Forum is a little hard to search so sorry if this has been asked before

I am trying to create a .pro file that can used used on multiple platforms to build a library (MyLib.so,MyLib.dll,...). Seems fairly easy with qmake and it all works, except that the name of the library has a prefix 'lib' when built on a *nix system (libMyLib.so). And this might be okay except for the fact that I am using QLibrary to load the library and trying to use a common name: Qlibrary mylib("MyLib"). While QLibrary does try different extensions (.so,.dll), it does not try to add a 'lib' prefix. So is there a way to have qmake build a lib with a name that I specifically want?
