Dependency conflict while making TUM example

[kmfrick]

The DS_SLAM_BUILD.sh file errors out while building the TUM example

CMake Warning at /opt/ros/kinetic/share/ros/core/rosbuild/public.cmake:509 (add_executable):

It compiles anyway, but won't this cause problems down the line?

If it can compile successfully, you can omit that. Maybe I should rewrite the CMakeLists, or welcome to pull requests~~
