Hi Ankur,

You're using the correct patch (the rosintegration-v2 patch.)  It was
created against PCL 1.6.0, so it should apply cleanly when using the
current srpm.  I tried it last night, and it seems to be working OK (I
didn't sit through the whole build process though, just through CMake
and the first couple files)

You do have to do a couple of extra steps after you apply the patch
though.  First, you need to source /path/to/ros/setup.sh at the
beginning of the %build section.  Then you need to add -DUSE_ROS=ON to
the CMake command.  You should see some CMake output along the lines
of "Found ROS, using ROS" during the build.

The build that I tried last night was against the ROS Fuerte underlay
from my copr[1], if you're interested I could create a ros-fuerte-pcl
srpm and build it there pretty easily.
