[ros-users] Error compiling tutorial

[bdoshaughnessy]

Hi,

I'm new to ROS and am working my way through the tutorials but I'm receiving
an error while compiling the cylinder model segmentation example.  I created
the relevant file "segmentation_cylinder.cpp" in the proper location.  I
also added the two necessary lines of code to
/opt/ros/cturtle/stacks/point_cloud_perception/pcl/CMakeLists.txt.  The two
new lines are in bold below.  

Here is the entire CMakeLists.txt file:

I then run: sudo cmake
/opt/ros/cturtle/stacks/point_cloud_perception/pcl/CMakeLists.txt 

and this error occurs:

CMake Error at CMakeLists.txt:3 (include):
  include could not find load file:

    /core/rosbuild/rosbuild.cmake


CMake Error at CMakeLists.txt:6 (rosbuild_init):
  Unknown CMake command "rosbuild_init".


-- Configuring incomplete, errors occurred!

I have confirmed that the rosbuild.cmake is in the rosbuild folder.  I have
also hardcoded the location on the second line and received the same error. 
Any help would be greatly appreciated.

Thanks!
Brendan
