It is also possible embed a generated file::
add_custom_command(OUTPUT my_processed_file.bin
COMMAND my_process_file_cmd my_unprocessed_file.bin)
target_add_binary_data(my_target "my_processed_file.bin" BINARY)
In the example above, ``my_processed_file.bin`` is generated from ``my_unprocessed_file.bin`` through some command ``my_process_file_cmd``, then embedded into the target.
To specify a dependence on a target, use the ``DEPENDS`` argument::
add_custom_target(my_process COMMAND ...)
target_add_binary_data(my_target "my_embed_file.bin" BINARY DEPENDS my_process)
The ``DEPENDS`` argument to ``target_add_binary_data`` ensures that the target executes first.
