# Call this script from the root project directory via `make dist`
# - submodules will be recursively initialized and updated
# - patches will be applied to submodules if needed
# - this script will call CMake to generate library-building packages if necessary
# - once projects have been generated, this script will use their tooling to build the libraries/packages
# - when all products have been built and moved to `tmp`, they will be compressed and moved to `products`
