Requires cime6.1.137
The CMakeLists.txt declares PIO libraries as STATIC IMPORTED but then points to shared library files (.so). This is an internal inconsistency that can cause build failures when using externally-built shared PIO libraries. Fix: Change STATIC IMPORTED to SHARED IMPORTED for pioc and piof targets since they reference .so files. Tested on: HiPerGator (UF HPC) with GCC 14.2.0, OpenMPI 5.0.7, shared PIO 2.6.6 at /blue/gerber/earth_models/shared/parallelio/bld/
This brings the parameter file in line with what I used for my AGU 2025 simulations.

…remove dwat_temp as it's unused

ifx apparently doesn't do short-circuit evaluation, so SMS_D_Ld1.ne30pg3_t232.I1850Clm50BgcSpinup.derecho_intel.clm-cplhist was crashing with floating invalid when using the ifx compiler (via ccs_config_cesm1.0.75). Resolves ESCOMP#3763

Fixes for ifx
Address C-cycle + fire biases in CESM3 runs by updating nml defaults - New defaults for lnd_tuning_mode="clm6_0_cam7.0" defo_fire_precip_thresh_bet = 1.4d00 rh_hgh = 80.0d00 - New default paramfiles for clm6: /glade/work/linnia/CLM6-PPE/ctsm6_cal/paramfiles/ctsm60_params.c260204.nc for lnd_tuning_mode="clm6_0_cam7.0": /glade/u/home/slevis/paramfiles/iss3725_forFang/ctsm60_params.c260204.cesm3-01.nc The latter got renamed to ctsm60-cam70_params.c260204.nc and it increases pft-specific values of "rswf_max" and "rswf_min" - New default finidat for ne30 and 1850 /glade/derecho/scratch/wwieder/archive/ctsm5.4.015_BGCcrop_ne30_144_pSASU/rest/0181-01-01-00000/ctsm5.4.015_BGCcrop_ne30_144_pSASU.clm2.r.0181-01-01-00000.nc All new files got moved to /inputdata and got rimported. Issue ESCOMP#3725 PR ESCOMP#3756 Changes answers relative to baseline in Clm6 cases: - Nature of change: larger than roundoff due to changes in defaults - LMWG_dev issue number(s): NCAR/LMWG_dev#141 NCAR/LMWG_dev#143
