build.sh

#!/usr/bin/env bash
# build.sh — drive builds via CMakePresets.json
#
# Examples:
#   ./build.sh --list
#   ./build.sh linux-gcc-debug/release
#   ./build.sh macos-gcc-debug/release
#   ./build.sh riscv32-gcc-debug/release (this option only works on Linux with installed cross compiler)
#   ./build.sh --configure linux-gcc-debug --build linux-gcc-debug --fresh
#   ./build.sh macos-gcc-debug --archive lib/libgncAlgorithms.a
#
# Notes:
# - Uses your CMakePresets.json configure/build presets.
# - --fresh uses CMake's native reconfigure (CMake >= 3.24).
# - The script chooses a sensible default preset if none is provided.
