title: Can Meson read the contents of a file
body: <p>Is it possible for Meson to read the contents of a file into an array or a string?  From <a href="https://github.com/mesonbuild/meson/blob/master/docs/markdown/Syntax.md" rel="noreferrer">here</a> a string can be split into an array, and an array can be looped over with <code>foreach</code>, but I haven't been able to find a way to get the data from the file to start with.</p>
