Tkanks  Now the outputs are going to be a mix of file types - one or 
more source files and an object type.

It may also be necessary to try to convince ninja to use a generated 
dependency file.

I see that we specify objects specifically:

|exe = executable('myexe', 'source.cpp', objects : 'third_party_object.o')|

and the a generator output list can be gathered and used like this:

gen_src  =  gen.process('input1.idl',  'input2.idl')
executable('program',  'main.c',  gen_src)

If gen_src is a mix of objects and sources, how can I pass it to 
'executable'?  In this case I'd have an obj file as a result of cvtres, 
and the generated COM server implementation files.

Will the program I define for the generator be invoked by ninja with 
dependency generator options determined by the primary C++ compiler 
type?  Can I influence it?
