Can't import dynamic library as QML module

When running the attached project, I get:

qrc:/qml/main.qml:4:1: module "Flint" is not installed

The library's .dll is next to the binary in the install-root folder, so should be found by the QML engine, but because it's missing a qmldir, the engine can't find it. Qbs needs to generate a qmldir like CMake does (and probably also a plugins.qmltypes).

For example, QtQuick.Templates has these files generated for it:

Mitch@Mitch-Win10 MINGW64 /c/dev/qt-dev-debug/qtbase/qml/QtQuick/Templates
$ ls
plugins.qmltypes  qtquicktemplates2plugind.dll*          qtquicktemplates2plugind.exp  qtquicktemplates2plugind.lib
qmldir            qtquicktemplates2plugind.dll.manifest  qtquicktemplates2plugind.ilk  qtquicktemplates2plugind.pdb

I can work around it by referencing any symbol from the library in C++ in the app; e.g. including a header and instantiating some class.
