Terrible…

Can we pass them as an argument to ‘meson’ somehow instead of defining a
global variable?

(For example Autoconf-generated configure scripts can read variable
definitions passed as arguments:

  ./configure LDFLAGS=foo

That way we don’t have to define the variable globally, which could have
unintended effects.)

If not, that’s fine.

Thanks,
Ludo’.
