Good question.  The dependency information is used by CMake (at CMake time)
to configure a custom command to be run at build time with the correct
dependencies.  Thus, the answer to your question must be that build time is
too late to collect the dependency information used by CMake.  Instead, you
must do that at CMake time like I outlined.
