Creating QML plugin for QSensor

sven9

Hi everyone,

I'm trying to build a QML plugin for a QSensor.
Following this blog post: https://www.qt.io/blog/qml-modules-in-qt-6.2 I managed to create a QML plugin based on QObject.

But when I add

target_link_libraries(mylib PRIVATE Qt6::Sensors)

to the CMakeLists.txt of the plugin I end up with the error message:

<path>/lib/cmake/Qt6Core/Qt6CoreMacros.cmake:617: error: get_target_property() called with non-existent target "Qt6::Sensors". <path>/lib/cmake/Qt6Core/Qt6CoreMacros.cmake:705 (_qt_internal_finalize_executable) <path>/lib/cmake/Qt6Core/Qt6CoreMacros.cmake:685:EVAL:1 (qt6_finalize_target) CMakeLists.txt:DEFERRED

When the target is an executable linking the Qt6::Sensors library works fine.

Can anybody help me solve this?

Hi and welcome to devnet,

Might be a silly question but do you have something along the lines of:

find_package(Qt6 REQUIRED COMPONENTS Sensors)

in your plugin project ?

Actually this did help. Thanks a lot.

I had

find_package(Qt6 6.2
    REQUIRED COMPONENTS Sensors
)

in the CMakeLists.txt of the plugin but after adding 'Sensors' to the 'REQUIRED COMPONENTS' in the CMakeLists.txt of the project using the plugin it works now.
