VERSION 2.8.1)

project(MicoMoveIt)

set(CMAKE_CXX_FLAGS "-std=c++11")

file(GLOB srcs *.cpp)

include_directories(/opt/ros/indigo/include)

link_directories(/opt/ros/indigo/lib)

add_executable(${PROJECT_NAME} ${srcs})

And my main.cpp file is:

#include <ros/ros.h>
#include <moveit/move_group_interface/move_group.h>

int main()
{
    moveit::planning_interface::MoveGroup group("right_arm");
    return 0;
}

But compiling this gives me the error:

/opt/ros/indigo/include/moveit/robot_model/joint_model.h:47: error: Eigen/Geometry: No such file or directory
 #include <Eigen/Geometry>
                          ^

So, I need to specify where to find these Eigen header files. But given that Eigen is a dependency of MoveIt!, then I shouldn't have to manually include all these header file directories.

How should I be writing the CMakeLists.txt file so that all header and library directories of dependencies are included?

Did you review the extensive documentation on CMakeLists.txt and catkin and the catkin docs?

For what it's worth,

Could you try to install these packages:

ros-indigo-eigen-utils, ros-indigo-eigen-conversions

I'm using currently groovy and I don't have any experiences with indigo, but did you follow this tutorial ?

I would suggest you to follow all the tutorials for the beginner before writing any code.

The question is not really related to the problem, but here's my answer to your actual problem with Eigen specifically. It's an issue with Ubuntu 14.04's installation of Eigen3 which I guess must have changed since the Moveit code was written. You can fix this by creating a symlink from /usr/include/eigen3/Eigen to /usr/local/include/Eigen and CMake should be able to find the libraries. Of course, double-check that those libraries really do exist in that path.
