Turtlebot Arm Installation / Catkin Error

edit

Hi,

Another one I've been faffing about trying to figure out why I can't get it to compile / make.

Anyway, I have been trying to install the Turtlebot Arm package from fergs

https://github.com/turtlebot/turtlebot_arm

Admittedly on Hydro ros, and I keep getting an error during catkin_make.

-- +++ processing catkin package: 'turtlebot_block_manipulation'
-- ==> add_subdirectory(turtlebot_arm/turtlebot_block_manipulation)
CMake Error at /opt/ros/hydro/share/catkin/cmake/catkinConfig.cmake:72 (find_package):
  Could not find a package configuration file provided by "pcl" with any of
  the following names:

    pclConfig.cmake
    pcl-config.cmake

  Add the installation prefix of "pcl" to CMAKE_PREFIX_PATH or set "pcl_DIR"
  to a directory containing one of the above files.  If "pcl" provides a
  separate development package or SDK, be sure it has been installed.

-- Configuring incomplete, errors occurred!
make: *** [cmake_check_build_system] Error 1
Invoking "make cmake_check_build_system" failed

Now i've tried a number of things like git cloning various pcl's or pcl-1.7s into catkin_ws/src and making them but it has no effect.

From what I can tell the original hydro-desktop install has both pcl and pcl-1.7 folders, and within pcl-1.7 is a PCLconfig.cmake file, it just seems to not be found or have no effect.

Anyone have a good idea of what to do next?

Any help is appreciated as I'm a bit lost on this one
