MAPL 2.66.0

[mathomp4]

This release of MAPL is mainly for a fix in some sorting code used in GEOS for our boundary condition construction. An integer overflow was found at very-high resolution.

Beyond that are minor infrastructure updates to ESMA_env and ESMA_cmake as well as our beginning efforts at using ML agents with MAPL development.

This is zero-diff to MAPL v2.65

---

This version of MAPL was tested with:

• Intel Fortran Classic (ifort) 2021.13
• Intel Fortran (ifx) 2025.3
• GCC 13.2.0, 14.2.0, and 15.2.0
• NAG 7.2

The libraries this version of MAPL is currently tested with are below.

• Baselibs 8.24.0
  • netcdf-c 4.9.2
  • netcdf-fortran 4.6.1
  • ESMF 9.0.0b08 (Note: MAPL only requires 8.6.1 at the moment)
  • GFE 1.20.0
    • gFTL 1.16.0
    • gFTL-shared 1.11.0
    • pFUnit 4.13.0 (optional)
    • fArgParse 1.10.0 (if -DBUILD_WITH_FARGPARSE=YES, default=YES)
    • pFlogger 1.17.0 (if -DBUILD_WITH_PFLOGGER=YES, default=YES)
  • UDUNITS2 2.28.8

Also, if you build with Baselibs and/or -DUSE_F2PY=ON, you should use (at least):

• ESMA_cmake v3.72.0

We recommend most external users set -DUSE_F2PY=OFF

We also require CMake 3.24 or higher.
