Looking at the CMakeLists.txt for
pr2_2dnav for Hydro, it would appear that the launch file is not installed (the build script is missing an
install(..) rule). That would result in the error message you quoted.
You can check this by doing a
ls -al /opt/ros/hydro/share/pr2_2dnav/ and then look for the
pr2_2dnav.launch file in the listing. It will most likely not be there.
If the file is missing, please log an issue on the
pr2_navigation_apps issue tracker.

under this directory is only a
cmake folder and a
package.xml file, there are no more files/folders. Should I log an issue then?

By the way, it is possible to use this library for the turtlebot? or it is only for PR2 robot?
