+** CMake configuration
+=cmake-ide= plugin works out of the box, but there are few 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 sample configuration. This configuration force =cmake-ide= to use local
+directory and pass that directory to =helm-make=. Such config allows to build your
+project with ~SPC c c~ shortcat.
