pcl_visualization-eigen-package

edit

I have found pcl_visualization in the following:

• svn: uri: https://code.ros.org/svn/ros-pkg/stacks/perception_pcl_addons/tags/unstable

When I am trying to run rosmake perception_pcl_addons i get the follwoing error:

'pcl_visualization' depends on non-existent package 'eigen'

I have eigen-config.cmake eigen-config-version.cmake in:

/opt/ros/groovy/share/eigen/cmake$

Can I generate the eigen package from this eigen-config.cmake?

Or where can I find that package?

I am have groovy installed in my system

Cheers
