Copy compile_commands.json to the root of your project

cp /home/vector/applications/qt/untitled/build/Desktop-Debug/compile_commands.json /home/vector/applications/qt/untitled

Setup up clangd

local capabilities = require('blink.cmp').get_lsp_capabilities()
require 'lspconfig'.clangd.setup {
  capabilities = capabilities,
}
