coding style: components

[Yury G. Kudryashov]

Hi!

Which libraries should be included in XXX_LIBRARIES if different users need 
different subset of the libraries provided by XXX?

E.g., gstreamer installs libgstreamer, libgstbase, libgstnet etc.

I can add COMPONENTS and set XXX_LIBRARIES to the list of requested 
libraries but I don't know how to make it work if find_package(GStreamer) is 
called twice in different subdirectories with different COMPONENTS 
arguments.

What do you recommend?

P.S.: Current FindGStreamer hardcodes the following:
* GSTREAMER_FOUND is TRUE if libgstreamer, libgstbase and libgstinterface 
are found;
* GSTREAMER_LIBRARIES contains ONLY libgstreamer.
