Opencv precompiled mingw binaries with qt?

Hello there. I recently discovered that qt had good GUI systems at worked well with opencv. Naturally I rushed to try it. I discovered that there were even precompiled libraries and binaries for mingw. Now, considering the fact that I have never used qt before, I just did what the last parts of the tutorials said (the parts after cmaking the libraries and building them). Unfortunately, the qt environment cannot find the library files. It says it cannot find the libraries hat I am including and that they do not exist. ( I have had this problem with visual studio too but I resolved it with proper path declaration)

the tutorial I mainly used was this one.

As far as I understood I had only to include the bin folder in the system path and then add the libs and include paths. I obviously replaced their directories with their equivalents in my system, and I replaced 231 in each include with 245. Now, is there anything that I missed? I it absolutely imperative that I compile from source to make it work? I would appreciate any light anyone can shed on the matter.
