Description

This layer adds support CMake scripts.

Features:

• Support for CMake configure/build (with limited support for other build systems), automatic generation of compile_commands.json (compile flags), on-the-fly configuration of flycheck, company-clang and RTags (if installed) with cmake-ide.
• Run selected test using Helm interface via helm-ctest.

Install

Layer

To use this configuration layer, add it to your ~/.spacemacs. You will need to add cmake to the existing dotspacemacs-configuration-layers list in this file.

CMake-ide configuration

To enable CMake projects support set the layer variable cmake-enable-cmake-ide-support to t in the dotfile:

  (setq-default dotspacemacs-configuration-layers
    '((cmake :variables cmake-enable-cmake-ide-support t)))

cmake-ide plugin has several useful configuration options.

To configure project you need to create .dir-locals.el file. In case of using make as CMake backend you can use helm-make to select required build target.

Here is a sample configuration. This configuration forces cmake-ide to use the local directory and pass that directory to helm-make. Such config allows to build your project with SPC c c key binding.

Additionally it’s possible to configure helm-ctest in the same way via defining helm-ctest-dir. Trailing slash is required.

  ((nil .
        ((cmake-ide-project-dir . "~/Project")
         (cmake-ide-build-dir . "~/Project/build")
         (cmake-ide-cmake-opts . "-DCMAKE_BUILD_TYPE=Debug")
         (helm-make-build-dir . "build")
         (helm-make-arguments . "-j7")
         (helm-ctest-dir . "~/Project/build/")
         )))
