build.sh

#!/bin/bash
# Script to build all (or a part of) packages in e1039-core.
# Usage:
#   ./build.sh        ... Build all packages.
#   ./build.sh pkg    ... Build a single package "pkg".
#   ./build.sh -s pkg ... Build a single package "pkg".
#   ./build.sh -r pkg ... Resume building all packages from "pkg".
#   ./build.sh -i pkg ... Incrementally build "pkg" without clean up previous build.
#   ./build.sh [-c cmake_args] Optionally pass addtional cmake args to the build
#
# The 2nd usage is not recommended but kept available for backward compatibility for now.
#
# The "-b" option is useful in choosing "/dev/shm/$USER/core-build" for example to speed up the build process.
