This CMake presets file is useful when building SCORPIO with IDE tools like VSCode.

Setup Settings in VSCode,

• Ensure that CMake extensions are installed, CMake preset files are enabled (CMake:Use CMake Presets to "always" in Settings) and CMake generator is set to "Unix Makefiles" ("CMake:Generator" in Settings)
• Install CMake, MPICH and PnetCDF using Conda
• From your conda environment launch VSCode (code .)
• VSCode automatically reads the new CMake presets file

To configure SCORPIO from VSCode,

• Ctrl-Shift-P : Select "CMake: Select Configure Preset", choose "Linux Generic Machine (Debug)"

To build SCORPIO from VSCode,

• Ctrl-Shift-P : Select "CMake: Select Build Preset", choose "linux-generic-debug-build"
