# This is the target config to import when building for host. All this does is
# import the appropriate target configuration for the current host OS.
#
# Due to GN-isms, lowest-precedence target variable definitions must be imported
# at the deepest point. This causes the following structure:
#
# target_system.gni (e.g. Linux)
#         └ host_common.gni
#                  └ pw_vars_default.gni
#
# This allows host_common to override variables defined in pw_vars_default,
# and target_system to override defaults in host_common.

# Load target-specific config file for a host desktop system.
