I think the recommended way is to add suffix rules to produce the built
sources, not edit the Makefile.ins.

I'm not sure the production of built sources (or generation from meta
files as you put it) and wildcarding are directly related.

My preferred route with built sources (esp. from CORBA IDL) is to add
suffix rules to generate them and list the generated sources in the

I suppose automake could be enhanced so that it automatically knew which
files are BUILT_SOURCES by looking back through the suffix rules. Then
the small overhead of listing them twice would be removed.

IMHO wildcarding is a separate issue, independent of whether sources are
built or normal.
