    windows: Use the 'WIX' environment variable to find heat.exe
    
    On x64 systems, WIX installs itself in "Program Files (x86)" instead of
    "Program Files," so the build-installer script cannot find `heat.exe`
    in these cases. Using the `WIX` environment variable to locate the
    binary solves this problem.
