Another relicensing request for build related files. #73

Hello again!
Followong up on #51

There is one last file I would ask you to look into relicensing the meson.build files.

The commit history suggests the meson.build and meason build related options files were relicensed from a code centric license to a content centric game. They probably need to be changed under the same grounds.

The meson* files are the last sticking point in the Fedora package review concerning the license friction around CC being used for code versus content.

I'm trying to avoid kicking off a formal legal review from a lawyer, so if you agree that meson files are code related and not content, and cane make the licensing change similar to the the changes you made in pull request #51 that would be great.
