arichardson added a comment.
In case anyone else runs into this: It appears this change somehow broke
incremental builds with `-DLLVM_ENABLE_RUNTIMES=libunwind` (even after deleting
CMakeCache.txt in the main build dir):
-- Using libunwind testing configuration:
/home/alexrichardson/cheri/upstream-llvm-project/libunwind/test/lit.site.cfg.in
CMake Error: File
/home/alexrichardson/cheri/upstream-llvm-project/libunwind/test/lit.site.cfg.in
does not exist.
CMake Error at

(configure_lit_site_cfg)
-- Configuring incomplete, errors occurred!
Fortunately this is quite easy to fix: `rm -rf <build_dir>/runtimes` and then
run `ninja` again.
I'm not sure if this would help (and I don't have a broken build dir anymore),
but it might be possible to avoid this problem by touching CMakeLists.txt in
llvm/runtimes?
