This repository is simply used to build the packages that Xyce depends on, followed by Xyce.
The installation directory is specified by the environment variable
XYCE_INSTALL. This directory is used to install SuiteSparse, Trilinos,
as well as Xyce. If this environment variable is not set, then it is set
to ACT_HOME.
The latest Trilinos requires a modern cmake version (at least 3.29).
Some standard package managers install older versions of cmake. If that is
the case, the build scripts attempt to install a newer version of cmake
in the default installation path for cmake.
