\include{Glossary} does not work

Question

I am writing the final version of my PhD thesis. Everything works fine except that the Glossary external file I created is completely ignored by the program. I am using Texstudio to compile it. The problem is that the Glossary is not even printed in the Index (Table of contents), and so it is not present in the pdf file. I attach here both the Glossary and main file. Any help is completely appreciated!
