+their use is discouraged because of the many caveats in using them. Instead it
+is recomended to use <code>-D${lang}_args</code> and
+<code>-D${lang}_link_args</code> instead. Among the benefits of these options
+is that they are guaranteed to persist across rebuilds and reconfigurations.

+Meson does not allow changing compiler in a configured builddir, you will need
+to create a new build dir for a different compiler.
