Solution :  Add these header files

Search for kdtree_flann.h  and kdtree_flann.hpp and add those as header files

#include < / home/sai/fuerte_workspace/perception_pcl/pcl/build/pcl_trunk/kdtree/include/pcl/kdtree/kdtree_flann.h>
#include < / home/sai/fuerte_workspace/perception_pcl/pcl/build/pcl_trunk/kdtree/include/pcl/kdtree/impl/kdtree_flann.hpp>
