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:
win32:message("using win32")
win64:message("using win64")
amd64:message("using amd64")
The result is always "using win32".
Must I use a separate project-file for x32 and x64 projects, so they would compile against correct libraries? Is there any other way to identify between 32-bit and 64-bit environments?
