Can you please run a cargo clean and then do a cargo build -vv again and attach the output?

The log has a lot of Fresh <cratename> so it doesn't look like a clean build

The log has a lot of Fresh <cratename> so it doesn't look like a clean build when i create new project and add opencv crate,show same error log

[twistedfall]

This log doesn't contain the debug output that the build script of the opencv crate produces during its build. Maybe you have some kind of target directory sharing or caching?

Perhaps you could delete the target/ directory, re-run cargo build -vv and post the logs here?
