I take it back.
It is not hard coded. It is just matching qt win32-msvc2010,
win32-msvc2012 with the correct CMake generator:
win32-g++*:CMAKE_GENERATOR = -G \"MinGW Makefiles\"
41 win32:equals(QT_ARCH, x86_64) {
42 win32-msvc2010:CMAKE_GENERATOR = -G \"Visual Studio
10 Win64\"
43 win32-msvc2012:CMAKE_GENERATOR = -G \"Visual Studio
11 Win64\"
44 }
41 45
What about VS 9, seems to be missing?
What are all the possible values of win32-??

I suppose the arch problem occurred because Qt was built in 64bit mode, and
that has nothing to do with devenv.
Yes, that is correct, you have to figure out if Qt is 64 first, and then
configure CMake.
I can put a variable in the Qt5Core config file containing the arch. Better
yet, I can put it in a INTERFACE_TARGET_ARCH target property and have cmake
ensure that all targets are compatible.
Such a TARGET_ARCH should be a built-in property in CMake, and CMake should
also check it for each target against the generator. That would at least
give a sensible error message about what the problem is at cmake-time.
This might also be generally useful for storing an arch triple on linux
systems? Can 32 and 64 bit libs be mixed there?
I don't think they can be mixed anywhere.
This isn't for 2.8.11 obviously.
Sure.
