When is `LLDBConfig.cmake` used? I'm trying to understand when the `LIBCXX_ENABLE_SHARED=OFF` setting will come into play. Will it influence whether `libc++.dylib` is built in the monorepo whenever you also happen to build LLDB?
Comment at: lldb/cmake/modules/LLDBConfig.cmake:79
+ # if not enabled explicitly in builds from the monorepo.
+ if("libcxx" IN_LIST LLVM_ENABLE_PROJECTS AND NOT "libcxxabi" IN_LIST LLVM_ENABLE_PROJECTS)
+ set(LIBCXX_ENABLE_SHARED OFF CACHE BOOL "" FORCE)
So when both `libcxxabi` and `libcxx` are enabled, we will build `libc++.dylib` and `libc++.a`? Why not always disable it?
