Get standard Trilinos CI build working with SEMS env with CMake 3.3+ on RHEL 7
Created by: bartlettroscoe
The SEMS env for the GCC 4.7.2 stack used by the standard Trilinos CI build (#482 (closed)) fails with CMake 3.3+ on RHEL 7 machines (see #945 (closed)). This story is to find a way to fix things so that this env works out of the box on RHEL 7 without hacks.
