Moving to CMake 3.10.*

HDF5 Library
1

Could you elaborate on which configurations CMake current can NOT support and the failure mechanism under CMake? What are the motivations for moving to CMake 3.10? (I like new versions of CMake but does moving to CMake 3.10 actually solve any problems? It definitely helps on the Fortran side of things)

(Beating the dead horse...) and having a public place where developers can track the issue and provide fixes would help the community help you. At the moment, I have no way of knowing if someone else has tried to fix those issues or not. I would hate to put in a bunch of time on a fix and _then_ learn that someone else was already working on it.

All.

This year The HDF Group will be moving HDF software from CMake 3.2.* to CMake 3.10.1.

The reason is we are having too many issues reported with the current CMake version required to build HDF (HDF5, HDF4, HDFView, misc. tools, etc.)

Originally CMake was supported only for Windows, but now we have more and more users using CMake for building parallel, and Fortran configurations on non-Windows platforms. I.e., we need to come up with the solution that covers not only Windows and basic configurations of HDF. Said this we are welcoming any patches that will help us to finish the task.

We will keep you updated on our progress, and as usual, we will have updated software available for testing before the releases.

Thank you!

I follow the CMake mailing list to keep up on the changes that might improve the builds of hdf5. The biggest improvement in 3.10 was with MPI support. 3.9 improved support for configuration management. 3.8 through 3.10 has improved Fortran support. Packaging improvements have also been made in the later versions. Of course these are just my recollections from memory and not verified against the actual change notes (except for MPI - We tested the latest FindMPI code changes).
So the next 1.10 release provided the best opportunity to advance our CMake minimum.

I would like to upgrade the next 1.8 release to 3.10 as well, but could be talked back to an earlier version.
