ccls 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).

Customization options are passed to ccls at initialization time via init_options, a list of available options can be found [here](https://github.com/MaskRay/ccls/wiki/Customization#initialization-options). For example:

```lua
local lspconfig = require'lspconfig'
lspconfig.ccls.setup {
  init_options = {
    compilationDatabaseDirectory = "build";
    index = {
      threads = 0;
    };
    clang = {
      excludeArgs = { "-frounding-math"} ;
    };
  }
}

```
