that only depends on

However, generate.py just blindly captures everything in build/lib/clang/**:

which causes two types of issues:

• We distribute more than we necessarily need/want
• Flaky build errors. The way output files are created is often such that in-progress writes happen to a temporary file that is later renamed once all the writes finish. If that file is created by a project/runtime we don't depend on, then resource.cpp might capture that temp file that won't be available by the time resource.cpp is being built, failing at the corresponding #embed directive.
