new executable not showing up in bin after rosmake [closed]

edit

I'm trying to modify openni_tracker.cpp in the openni_tracker package. If I create a copy or even modify the current one and run rosmake it never puts a new executable in the bin folder. The line commented out when it was in there had no effect. I'm sure I'm missing something basic but I can't figure it out from the tutorials.

Here's my CMakeLists.txt file.

cmake_minimum_required(VERSION 2.4.6)
include($ENV{ROS_ROOT}/core/rosbuild/rosbuild.cmake)
rosbuild_init()
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
rosbuild_add_executable(openni_tracker src/openni_tracker.cpp)
#rosbuild_add_executable(openni_tracker_2 src/openni_tracker_2.cpp openni_tracker src/openni_tracker.cpp)
