There are several approaches.  Here are two:

1.) Build the contents of the variable with newlines instead of 
semicolons, or transform the contents like this:

SET(CONTENTS "")
FOREACH(line MYLINES)
   SET(CONTENTS "${CONTENTS}${line}\n")
ENDFOREACH(line)

2.) Use the STRING command's REGEX option to replace semicolons with 
newlines.
