The C++ headers are missing on ppc64le. On other architectures, they
are in /usr/include/openmpi-<arch>/openmpi/ompi/mpi/cxx. The cxx
subdirectory does not exist in the ppc64le build. Indeed, if you look
at build.log from the latest openmpi build on ppc64le, you'll find
this line:
checking if want C++ bindings... no
You might want to contact the openmpi package maintainers to find out
if that is deliberate or an accident.
Regards,
Indeed, this was deliberate, but should have been reverted long ago:

- Temporarily disable C++ bindings on ppc64/ppc64le (#1388561)

I'm working on getting this fixed at least in rawhide.
