[QBS] Do not called custom Rule from custom Module

[kuzulis]

Hi all.

I need for my project use the Windows software tracing feature:

http://msdn.microsoft.com/en-us/library/windows/hardware/ff556204(v=vs.85).aspx

For this purpose need to call the "tracewpp.exe" utility with passing a list of project's source files (.cpp) to them,
and then, the "tracewpp.exe" utility will create a set of the (.tmh) header files.

So, I trying to create a custom QBS module "modules/wpp/WppModule.qbs":

@
import qbs 1.0

Module {
property string wppTraceModuleHeadersDir: ".tmh/" + product.name
condition: qbs.hostOS.contains('windows') && qbs.targetOS.contains('windows') && qbs.toolchain.contains('msvc')
cpp.includePaths: product.buildDirectory + '/' + wppTraceModuleHeadersDir

Rule {
    inputs: ["cpp"]
    Artifact {
        fileName: ModUtils.moduleProperty(product, "wppTraceModuleHeadersDir")
                  + '/' + input.completeBaseName + ".tmh"
        fileTags: ["tmh"]
    }

    prepare: {
        var wpp_exe = "c:/Program Files/Windows Kits/8.0/bin/x86/tracewpp.exe";
        var wpp_cfg_dir = "c:/Program Files/Windows Kits/8.0/bin/WppConfig/Rev1";
        var args = input.fileName;
        args.push("-cfgdir:" + wpp_cfg_dir);
        args.push("-odir:" + ModUtils.moduleProperty(product, "wppTraceModuleHeadersDir"));
        var cmd = new Command(wpp_exe, args);
        cmd.description = "generating WPP " + output.fileName + " file";
        cmd.highlight = "filegen";
        return cmd;
    }
}

}
@

and then in my project file I to do:

@
import qbs.base 1.0

DynamicLibrary {
name: "foo"
...
...
Depends { name: "wpp" }
...
...
files: [
"bar.cpp",
]
}
@

But in my case this does not work, the command do not called.. What I to do wrong?

Best regards,
