How to create a quick plugin with a dot "." in the "URI"

[Sauntor]

After you create a Qt Quick 2 Extension plugin in qtcreator with cmake as the build system (let the project name to be MyDemo and check the Create example project checkbox ),
Then, you will get something like this in the CMakeLists.txt:

qt_add_library(MyDemo STATIC)
qt_add_qml_module(MyDemo
    URI MyDemo
    VERSION 1.0
    QML_FILES MyItemControls.qml
    SOURCES myitem.cpp myitem.h
)

After that, if you change the URI MyDemo to URI My.Demo, the exmaple subproject can not be compiled successfully.

no matter changing the qmldir file in the project root or not, the example project can not be compiled

So, how to define a Quick extension plugin with an URI which contains a dot like My.Module.UI?

@Sauntor You use the dot notation to reflect your project structure. If you have the following project structure: MyDemo/InnerMyDemo. In the CMakeLists.txt inside you InnerMyDemo dir you can have:

add_library(InnerMyDemoLib)
qt_add_qml_module(InnerMyDemoLib
    URI MyDemo.InnerMyDemoLib
     ....
)

Look at: https://doc.qt.io/qt-6/cmake-build-reusable-qml-module.html, https://doc.qt.io/qt-6/qtqml-writing-a-module.html

Note: If you don't want to reflect your project structure there's some CMake variable to define your custom layout. Look at: https://doc.qt.io/qt-6/qtqml-writing-a-module.html#custom-directory-layouts

@Anumas Thanks, I find out the really problem I got before, URI will composed with QT_QML_OUTPUT_DIRECTORY and the OUPUT_DIRECTORY parameter of qt_add_qml_module() to making some directories or target filename while building, and that cause conflicts
