[Paraview] PythonQt build error

[Christoph Willing]

Thanks for looking at it so quickly. However that change doesn't fix it 
for me. Here's some of the session:

- first confirm that change (addition of "include(ParaViewQt)" is applied:
root at sl64-142-vmbuilder:/tmp/SBo/ParaView-v5.2.0/build# head -13 
/tmp/SBo/ParaView-v5.2.0/Plugins/PythonQtPlugin/CMakeLists.txt
if (ParaView_SOURCE_DIR)
else()
   cmake_minimum_required(VERSION 3.3)
   project(PythonQtPlugin)

   find_package(ParaView REQUIRED)
   include(${PARAVIEW_USE_FILE})
endif()


include(ParaViewQt)
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} ${CMAKE_CURRENT_SOURCE_DIR})
find_package(PythonQt REQUIRED)

- yes, patch applied so try make:
root at sl64-142-vmbuilder:/tmp/SBo/ParaView-v5.2.0/build# make -j1
.....
[ 99%] Generating moc_pqPythonQtPluginImplementation.cxx
/bin/sh: Qt4::moc: command not found
Plugins/PythonQtPlugin/CMakeFiles/PythonQtPlugin.dir/build.make:62: 
recipe for target 
'Plugins/PythonQtPlugin/moc_pqPythonQtPluginImplementation.cxx' failed
make[2]: *** 
[Plugins/PythonQtPlugin/moc_pqPythonQtPluginImplementation.cxx] Error 127
CMakeFiles/Makefile2:45361: recipe for target 
'Plugins/PythonQtPlugin/CMakeFiles/PythonQtPlugin.dir/all' failed
make[1]: *** [Plugins/PythonQtPlugin/CMakeFiles/PythonQtPlugin.dir/all] 
Error 2
Makefile:149: recipe for target 'all' failed
make: *** [all] Error 2


So I still have a failure, even with the change in place. If I edit the 
offending file 
Plugins/PythonQtPlugin/CMakeFiles/PythonQtPlugin.dir/build.make and 
change all instances of "Qt4::moc" to plain "moc", then compilation 
carries on to completion:
