package 'libopenni' not found - OPENNI_INCLUDE_DIRS problems

Hi All, I am slowly making progress towards getting laser_scan_matcher installed on rasp pi. I have all the pcl dependencies complied Problem I am now faced with a dependency when compiling the laser_scan_matcher itself. I've build openni and installed it but catkin_make is giving the following errors - even though I've exported the dir's for OPENNI_INCLUDE_DIRS -- +++ processing catkin package: 'scan_to_cloud_converter' -- ==> add_subdirectory(scan_tools/scan_to_cloud_converter) -- Using these message generators: gencpp;genlisp;genpy -- checking for module 'libopenni' -- package 'libopenni' not found -- Could NOT find openni (missing: OPENNI_INCLUDE_DIRS) -- The imported target "vtkWrapTcl" references the file "/usr/bin/vtkWrapTcl" but this file does not exist. Possible reasons include: * The file was deleted, renamed, or moved to another location. * An install or uninstall procedure did not complete successfully. * The installation package was faulty and contained "/usr/lib/vtk-5.8/VTKTargets.cmake" but not all the files it references. Anyone any ideas? Thanks Mark
