### Copy rules
#   Copy files from the installation directory to the staging directory,
#   ready to be packed.
# Targets are executed in the following order:
#  copy_msg_target
#  pre_copy_target   (override with PRE_COPY_TARGET)
#  copy_target       (override with COPY_TARGET)
#  post_copy_target  (override with POST_COPY_TARGET)
# Variables:
#  STAGING_DIR:      Files will be copied in this directory
#  DEPENDS:          List of dependencies, used to build $(WORK_DIR)/PLIST 
# Files:
#  $(WORK_DIR)/PLIST List of files to copy to the staging directory
