# The list of all source files is returned in $1_SOURCES.
#
# Remaining parameters are named arguments. These include:
#   SRC     : Source root dir (defaults to dir of first file)
#   DEST    : Dest root dir
#   FILES   : List of files to copy with absolute paths, or path relative to SRC.
#             Must be in SRC.
#   FLATTEN : Set to flatten the directory structure in the DEST dir.
#   MACRO   : Optionally override the default macro used for making the copy.
#             Default is 'install-file'
#   NAME_MACRO : Optionally supply a macro that rewrites the target file name
#                based on the source file name
#   LOG_ACTION : Optionally specify a different action text for log messages
