[Qt-creator] Building a plugin on windows.

[Hugo Parente Lima]

Hi,

I'm a newbie about Windows but started to try to compile my QtC plugin 
under a Windows7 VM, I did the following steps:

1. Installed Qt + QtCreator (checked some MSVC runtime libraries too).
2. Cloned QtC and checked it to version 3.6.1.
3. Cloned my plugin[1] and checked it to branch qtc-3.6.
4. Did open the plugin project (.pro) into QtCreator.
5. Added QTC_SOURCE and QTC_BUILD variables to the qmake call.

Triggered the compilation and everything went fine until... link time, 
on Windows my plugin is looking for some dependencies unknow to me, 
here the linker output.

Ugly as an usual linker output, but these 3 plugins were not in Windows 
QtC install, however these plugins exists when I compile QtC on Linux. 
should I add some Windows specific flag in the .pro?

Thanks in advance.
