# This file is designed to setup reasonable defaults for the various settings so
# that configuring a build for a given platform is likely to build
# out-of-the-box without customization. This does not mean that it is the only
# way that will work, or that it represents a shipping configuration.
# User-specified configurations should be done through cache files or by setting
# the variable with `-DSwiftOverlay_*` on the commandline.

# Provide a boolean option that a user can optionally enable.
# Variables are defaulted based on the value of `<variable>_default`.
# If no such default variable exists, the option is defaults to `OFF`.
