You can't just say COMMAND like that. I'm sure CMake told you that,
right?

You need an add_custom_command(), probably a POST_BUILD step. Look in
the docs for add_custom_command and in the FAQ at the sections about
generating headers.

Oh, and you probably want -E copy_if_different. This will likely save
you some unnecessary rebuilds down the line.
