  +libCEED support
  +---------------
  +- Added support for libCEED, the portable library for high-order operator
  + evaluation developed by the Center for Efficient Exascale Discretizations in
  + the Exascale Computing Project, https://github.com/CEED/libCEED.
  +
  +- This initial integration includes Mass and Diffusion integrators. libCEED GPU
  + backends can be used without specific MFEM configuration, however it is highly
  + recommended to use the "cuda" build option to minimize memory transfers.
  +
  +- Both CPU and GPU modes are available as MFEM device backends (ceed-cpu and
  + ceed-cuda), using some of the best performing CPU and GPU backends from
  + libCEED, see the sample runs in examples 1 and 6.
