[clangd-dev] Clangd on windows+vscode

[Ilya Biryukov via clangd-dev]

We don't really have alternatives to compile_commands.json that support
automatic indexing. You could use 'compile_flags.txt', but the
auto-indexing won't know which files it should feed into.

- What build system do you use and how did you generate the
compile_commands.json file?
- You mentioned ccls could index your project, did it work out of the box?
If it required user configuration, what was it?

Clangd relies on clang's code to parse command line, which is *mostly*
compatible
with GCC, but I'm not sure how it handles custom GCC toolchains (and
whether it handles those at all).
In general, if you manage to set up your build so that it uses clang and
generate compile_commands.json from that configuration - it should work
just fine.
