of the build directory. It is used just the same as `command-output`:
.. run-command:: <command>
:cwd: /directory
The only difference to `command-output` is that the current working directory
defaults to the current build folder, and the directory (optionally) given
to the `cwd` option allows for the following placeholders:
- `<build>`: current build folder
The path of the build folder needs to be configured in the `runcmd_build` option.
