  - You can use `cmake -G Ninja ..` to use Ninja build system instead of the native one. (`sudo apt install ninja-build`)

 There is a GUI tool that can help for writing MMVII command : vMMVII
 
 It will be automatically compiled with MMVII if development package Qt5 (or Qt6) is installed (Ubuntu 22.04: `sudo apt install qtbase5-dev`)

 - This tool is beta: some MMVII parameters may be misinterpreted or not have the good File Dialog helper.
