replacing your rosbuild_add_executable line with this should make it work:

rosbuild_add_executable(homography_generator
src/homography_generator.cpp src/CeilingNode.cpp)

the rosbuild_add_executable macro is a wrapper around CMake's
add_executable macro. Documentation here:
http://www.ros.org/wiki/rosbuild/CMakeLists
