Right compiler for Qt and external libraries

Hi everyone, I am new to Qt and I have this huge problem that I have to solve. After spending days in trying to fix it I finally decide to ask in this forum. So I have this project to do and I need to work with Qt and two known libraries (Opencv and PCL, point cloud library). So I installed the last version of Qt (5.3.2) w/ MinGW32-etc and then I decided to download and try one library at a time, instead of all the libraries together. So I started with opencv, that I built with qt support and everything went fine (my qt+opencv test programs). Then I downloaded PCL and I discovered that (under windows) it needs msvc 2010. So I downloaded the microsoft sdk 7.1, hoping that in this way I was able to select the msvc 2010 compiler in the Qt build options: it doesn’t work because there is no qt version able to compile for the selected compiler. So does this mean that I have to download the msvc 2010 version of Qt? Will the opencv libraries compiled with mingw still work? Now that I have installed the Microsoft SDK 7.1, do I have the right compiler (msvc2010) for using PCL with Qt? Thank you very much for you answers.
