Using cmake grammar from https://github.com/uyha/tree-sitter-cmake

Reproduction:
1. emacs -q
2. C-x C-f test.cmake
3. M-x cmake-ts-mode
4. Insert the following text:
if(TRUE)
message("indent")
endif()
5. Move the point to the beginning of the second line.
6. TAB
7. Notice that no indentation is performed.

treesit-simple-indent-rules local value:
((cmake
  ((node-is ")")
   parent-bol 0)
  ((node-is "else_command")
   parent-bol 0)
  ((node-is "elseif_command")
   parent-bol 0)
  ((node-is "endforeach_command")
   parent-bol 0)
  ((node-is "endfunction_command")
   parent-bol 0)
  ((node-is "endif_command")
   parent-bol 0)
  ((parent-is "foreach_loop")
   parent-bol cmake-ts-mode-indent-offset)
  ((parent-is "function_def")
   parent-bol cmake-ts-mode-indent-offset)
  ((parent-is "if_condition")
   parent-bol cmake-ts-mode-indent-offset)
  ((parent-is "normal_command")
   parent-bol cmake-ts-mode-indent-offset)))

treesit-explore-mode shows:
(if_condition
 (if_command (if) (
  (argument_list
   (argument (unquoted_argument)))
  ))
 (body
  (normal_command (identifier) (
   (argument_list
    (argument
     (quoted_argument " (quoted_element) ")))
   )))
 (endif_command (endif) ( )))
