Super easy to fix - go to ThirdParty/exodusII/vtkexodusII/src/ex_create_par.c and ThirdParty/exodusII/vtkexodusII/src/ex_open_par.c and replace
const char exodus_unused_symbol_dummy_1;
with
const char exodus_unused_symbol_dummy_ex_create_par;
should solve your compile issues!
You can also go to ThirdParty/exodusII/update.sh and change the tag to readonly tag="for/vtk-20200128-7.24f-v2019-12-18"
