Sorry about that Brad, for some reason I didn't get your last response
in my inbox. It's not in spam either. Strange.

I like your idea of using an external script to handle this, however,
there is certain state I need access to from the last CMake run.
Specifically, I have a variable with all of the 'bin' directories
where DLLs can be found. To avoid recursive searching in my custom
target script to find them each time I build, I suppose I could store
them in a cache variable? I was just going to create a CMake script
that I run from the custom target.

The reason I went with custom commands to begin with is because I
originally used cmake's copy_if_different command, but it turned out
to be MUCH slower than the out of date checks that the custom command
did.
