[petsc-dev] Windows error in pipeline with cxx file

[Satish Balay]

And if kokkos won't have a configure option - and would always work with any c++ compiler - you can use:

diff --git a/src/dm/impls/plex/landau/kokkos/makefile b/src/dm/impls/plex/landau/kokkos/makefile
index 04504b4bf5..faa59fe0ff 100644

 -include ../../../../../../petscdir.mk

[with corresponding #ifdef wrappers for all calls to functionality in these sources]
