In our meson scripts, we use configure_file(copy:true) to copy files from srcdir into builddir. However, as of meson-0.64.0, this is deprecated [1] in favor of using:

fs = import('fs') fs.copyfile(in, out)

Except, the submodule's new method wasn't introduced until 0.64.0. And since we can't bump the minimal meson version we require, we have to work with both: new and old versions.

Now, the fun part: fs.copyfile() is not a drop in replacement as it returns different type (a custom_target object). This is incompatible with places where we store the configure_file() retval in a variable to process it further.

While we could just replace 'copy:true' with a dummy 'configuration:...' (say 'configuration: configmake_conf') we

Actually, it would be even more clear that it is a dummy configuration if you used a dict instead of cfg_data. Meson allows this in configure_file() according to the docs: https://mesonbuild.com/Reference-manual_functions.html#configure_file

can't do that for binary files (like src/fonts/ or src/images/).

Therefore, places where we are not interested in the retval can be switched to fs.copyfile() and places where we are interested in the retval will just use a dummy 'configuration:'.

Except, src/network/meson.build. In here we not just copy the file but also specify alternative install dir and that's not something that fs.copyfile() can handle. Yet, using 'copy: true' is viewed wrong [2].
