Switching between clangd instances

Hello,

I have a project and it have very heavy and big cmake structure. We use presets and cmake toolchain files and ninja multi-config under linux too. On linux I have a problem with clangd.

At the top I can switch between two clangd instances as you can see on the picture

My project specific clangd doesn't work. It cannot parse glm's inlined headers. The global clangd works well, but by default the project specific clangd is used.

If I check the cmd line of the clangds from shell I can see that both are started with the same parameters except that one of them has --compile-commands-dir parameter (that points to an existing directory, where there is a creator generated compile_commands.json).

Unfortunately I cannot identify which process belongs to which clangd setup.

Could you tell me a way how can I make the global clangd the default clangd instance on the whole project?

Thanks:
