That's OK.  I can certainly relate :-) Though in many platforms I know
setting up this clangd language server is just about installing the
"clang" package available in many distribution.

On a tangent, it'd be great if Emacs could come with at least one
ready-to-use LSP server for debugging things like these.  Maybe an Elisp
server, although LSP servers for Elisp are kind of silly IMO, since LSP
is very inferior to Emacs's own facilities for debugging Elisp.  So a C
LSP server would be the next natural choice.

OK thanks, I'll have a look when there's a bit more space on my plate.
