I'd like anyone to teach me what planner in global planner means.

CMakeLists.txt in globalplanner has planner as addexecutable and and targetlinklibraries.

addexecutable(planner
  src/plannode.cpp
)
targetlinklibraries(planner
  ${PROJECTNAME}
  ${catkinLIBRARIES}
)

PROJECTNAME means project(globalplanner).
CMakeLists.txt in Carrotplanner has carrotplanner as targetlinklibraries.

addlibrary(carrotplanner src/carrotplanner.cpp)
targetlinklibraries(carrotplanner
    ${catkinLIBRARIES}
    )

Does it mean that I can use rosrun globalplanner planner as globalplanner has a plannode.cpp.
and

int main(int argc, char** argv) {
    ros::init(argc, argv, "global_planner");


tf::TransformListener tf(ros::Duration(10));
costmap_2d::Costmap2DROS lcr("costmap", tf);
global_planner::PlannerWithCostmap pppp(<b>"planner"</b>, &lcr);
ros::spin();
return 0;


}

Does this"planner" correspond with addexecutable(planner src/plannode.cpp ) ? Could anyone tell me about it? Thank you in advance!

following globalplanner, I edited my code, compiling it. As the result, I got library and executable.
