This should work if there is exactly one thing that depends on the output of this custom command. If multiple things start depending on the generated files, you may end up with weird results. See:

Instead, use the [add_custom_target()](https://cmake.org/cmake/help/latest/command/add_custom_target.html#command:add_custom_target) command to drive the command and make the other targets depend on that one. See the [Example: Generating Files for Multiple Targets](https://cmake.org/cmake/help/latest/command/add_custom_command.html#example-generating-files-for-multiple-targets) below.
