I can fill this in.

Installing and working with PCL standalone, means that you use it as you would use any other system library, like Boost. 
We provide a proper standard cmake FindPCL/PCLConfig set of files, which means that you can simply use things like:

{{{
find_package(PCL 1.0 REQUIRED)

include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})

add_executable (FOO FOO.cpp)
target_link_libraries (FOO ${PCL_LIBRARIES})
}}}


Again, all of these things are _very_ well documented on our web pages. ;)


Whenever you mix and match different libraries (PCL from ROS with PCL standalone), you're guaranteed to run into issues, 
hence Ivan's e-mail about the segfault, and my reply about trying his code first with PCL standalone, to see if we have 
a bug in PCL, or whether it's a "mix-up" issue.


Cheers,
Radu.
