SCR caches checkpoint data in storage on the compute nodes of a Linux cluster to provide a fast, scalable checkpoint / restart capability for MPI codes.
Now that users tend to install SCR directly, it would be better to define the system config file path to be some location within the install directory, where a normal user could actually create such a file. This saves most users from having to set -DSCR_CONFIG_FILE at build time to do the same.
This will require some changes to cmake and to respective documentation.
When we were installing SCR for users, it made sense to use a system directory for the default config file.
