[CMake] ADD_DEFINITIONS with output from shell

[David Sveningsson]

Hi, I am converting some makefiles for a large application. One of the 
makefiles adds the following to CFLAGS:

-DSVN_REVISION="\"`svn info|grep Revision| awk '{print $2}'`\""

(it runs some shell commands which will output the current subversion 
revision)

I tried searching for a way for cmake to run the above command but I 
found nothing. Is there a way to accomplish this?
