[Trilinos-Users] [EXTERNAL] [Trilinos-developers] Upgrade minimum CMake version from 2.8.11 to 3.3.2?

One issue here is ensuring we still have these tools available on the Cray and IBM platforms moving forward. I’m not sure what the minimum will be for Trinity on the final production O/S but it is difficult for all of our users to build their own on these machines.

Might we just upgrade our builders and not set this as a minimum requirement?

The reason is that we have a minor patched version of CMake 3.3.2 [1] that runs 3x to 4x faster than CMake 2.8.11.  This will allow us to speed up our automated testing for Trilinos and make developers more productive.
