I am curious to understand why we are seeing this recent set of build errors that are killing nightly testing.

@spdomin I can't see anyway that either commit could be causing that. Can you post the output from the cmake configure process? That might give a hint as to why mpi.h isn't being found.

I know, I was processing a bisect and saw that there were no relevant changes besides a seacas change.

Let me simply re-process a build and test and see what happens. Perhaps a module was simply not found during the nightly process.

It looks like there was a module issue and openmpi was not loaded properly. The tests this AM ran without issue. Thanks for looking at this @jhux2, and apologies for the false positive.
