I'm a bit confused about this question. Can I use Qt compiled with Visual Studio 2013 in my Visual Studio 2010 projects?
I'm using other libs that are build with different compiler versions and I have no problem so I think that this is ok.
My confusion starts when downloading Qt 5.4.1 as there are versions for VS 2013, VS 2012 and 2010.
Maybe I need the right compiled version if I want to compile MySQL module, but its ok to use any version if I only want to use the libs to compile my projects?
