Hector Nav Msgs build error - in Eclipse

edit

I am new to ROS, and Linux, but have experience with Eclipse in windows environment. I have a few nodes (including Hector SLAM catkin) all functioning using ROS_MAKE and ROSRUN from the terminal. I know the code is OK. Now working to setup eclipse, and am to the point where the nodes will compile in Eclipse so I have worked out the obvious dependencies issue that plague many people including myself. (using this page: wiki.ros.org/ODEs#Eclipse)

Error now is that in some of the build files the get_pkg_map is being called but not getting returned and instead generates error that CMAKE_PREFIX_PATH environment variable isn't set. Exact error wording is below.

I have added the CMAKE_PREFIX_PATH environment variable to Eclipse and set it to same value as echo'd by terminal. "/home/linux/catkin_ws/devel:/opt/ros/jade"

Can you point me towards what I am missing? I apologize if this belongs in an Eclipse forum but the files generating the errors are part of ROS so thought better to start here. Appreciate any help you can provide.
