`>> ParaView_INCLUDE_DIR` isn’t necessary
anymore. Instead, just link to `ParaView::Catalyst`
`I am missing something. I need````ParaView\_INCLUDE\_DIR at compile time.`I` have files which e.g. “#include
\”. How can I compile my code
without```ParaView_INCLUDE_DIR?``
`` On another topic, at link time I hit issues I do not
have when link to a Catalyst build. I get ’ undefined
reference to `\_PyUnicodeUCS2…’. I wonder if it relates
to the system python, or I am missing a PYTHONPATH ?
Paraview-config.cmake doesn’t
set PARAVIEW\_PYTHONPATH,
– PARAVIEW\_ENABLE\_PYTHON= ON
```````
-- PARAVIEW_PYTHONPATH =
``````
```````
and paraview CMakeCache.txt is correct:
```
Python2_EXECUTABLE
```
/ascldap/users/tesari/local/python-2.7.16/bin/python2.7
```
Python2_INCLUDE_DIR
```
/ascldap/users/tesari/local/python-2.7.16/include/python2.7
```
Python2_LIBRARY_RELEASE
```
/ascldap/users/tesari/local/python-2.7.16/lib/libpython2.7.so
Could you advise, please?
```
.../build/lib64/libvtkWrappingPythonCore-pv5.6.so.1:
```
undefined reference to `\_PyUnicodeUCS2\_AsDefaultEncodedString’
```
.../build/lib64/libvtkPVCinemaReader-pv5.6.so.1: undefined
```
reference to `PyUnicodeUCS2\_AsLatin1String’

I figured out why I got “undefined reference to
`\_PyUnicodeUCS2\_AsDefaultEncodedString’”. The reason was
that RPATH in the shared objects listed
both, the build path and the install path. Linker
issued warnings of ‘circular dependencies’, and that not all
shared objects may be resolved correctly (don’t have the exact
screenshot). In order to brake the circular dependencies I set CMAKE\_SKIP\_RPATH=ON ,
but the build path was still listed in
RPATH. I had to set both, CMAKE\_SKIP\_INSTALL\_RPATH=OFF
and CMAKE\_SKIP\_RPATH=OFF
, and to set LD\_LIBRARY\_PATH
,to make it work. Is this the right way to install a
paraview build?

> I am missing something. I need ParaView\_INCLUDE\_DIR
You’re missing `target_link_libraries(yourtgt PRIVATE VTK::CommonDataModel)` (could also be `PUBLIC` depending on how you’re using it) for that header.
> UCS2 problems
It seems to me that ParaView was built against a UCS2 Python build, but is finding a UCS4 Python build when you’re linking to ParaView.
