#
# Description
#     Setup for PARAVIEW (partially cmake, qt too)
#
#     For system-wide cmake:            cmake_version=cmake-system
#     For system-wide qt:               ParaView_QT=qt-system
#
# Note
#     The following env. variables are required for building plugins:
#         ParaView_DIR
#         ParaView_INCLUDE_DIR
#         PV_PLUGIN_PATH
#
#     For central installations not located under ThirdParty, the environment
#     values must be set manually. For example,
#
#         setenv ParaView_DIR /opt/paraview/paraview-5.4.1
#         setenv ParaView_INCLUDE_DIR $ParaView_DIR/include/paraview-5.4
#         setenv PV_PLUGIN_PATH $FOAM_LIBBIN/paraview-5.4
#
#         setenv PATH ${ParaView_DIR}/bin:${PATH}
#         setenv LD_LIBRARY_PATH ${ParaView_DIR}/lib/paraview-5.4:${LD_LIBRARY_PATH}
#         unsetenv ParaView_VERSION     # avoid using ThirdParty settings
#
#     In newer versions (paraview 5.5), the contents of the lib/ changed
#     and now need to include that as well:
#
#         setenv LD_LIBRARY_PATH ${ParaView_DIR}/lib:${ParaView_DIR}/lib/paraview-5.5:${LD_LIBRARY_PATH}
#
