[Paraview] Building a ParaView plugin

[John Haiducek]

Thanks for the tip, Utkarsh.

Now I'm having some difficulty with CMake (I've not used CMake enough to get
comfortable with it yet).

My CMakeLists.txt is:

cmake_minimum_required(VERSION 2.8)
 FIND_PACKAGE(ParaView REQUIRED)
 INCLUDE(${PARAVIEW_USE_FILE})

ADD_PARAVIEW_PLUGIN(AddTetraLayer "1.0"
  SERVER_MANAGER_XML vtkAddTetraLayer_SM.xml
  SERVER_MANAGER_SOURCES vtkAddTetraLayer.cxx
  GUI_RESOURCE_FILES vtkAddTetraLayer_GUI.xml)


When I do a "generate" in ccmake, I get this:

 CMake Warning at
/usr/local/lib/paraview-3.8/CMake/ParaViewPlugins.cmake:986 (ADD_LIBRARY):
   Cannot generate a safe runtime search path for target AddTetraLayer
because
   files in some directories may conflict with libraries in implicit
   directories:

     runtime library [libQtCore.so.4] in /usr/lib64 may be hidden by files
in:
       /usr/local/lib/paraview-3.8

   Some of these libraries may not be found correctly.
 Call Stack (most recent call first):
   CMakeLists.txt:9 (ADD_PARAVIEW_PLUGIN)


I am then able to build in spite of the error, but the output looks like:

[  9%] Generating qrc_AddTetraLayer.cxx
[ 18%] Generating vtkSMXML_AddTetraLayer.h
/usr/local/bin/kwProcessXML: error while loading shared libraries:
libvtkCommon.so.pv3.8: cannot open shared object file: No such file or
directory
make[2]: *** [vtkSMXML_AddTetraLayer.h] Error 127
make[1]: *** [CMakeFiles/AddTetraLayer.dir/all] Error 2
make: *** [all] Error 2

Can anyone tell me how to fix these errors?
