Q: How to produce a breakdown of how much it took to build each dependency of a target (recursively)?

### Page link:

https://bazel.build/advanced/performance/build-performance-metrics#execution-graph-log

### Problem description (include actual vs expected text, if applicable):

I'd like to be able to analyze build performance in terms of cumulative CPU time spent building all targets that are dependencies of the target I'm building. How can I do this?

### Where do you see this issue? (include link to specific section of the page, if applicable)

_No response_

### Any other information you'd like to share?

_No response_

Read the linked Build Performance Metrics page, especially the execution graph log section, and determine whether it explains recursive dependency CPU-time aggregation. Done means documenting a clear procedure or identifying the missing explanation needed to answer the question.
