* Hydrogen now depends on `aluminum +nccl` vs. `aluminum +mpi_cuda`
* Hydrogen: Simplify Mac OS OpenMP-detection logic
* Aluminum: Add Mac OS OpenMP-detection logic
* LBANN: depend on conduit@0.4.0: instead of conduit@master
* Added a package for the MDAnalysis toolkit.
* Updated LBANN, Hydrogen, and Aluminum to not require CUDA-aware MPI
even when using CUDA. Fixed small bugs within both LBANN and Hydrogen
packages. Added requirements for breathe and cereal to LBANN.
* Update use case for doc dependencies.
* Cleaning up some of the LBANN software stack dependencies.
Updated LBANN, Hydrogen, and Aluminum to not require CUDA-aware MPI
even when using CUDA. Fixed small bugs within both LBANN and Hydrogen
packages. Added requirements for breathe and cereal to LBANN.
* Added a package for the MDAnalysis toolkit.
* Added Ninja as the generator for LBANN, Hydrogen, and Aluminum. Also
fixed a bug in how the Conduit variant is included in LBANN. Added
new versions for Hydrogen and LBANN.
* Updated lbann package so that the CMAKE parameters are set when the
variant is on and off.
* Added support for the Aluminum library to LBANN and Hydrogen. Also
fixed several bugs in the grouping of dependencies of both packages.
* Updated the conduit package to have the proper dependency on the
python variant.
* Added new versions for NCCL
* Fixed a bug in how Hydrogen set the path for OpenBLAS.
* Added support for conduit in LBANN.
