Summary0006285: File-level versus target-level dependencies for custom commands
DescriptionConsider a chain of custom commands:

  in.txt -> out1.txt -> out2.txt

Assume they are placed in targets

  add_custom_target(custom1 DEPENDS out1.txt)
  add_custom_target(custom2 DEPENDS out2.txt)

The rule for out1.txt will be pulled into custom2 via out2.txt's dependency on it. In a parallel build the rule for out1.txt might be run twice simultaneously.

In order to avoid this, one must write

  add_dependencies(custom2 custom1)

However we should be able to compute and add this dependency automatically.

We should be able to keep some kind of table to know that out1.txt has been explicitly listed in target custom1. When tracing the depenencies in target custom2 for out2.txt it should recognize that in order to get out1.txt it should add the target-level dependency on custom1 instead of pulling in the rule.

Sending issues I'm not actively working on to the backlog to await someone with time for them.

If an issue you care about is sent to the backlog when you feel it should have been addressed in a different manner, please bring it up on the CMake mailing list for discussion. Sign up for the mailing list here, if you're not already on it: [^]

It's easy to re-activate a bug here if you can find a CMake developer or contributor who has the bandwidth to take it on.
