Convert VS2010 project from Win32 to Qt5

[Henrich]

Hi!
First, it's important that if you are building for 32bit, you also have also 32bit version Qt and also it should have the same compilator MSVC not mingw.

The keyword should be <keyword>Qt4VSv1.0</keyword> that is correct, I am using VS2012 and Qt5.2.1 and it is working.

Maybe you could try newer version of Qt_vs_addin, try version 1.2.3, for example 1.2.4 is not working with VS2012, don't know why, and I am not the only one with this problem.

Thanks for your reply. Yes, I think it must be something with Qt Add-in 1.2.2. I was going a little bit crazy yesterday, since (as always happens when you run into something like this) I'm under a pretty tight deadline. I finally made a copy of my whole solution folder, and then reverted the original back to a buildable copy from SVN (thanks SVN!!), and then I diffed the .vcxproj in the reverted folder to the one that wasn't working. I tried manually changing stuff in the one that wasn't working and compiling, and what I found was that the 1.2.2 add-in had put a $(INHERIT) variable into some places. In one of those places it had the form: <some_previous>\;$(INHERIT)\;<some_next> ... So somehow it messed up. I removed the backslashes and it just compiled like ever before. So though I don't have time to be sure right now, I'm thinking you are probably correct about the add-in version. Thanks again.
