Because development files should depend upon the libraries they
provide the headers for, not the other way around. It's the basics of
library packaging.

And then again, wrong. Making an IDE show the header a compiler is
**NOT** using it's plain **WRONG**. I already expressed that in the
bug upstream and in Qt Creator's bug. Note that I did even stress the
question in upstream's bug just to show that nobody could say
otherwise. Neither Marko nor Thiago denied that.

So if you want a fix make clang understand other compiler's headers,
or provide a better code parser.

Regards, Lisandro.
