**NOTE:** Clang >= 9 is recommended! See [this issue for more](https://github.com/neovim/nvim-lsp/issues/23).
clangd relies on a [JSON compilation database](https://clang.llvm.org/docs/JSONCompilationDatabase.html) specified
as compile_commands.json or, for simpler projects, a compile_flags.txt.
For details on how to automatically generate one using CMake look [here](https://cmake.org/cmake/help/latest/variable/CMAKE_EXPORT_COMPILE_COMMANDS.html).
