Fix mksurfdata CMakeLists.txt: use SHARED for .so PIO libraries#3700
Merged

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 might as well go onto b4b-dev, so rebasing to it. |

Re-basing in github caused more files to be different. So I'll rebase in the branch. @cdevaneprugh I might need you to add me as a collaborator. |
This brings the parameter file in line with what I used for my AGU 2025 simulations.

Values differ:
[pft 61 (rice)] 0.4000000059604645 → 0.6

…remove dwat_temp as it's unused

I'm still seeing differences in other files after having done: git rebase b4b-dev fix/mksurfdata-cmake-shared-pio So we might need to cherry-pick just c1f13a6 to b4b-dev and/or wait until tomorrow when b4b-dev is merged up to master. |

@ekluzek will try this after b4b dev comes in and then try merging |
…rugh/CTSM into fix/mksurfdata-cmake-shared-pio

I made sure the build worked, so merging. |
