I thought, as the normal GNU build system is used here, I'll use that.
But reading the documentation again, I've found out, that what you
mentioned is a good idea. I'll change this.

I carefully checked all the library source dependencies and so on. I
think all these propagated inputs are needed.

If that is necessary, I'll add these comments, but I think it's not too
difficult to look into the .pc files. Some of the packages have
comments, but the most don't.

I also saw that, but I thought, if the .pc file isn't referring to
something, it doesn't make sense to add it, because pkg-config
won't add the necessary compiler flags and libraries, so that gcc isn't
finding it.

But actually I don't really know. I'll recheck all the .pc files and
headers (not too much).

In general I think you should wait until I've ready the rest of MATE
(caja, mate-control-center and stuff like documentation or wallpapers),
so that it can be tested by me first. The patches I've sent were more
for corrections and review.

So thanks for the hints!
