Platform specifications are currently not supported for dependencies due 
to the way the dependency resolver works. However, it is possible to use 
platform specific configurations for this purpose:

name "dedcpu"
authors "Luis Panadero Guardeño"
targetType "none"
license "BSD 3-clause"
description "DCPU-16 tools"

subPackage {
    name "lem1802"
    description "Visual LEM1802 font editor"
    targetType "executable"
    targetName "lem1802"
    excludedSourceFiles "src/bconv.d"
    excludedSourceFiles "src/ddis.d"
    libs "gtkd" platform="windows"

    configuration "nogtk" {
       platforms "windows"
    }

    configuration "gtk" {
       platforms "posix"
       dependency "gtk-d:gtkd" version="~>3.2.0"
    }
}
