node not built, but executable is built?

edit

Hi, I'm trying to "pull" PTAM out of the TUM ARDrone package, so that I can build a package just using the stateestimation node, and nothing else. The first step of this was to create a package called ptam which is a copy of TUM ARDrone but I commented out the instructions in the CMakeList.txt which build the other nodes. With a few more changes it built succesfully, and told me

Linking CXX executable /home/highbay-linux/ptam_ws/devel/lib/ptam/drone_stateestimation
[100%] Built target drone_stateestimation

Yet when I try to run rosrun ptam and hit TAB, nothing comes up, in fact when I run rosrun pTAB, it doesnt pull up ptam as an option. I sourced my workspace corectly, so I don't know why, if the target exacutable was built, I dont have any nodes to run?

Here is the amended CMakeList.txt

cmake_minimum_required(VERSION 2.8.3)
project(ptam)
