I have a project I build using cmake. To build this project, I need to define several options like -DPRODUCT=amd64 -DXML_DIR=/opt/xml_database Normally, I either pass these as -D or configure them in IDEs like qtcreator and vscode. How would I define them in package cmake-ide? I feel like I need to add these to .dir-local.el but could not find an example.

Edit: I am trying to edit the variable given in the answer below and it has a type of string. I checked List Variables documentation but can't seem to make it work. In my dir_local.el

((nil . ((cmake-ide-cmake-args . 
            ("-DSOME_CMAKE1=foo_bar1" "-DSOME_CMAKE2=foo_bar2")
        ))
))

but this gives me errors related to type of the variable.cmake-ide-cmake-args has type of list of strings. So, how can I edit that variable? I also tried

((nil . ((cmake-ide-cmake-args . 
            (list "-DSOME_CMAKE1=foo_bar1" "-DSOME_CMAKE2=foo_bar2")
        ))
))

((nil . ((cmake-ide-cmake-args . 
            `("-DSOME_CMAKE1=foo_bar1" "-DSOME_CMAKE2=foo_bar2")
        ))
))
  • Note that it's .dir-locals.el and not .dir-local.el or dir_local.el. – nega Jul 16 at 20:59

Skimming the source of cmake-ide reveals

(defcustom cmake-ide-cmake-opts
  "-DCMAKE_BUILD_TYPE=Release"
  "The options passed to cmake when calling it.  DEPRECATED, use `cmake-ide-cmake-args' instead."
  :group 'cmake-ide
  :safe #'stringp)

(defcustom cmake-ide-cmake-args
  nil
  "The options passed to cmake when calling it."
  :group 'cmake-ide
  :type '(repeat string))

So, set cmake-ide-cmake-args via customize, a setq, as a file variable or a directory local variable.

cmake-ide-cmake-args should be a list of strings. This isn't clear in its docstring, and is currently an open issue.

So, if you want to set it via a .dir-locals.el you would do something like:

;;; Directory Local Variables
;;; For more information see (info "(emacs) Directory Variables")

((nil . ((cmake-ide-build-dir . "/Users/nega/build/foo")
         (cmake-ide-project-dir . "/Users/nega/src/foo")
         (cmake-ide-cmake-args  . ("-DCMAKE_BUILD_TYPE=Debug" "-DCMAKE_FOO=BAR")))))

Setting it via a setq would look like

(setq cmake-ide-cmake-args '("-DCMAKE_BUILD_TYPE=Release"))
  • Can you show me how to edit this variable of type '(repeat string)? I edited the question with further info. – meguli Jul 16 at 8:43
