Sorry for the false assertion. I assumed, wrongly, that add_custom_command had same behaviour as execute_process for which the doc clearly explains that System API are used (no shell used). So, adding some precisions on how add_custom_command (and add_custom_target I presume) launch specified commands should be a nice enhancement.
