add_rpath_flag(lib_path, rpath_filter, rpath_lib_paths, cmd_args_rpath, ldflag_prefix)

Add an -rpath flag for the given library path if it is valid and not a duplicate. Don't RPATH in empty or relative paths, or paths that are filtered out; linking relative paths via RPATH doesn't make much sense and it can also break the build because it may result in reordering lib paths.

PARAMETER	DESCRIPTION
lib_path	Library path to process
rpath_filter	Compiled regex filter for excluding paths
rpath_lib_paths	List of already processed library paths
cmd_args_rpath	List of -rpath flags to append to
ldflag_prefix	Prefix for linker flags (e.g., '-Wl,' or empty)

is_new_existing_path(new_path, paths)

Check whether specified path exists and is a new path compared to provided list of paths (that surely exist as they were checked before).

PARAMETER	DESCRIPTION
new_path	The new path to check
paths	The list of existing paths
