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

[Satish Balay]

This build is with --with-cxx=0 - so .cxx source-files shouldn't get compiled.

I'm not sure what the mechanism we have for disabling compile of cxx sources when --with-cxx=0 is used.

Checking -  I see most of the cxx sources are tied to external-packages - and the corresponding package configure enforces c++ requirement

How is kokkos enabled? Is there no --download-kokkos [or equivalent] needed in configure for kokkos?

Note --with-cxx=0 - likely g++ is somehow getting picked up here [ with /usr/include/stdio.h] - resulting in failure
