This is an interesting question. The thing about MSVC is that it may or
may not create a .lib file, depending on whether symbols were exported
or not. Now, does it make sense to depend on a DynamicLibrary product
without using "cpp.link: false" if that library does not export any
symbols? Probably not, but since this continues to come as a surprise
to users (e.g. https://bugreports.qt.io/browse/QBS-1291), I suppose we should provide a better error message (i.e. don't wait for the linker to fail).
I'll take a look.
