Weird thing

The codebase is modified, but only 2 source files of clangd sub-project. No CMake-related file was modified. It could be configured successfully 2 weeks ago, but now it is generating errors. I don't know why and feel confused.

More info

This codebase is patched with those mentioned in link, based on branch release-18.x. Specifically, hover-doxygen-trunk.patch. link for the patch file.
I don't think this issue is related with the patches, since they worked perfectly well 2 weeks ago.

Problem solved. It's caused by an external cmake toolchain (in my case, vcpkg). In the documentation I suggest adding a warning to remind people to disable the toolchain when configuring llvm.

i'm facing this issue today, can you expand on what your fix was?
