[CMake] CMake generated build number?

[J.S.Wijnhout at lumc.nl]

Hi,

Just a thought: Why don't you use the date and time? The compiler can provide those for you. We use two static functions for this:
const char *GetBuildDate ()
{
  return __DATE__;
}

const char *GetBuildTime ()
{
  return __TIME__;
}

Of course if you don't do a clean build, then the date and time won't get updated. In the past we used a different method, just passing the date and time through the compiler directly:
gcc -D`date +"%Y%m%d %H%M%S"`

Using the subversion revision number is also nice. For that, you could probably using the "exec_program" command that executes "svn info". After that you'll need some regex magic to retrieve the revision number from that.

best,

Hi, 

  I'd like to have a monotonically increasing "build number" auto generated by CMake.  This would be for official builds of the software, so we could track algorithm changes / results.  I'd also be happy if CMake could pull the latest SVN revision number.  This would go in a -D during the build.

Any clues how to do this? 

Thanks,
