# Your build script should simply source this script, optionally override any build hooks and then invoke `build`.
# The build product should be available under `build-<platform>~/out`, under the library path.
#
# Hook lifecycle:
# - build
# - initialize
# - needs
# - clean & exit (only if script was ran with "clean" argument)
# - prepare
# - clean
# - config
# - target
# - prepare
# - configure
# - build
# - finalize
# - merge
# - clean
#
# You can override any of these hooks to provide a custom implementation or call their underscore variant to delegate to the default implementation.
# For example:
# target_prepare() { make -s distclean; }
# target_configure() { _target_configure "$@" --enable-minimal; }
