[CMake] Writing a list variable to file

[Ian.Appru at ubs.com]

Hi Brad 

1) works well - thanks 
   the MESSAGE cmd won't print it which made me doubt it was working

2) doesn't work since the ; seps are removed before the regular
expression is applied

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.
