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 do it like this

win32 {

    ## Windows common build here

    !contains(QMAKE_TARGET.arch, x86_64) {
        message("x86 build")

        ## Windows x86 (32bit) specific build here

    } else {
        message("x86_64 build")

        ## Windows x64 (64bit) specific build here

    }
}
