Error when including .h from another package in the same workspace?

edit

Hello

I have created a package GA_palnner for a custom global planner based on Genetic Algorithm.

Under src of GA_palnner:

CrossPoint.cpp , GA_global_planner_ros.cpp , GenericPathPlanner.cpp , Map.cpp , OccupancyGridMap.cpp , Path.cpp , Population.cpp

Under include of GA_palnner:

CrossPoint.h , GA_global_planner_ros.h , GenericPathPlanner.h , Map.h , OccupancyGridMap.h , Path.h , Population.h

The GA_planner works successfully as global planner plugin and I am able to move my robot in Gazeo using this planner.

Now, I created a package ros_global_planners_experiment to compare the performance of navfn and GA_planner ( gives the path length and running time for each).

In ros_global_planners_experiment_node.cpp

#include <ros/ros.h>
#include <costmap_2d/costmap_2d_ros.h>

#include <navfn/navfn_ros.h> // packageName/headerFile.h
#include "GA_planner/GA_global_planner_ros.h"

Gives me error:

fatal error: GA_global_planner_ros.h: No such file or directory #include "GA_global_planner_ros.h"

This is the package .xml and cMakeLists.txt for both GA_planner and ros_global_planners_experiment
