Using External Libraries in HDK

I am using HDK to make a SOP that will perform a concave hull function on a given set of points.
I am attempting to use an external library, Point Cloud Library (PCL) []
However, when I build the hdk node I run into a problem.
It compiles just fine but does not actually come up in houdinifx.
This seems to be caused by a constructor of a class in PCL on line 94.
When I comment out this section, referring to the pcl::ConcaveHull… chull, the node compiles and is visible in houdinifx.
I attached the file.

Does anyone know if I am missing something that I should be doing in order to use this library.
I know it has quite a few dependencies of its own, but I have gone through and installed all those as well.
Any help would be much appreciated.

Sometimes these failures are path related. Make sure the library you are linking to your SOP is in PATH or is visible to Houdini otherwise.
