building a static lib with links to other static libs

Hi everybody,

I've build a library that add s some QT functionality (f.e. signal / slot) to the PVM communication and called it "libqpvmlib".
Now I tried to link that lib static. So my part of the common lib needs the original static PVM libs.
Unfortunately I didn't succeed to edit the .pro in that way that libpvm3.a will be linked to my "libqpvmlib.a".

Can anyone help?

Regards
