rem ============================================================================
rem build.bat - KEnRef build orchestrator (Windows)
rem
rem Windows builds kenref_core ONLY. The MD engines KEnRef plugs into -- PLUMED
rem and GROMACS -- target Linux/macOS (autotools PLUMED, `plumed patch`, the
rem GROMACS force provider); they are not built here. For the full
rem kenref_core -> PLUMED -> GROMACS chain use build.sh on Linux/macOS/WSL.
rem
rem Toolchain specifics come from the environment (CXX/CC/CXXFLAGS) or your
rem CMake generator; this script keeps only portable defaults.
