According to the docs, the DEPENDS arguments for add_custom_command() support generator expressions. I was surprised to see that the similar DEPENDS argument for add_custom_target() is not documented as supporting them. Is that a documentation oversight, or does add_custom_target() not formally support them for DEPENDS arguments after all?

Hmm…I’d add a test and update the docs based on the results. If the test fails…well, that’s the baseline 
. I’d say that support itself is missing (probably as an oversight; I don’t think there are any implementation blockers here).
is there an issue for this on GitLab?
No I haven’t had a chance to follow-up on this. If you’d like to do the tests Ben mentioned and open an issue for this with those results recorded, that would be helpful.
