CMake deprecation error < 3.5

[D3vil0p3r]

I'm using NixOS with Neovim. Installing telescope-fzf-native.nvim by the following telescope.lua file:

local status_ok, telescope = pcall(require, "telescope")
if not status_ok then
  return
end

local actions = require "telescope.actions"

vim.api.nvim_set_keymap('v', '<C-g>', 'y<ESC>:Telescope live_grep default_text=<c-r>0<CR>',{ noremap = true, silent = true })

telescope.setup {
  pickers = {
    find_files = {
      previewer = false,
      hidden = true
    },
    colorscheme = {
      enable_preview = true,
    },
  },
  extensions_list = { "themes", "terms" },
  defaults = {
    prompt_prefix = " ",
    selection_caret = " ",
    path_display = { "smart" },
    file_ignore_patterns = { "node_modules" },
    mappings = {
      i = {
        ["<C-j>"] = actions.move_selection_next,
        ["<C-k>"] = actions.move_selection_previous,
        ["<C-c>"] = actions.close,
        ["<C-n>"] = actions.cycle_history_next,
        ["<C-p>"] = actions.cycle_history_prev,
        ["<C-q>"] = actions.send_to_qflist + actions.open_qflist,
        ["<CR>"] = actions.select_default,
      },
      n = {
        ["j"] = actions.move_selection_next,
        ["k"] = actions.move_selection_previous,
        ["<C-q>"] = actions.send_to_qflist + actions.open_qflist,
        ["<C-x>"] = actions.select_horizontal,
        ["<C-v>"] = actions.select_vertical,
      },
    },
  },
}

-- Enable telescope fzf native, if installed
pcall(telescope.load_extension, 'fzf')

and when I place telescope.lua among the plugins of Neovim, when I run nvim for the first time, at compilation time of this plugin I get

In plugins.lua it is dealt with:

  {
    'nvim-telescope/telescope-fzf-native.nvim',
    build =
    'cmake -S. -Bbuild -DCMAKE_BUILD_TYPE=Release && cmake --build build --config Release && cmake --install build --prefix build'
  },
  {
    "nvim-telescope/telescope.nvim",
    dependencies = {
      'nvim-telescope/telescope-fzf-native.nvim', -- file icons on nvim-tree
    },
  },

Why I get this deprecation error despite I'm using CMake 3.27? The problem is in CMakeLists.txt at:

cmake_minimum_required(VERSION 3.2)

?

[Conni2461]

we could bump the minimum_required cmake version to idk 3.9

[D3vil0p3r]

we could bump the minimum_required cmake version to idk 3.9

We can try to see if it fixes this issue.

[ditsuke]

The real issue is in the build command advertised by the plugin. The final install step fails at

file(INSTALL DESTINATION "/home/x/.local/share/nvim/lazy/telescope-fzf-native.nvim/build" TYPE SHARED_LIBRARY FILES "/home/x/.local/share/nvim/lazy/telescope-fzf-native.nvim/build/libfzf.so")

At first look this install step is entirely redundant. On second look its dangerous because it is undefined behavior which new versions of cmake seem to have affected. So PSA for people coming here:

-          cmake --build build --config Release && \
-          cmake --install build --prefix build",
+          cmake --build build --config Release",

Alternatively use build = 'make'

I get the same issue, also on NixOS. I tried changing the build command in my lua config to both 'make' and 'cmake -S. -Bbuild -DCMAKE_BUILD_TYPE=Release && cmake --build build --config Release' and it did not seem to change anything; I still get the issue.

I did, however, find a workaround: just go to your shell and manually run make:

cd [nvim data dir]/lazy/telescope-fzf-native.nvim
make
