#warning "Property macros are deprecated and will be removed after release 3.2. \
If you are not using property macros you can disable this warning by \
setting DUMUX_ENABLE_OLD_PROPERTY_MACROS to 0 (false) when configuring DuMux. \
DUMUX_ENABLE_OLD_PROPERTY_MACROS defaults to 1 (true) until release 3.1. \
After release 3.1 it will default to 0 (false) so you will have to manually \
enable property macros in order to use them."
