[ptxdist] Handling build time only dependencies

Hello,

I'm a little stuck with a problem I consider a maybe common one. I
have an ordinary C library. For some projects I compile and link
against it the usual way, so in my applications .in rule I just do
'SELECT LIBFOO' and the library package will be copied to the target
including .so file, loading at runtime etc.

Now for another BSP I have another application where I only need to
include some header files of this library, but do not call any API
functions and do not link against it. So I only need the library at
build time, no library package has to be copied to the target later
and the library doesn't need to be loaded at runtime.

Can I express this somehow in ptxdist and how?

(This is just to save space on the target, I know I could let copy the
lib to the target, where it won't be loaded then, which is the way
it's done currently.)

"select LIBFOO if BUILDTIME"
