"QML module not found" but application runs

[ECEC]

I've created a module in a subdirectory as follows:

cmake_minimum_required(VERSION 3.16)

project(superapp VERSION 0.1 LANGUAGES CXX)

set(CMAKE_AUTOMOC ON)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(Qt6 6.2 COMPONENTS Gui Quick Multimedia REQUIRED)

qt_add_executable(appsuperapp
    main.cpp
)

qt_add_qml_module(appsuperapp
    URI Superapp
    VERSION 1.0
    RESOURCE_PREFIX /scythestudio.com/imports
    QML_FILES main.qml Pages/Page.qml
)

add_subdirectory(Test/MyComp)

set_target_properties(appsuperapp PROPERTIES
    MACOSX_BUNDLE_GUI_IDENTIFIER my.example.com
    MACOSX_BUNDLE_BUNDLE_VERSION ${PROJECT_VERSION}
    MACOSX_BUNDLE_SHORT_VERSION_STRING ${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}
    MACOSX_BUNDLE TRUE
    WIN32_EXECUTABLE TRUE
)

target_link_libraries(appsuperapp
    PRIVATE Qt6::Gui Qt6::Quick Qt6::Multimedia MyCompLibplugin)

install(TARGETS appsuperapp
    BUNDLE DESTINATION .
    LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR})

qt_add_library(MyCompLib STATIC)

set_target_properties(MyCompLib PROPERTIES AUTOMOC ON)
target_link_libraries(MyCompLib PRIVATE Qt6::Quick)

list(APPEND MODULE_QML_FILES
    MyButton.qml)

qt_add_qml_module(MyCompLib
    URI MyComp
    VERSION 1.0
    QML_FILES
        ${MODULE_QML_FILES}
)

The application runs fine and I'm able to use import MyComp and use MyButton. However, QtCreator shows "QML module not found" next to the import and I'm not getting code completion or highlighting on MyButton:

Is this something I can safely ignore? Is there anything I can do to help QtCreator find the module?
