Building from source fills up /tmp

We have a user request for this software on our cluster. I am following the instructions https://github.com/LLNL/COGENT/tree/master?tab=readme-ov-file#install-instructions specifically starting from the NERSC template.

In `Make.defs.local` I set:
```
CXX=gcc
FC=gfortran (also tried mpif90)
MPICXX=mpicxx
```

I was able to build hypre in step 3, but not COGENT in step 4 as it fills up our entire `/tmp` disk space (>180G). Is this the expected behavior and, if so, how much space should we allocate for `/tmp`?

Review the install instructions and the reported settings in Make.defs.local, focusing on step 4 after hypre builds successfully. Reproduce the COGENT build while monitoring /tmp usage and determine whether the growth is expected or indicates a build problem. Done means documenting the required temporary space or identifying the build behavior that needs correction.
