Identifier for win64 configuration in Qmake

Question

Is there a \"win64\" identifier in Qmake project files? Qt Qmake advanced documentation does not mention other than unix / macx / win32.

So far I\'ve tried using:

Answer 1

I've figured out one way to do it.

Qt allows you to pass arbitrary config parameters which you can use to separate the targets.

By having a conditional config in your project file:

CONFIG(myX64, myX64|myX32) {
    LIBPATH += C:\Coding\MSSDK60A\Lib\x64
} else {
    LIBPATH += C:\Coding\MSSDK60A\Lib
}

and passing that custom config to qmake with

qmake CONFIG+=myX64

you get the wanted result.
