 more additional info:



 from http://www.mail-archive.com/cmake@cmake.org/msg07252.html
 {{{
 # ^ and $ appear to be non-functional in practice. This makes it
 # impossible to code a non-trivial regex in CMake script.  This in turn
 # forces the user to find or install other tools that can do so, rather
 # than keeping their scripting logic self-contained in CMake.
 #
 # ^ and $ work work with respect to an entire <input> to STRING().
 # That is to say, an <input> is treated as one line.  The <input>
 # does not preserve newlines, even if it is read from a multi-line file.
 # The following code snippet demonstrates that ^ and $ will only
 # match at the beginning and end of a file, when the file is read in as
 # an <input> string.
 }}}

 one that was suggested was

 {{{
  STRING(REGEX REPLACE "\r?\n" ";" ENT "${input}")
  FOREACH(line ${ENT})
  # do the match on each line

 }}}
