Autore: **//Fabio Di Matteo//** \\ Ultima revisione:  **//  26/04/2023  - 13:00   //**  // //


Avviare lo script come segue:
<file>./auto-gtkmm <nome cartella mio progetto></file>
viene creato lo scheletro dell'applicazione.


<file>meson setup build </file>
viene configurato il progetto nella cartella "build"


<file>
cd build  
ninja
</file>
viene compilato il progetto

**auto-gtkmm**

<code bash>
#!/bin/bash
