[Qbs] Unwanted linkage of non-cpp product by MSVC

[Павел Лысенко]

Hello

I have a project with some cpp products.
Also the project includes a non-cpp product.
Non-cpp product depends on my custom module that creates a custom deployment package.
Module can process both cpp and non-cpp products (so it have application input artifact). Also module use path to qt binaries from Qt.core module (so it have dependency on Qt.core module)

If I configure the project by QtCreator to use MinGW, all works fine, but if I use MSVC2017 (64 bit), it tries to link non-cpp product and fails with unresolved symbol mainCRTStartup.
Here is the short snippet that fails to build:

Project {
    Product{
        Depends{name:"Qt.core"}
        files:"main.txt"
        type:"test_output"
        Rule{
            inputs:["some_input_tag","application"]
            Artifact{
                filePath:"main.txt.output"
                fileTags:["test_output"]
            }
            prepare:{
                var cmd=new JavaScriptCommand();
                return [cmd];
            }
        }
    }
}

It looks like Qt.core have a dependency on cpp module, it tries to create an application artifact from 0 source files and fails on that. Is that a known issue?
Regards
Pavel
