[PATCH] D137534: [C++20] [Modules] [ClangScanDeps] Allow clang-scan-deps to without specified compilation database in P1689 (3/3)

[Ben Boeckel via Phabricator via cfe-commits]

ben.boeckel added a comment.

So a few things I see when trying to put this into CMake:

- P1689 <https://reviews.llvm.org/P1689> output is only to `stdout`?
- Is there a way to get `-MF` output for the files read during scanning? This is useful to know that "header X changed, scanning may have changed, so please rerun scanning".

Other than that, I have success with CMake's test suite with this patchset as well as the patchset of D137059 <https://reviews.llvm.org/D137059>.
