Instead of reading the whole file using file(READ) and later matching on the whole file use file(STRINGS ... REGEX) to get only those lines we are interested in at all. This will make the list much smaller (good for debugging) and also the regular expressions will need to match on much smaller strings. Also unset the content variables once they are not used anymore.
