How do I set up Qt paths in Visual Studio 2010?

Question

I just downloaded and installed the latest versions of the Qt SDK, Qt Creator, and the Qt add-in for Visual Studio (I'm running VS 2010).

First, I tried creating a Qt project in VS2010. It came up with

Unable to find a Qt build!

To solve this problem specify a Qt build

So I go to the Qt -> Qt Options menu item in VS and click Add for the version.

Now, I have 2 qmake.exe files: one in C:\Qt\2010.05\qt\qmake and one in C:\Qt\2010.05\qt\bin

For some reason, if I select either one of these files, it comes up with the error message the this version of Qt was built with MingW. (I don't see why it makes a difference what compiled it, just so long as it's compiled?)

After spending some time trying to find a working qmake.exe for the VS add-in I gave up and tried to get the original Qt creator to work instead.

Qt creator is also not configured to run with itself (lol). When I select the path to either of my 2 qmake.exe files, it comes up with an error message when I try to compile a small program:

Could not find make command: make in the build environment

Error while building project untitled (target: Desktop)

When executing build step 'Make'

When I check the options in Qt creator, it says qmake is at version 4.7.0 and that

Qt version is not properly installed, please run make install

The VS2010 add-in is installed to my program files (x86) folder, but there are no qmake.exe files there.

I'm running Windows 7 x64.

I'm almost positive that you have to rebuild the Qt libraries in Visual Studio first before you can use them. That probably explains why you're getting the error message that a Qt build can't be found, and that the version of Qt you're using was built with MinGW.

I suggest reading this blog post for what looks to be a solid how-to guide on integrating Qt with VS.

This looks like an even simpler guide, although it's in PDF format: Qt Installation for Visual Studio
