Yes, absolutely.

I think there's a misunderstanding of what <subproject> is. It's a way=20
to build another set of targets that don't depend on targets in the=20
"parent" makefile (and a makefile of its own is created for=20
subproject). If you have an executable target that depends on a=20
library, then you should do something like this instead:

<lib id=3D"guidelib">
=2E...
</lib>

<exe id=3D"demo">
   <library>guidelib</library>
</exe>

The <library> tag makes guidelib a dependency of demo and ensures=20
correct linker settings.

Because you can't make a .dsw depency of another .dsw file and at the=20
time demo.dsw is generated, nothing is known about the content of=20
guidelib bakefile so it can't infer what dsp files there will be (so=20
that it could make all of them dependencies).

That's because there's no way (that I know) to save & restore current=20
directory in Borland's make. Maybe it's possible to workaround it=20
somehow, but I don't (yet) know how. The underlying cause is that=20
<subproject> is meant to be used with subdirectories, not=20
subdirectories of parent directories.
