You do not need the single quotes surrounding the here-script.  It is 
CMake's responsibility to pass the arguments on the generated command 
line with proper escaping.  Without the quotes the shell will expand one 
level of escapes and perl will get the proper script.  However, CMake 
may not currently escape all text properly for all shells.  I suggest 
you configure the script into a file and then run perl on that file.
