This name is used as variable prefix, # and the targets generated are listed in a variable by that name. # # Remaining parameters are named arguments. These include: # SOURCE_DIRS one or more directory roots to search for files to process # SOURCE_FILES complete paths to one or more files to process # OUTPUT_DIR the directory where we store the processed files. # OUTPUT_FILE the name of the resulting file. Only allowed if processing a # single file. # SOURCE_BASE_DIR a common root to all SOURCE_DIRS or SOURCE_FILES. # If specified, files will keep the path relative to the base in the # OUTPUT_DIR. Otherwise, the hierarchy will be flattened into the OUTPUT_DIR. # INCLUDE_FILES only include files matching these patterns (used only with # SOURCE_DIRS) # EXCLUDE_FILES exclude files matching these patterns (used only with # SOURCE_DIRS) # INCLUDES replace the occurrences of a pattern with the contents of a file; # one or more such include pattern, using the syntax: # PLACEHOLDER => FILE_TO_INCLUDE ; ... # Each PLACEHOLDER must be on a single, otherwise empty line (whitespace # padding is allowed). # REPLACEMENTS one or more text replacement patterns, using the syntax: # PATTERN => REPLACEMENT_TEXT ; ... # # If both INCLUDES or REPLACEMENTS are present, then the includes will be # processed first, and replacements will be done on the included fragments as well. # If neither is present, the files will just be copied without modifications. #
