This is a stripped version of the project in which this happens:
# clear cache
rm -rf node_modules/.cache
# build lib (with CI flag enabled to force in-process-hash)
CI=true npx nx run-many -t build --projects=some-lib
# build app (with CI flag enabled to force in-process-hash)
CI=true npx nx run-many -t build --projects=some-appFirst output, as expected, builds lib
> NX Running target build for project some-lib:
