Building 64 bit visual studio projects .sln

[drescherjm]

I know I can have qmake generate Makefiles and use that to build 64 bit executables by building these inside a "Visual Studio 2008 x64 Command Prompt".

However if I have it generate visual studio projects it builds as win32 bit instead of 64 bit even though I ran the 64 bit qmake executable in a the same x64 command prompt.

Apparently, this is a limitation:

But you can open the 32-bit solution file, add a 64-bit config, and it will work.
