catkin make and running hrl_tilting_hokuyo

edit

I'm running hydro and switching over from new rosbuild to using catkin. I read through the catkin conceptual overview and tutorials but have trouble implementing.

I'm trying to get the tilting hokuyo set up. I 'catkinized' the hrl_hardware_drivers but having trouble with the hrl_lib. It wasn't included in the package so I found it externally. When I run:

rosrun hrl_hokuyo hokuyo_processing.py

It goes me the error:

src/hrl_hokuyo/hokuyo_processing.py", line 43, in <module> import hrl_lib.transforms as tr ImportError: No module named hrl_lib.transforms

I believe the cmakelist and package.xml file was edit appropriately to include hrl_lib. I want to do it right and not just add the hrl_lib folder into the directory.

Thanks!

Heres is the cmake

cmake_minimum_required(VERSION 2.8.3)
project(hrl_hokuyo)

find_package(catkin REQUIRED COMPONENTS hokuyo_node sensor_msgs rospy hrl_lib)

set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)

catkin_package(
    DEPENDS hokuyo_node sensor_msgs rospy hrl_lib
    CATKIN_DEPENDS # TODO
    INCLUDE_DIRS # TODO
    LIBRARIES # TODO
)

Here is the package.xml

<package>
  <name>hrl_hokuyo</name>
  <version>1.0.0</version>
  <description>Python class that uses hokuyo_node from ros-pkg to get scans from
  UTMs and player to get scans from URGs.</description>

Edit #1

I'm still having trouble with it. Is the hrl_lib package just a folder with the python files in it? This doesn't feel right since there are other folders with the library as well. Here is my structure:

/path_to_workspace/
    /src
        /hrl_hokuyo
            /setup.py
            /src
                /hrl_hokuyo
                /hrl_lib

Thanks for the quick response and breaking it down for me.

Edit#2

I didn't edit it much except just setting the path.

from distutils.core import setup
from catkin_pkg.python_setup import generate_distutils_setup

d = generate_distutils_setup(
    packages=['hrl_lib'],
    package_dir={'/path_to_directory_containing_hrl_lib/': 'src'}
)

setup(**d)
