Neither of those "issues" occurs if you have set up add_custom_command
and the corresponding add_custom_target with the appropriate
dependencies between them.

If re-reading the CMake documentation for add_custom_command and
add_custom_target doesn't help, then I suggest you give a simple example
that is not working for you.  I assume you have some dependency
issue, but until you give an example, it is hard to anticipate what
that might be.
