It doesn't sound reasonable to do so, but probably I don't fully 
understand what you're up to.

For md5 you might use cmake -E md5sum
For others you have to use external tools.

You might play with add_custom_target and add_custom_command.

But
- this is not a cmake list
- I doubt that it's worth the effort since it is simple to
   handcraft a Portfile.
