the warning is:
DEBUG: Executing python function do_transform_template
/build/../work/isar/meta/classes/template.bbclass:24: DeprecationWarning: invalid escape sequence '\$'

fix this by adding 'r' before opening quote in order to treat the string
as raw string, preventing the interpretation of backslashes as escape characters
