The script now writes out a separate script that can be used to set up the build environment to $ROOT_DIR/share/env.sh. This can be sourced in a shell to set up the build environment or it can be given a command to directly execute in the environment. This makes it easier to build Clutter from your own source rather than checking it out from git directly.
