QtSerialBus implementation error

Niuzu

Hi,
I want to add SerialBus functionality to my application. (Desktop Qt 6.3.1 MinGW 64-bit) To do so I added to the CMake-file the find_package function.

CMakeLists.txt

..
find_package(Qt${QT_VERSION_MAJOR} REQUIRED SerialBus REQUIRED)
..

If I now build the project i get the folling error:

C:\Qt\6.3.1\mingw_64\lib\cmake\Qt6\Qt6Config.cmake:213: 
Warnung: 
Found package configuration file: 
C:/Qt/6.3.1/mingw_64/lib/cmake/Qt6SerialBus/Qt6SerialBusConfig.cmake but it set Qt6SerialBus_FOUND to FALSE so package "Qt6SerialBus" is considered to be NOT FOUND.  Reason given by package: Qt6SerialBus could not be found because dependency Qt6SerialPort could not be found. CMakeLists.txt:16 (find_package)

C:\Users\*name*\Desktop\MFA\MainfrankenApplication\CMakeLists.txt:16: 
Fehler: 
Found package configuration file: 
C:/Qt/6.3.1/mingw_64/lib/cmake/Qt6/Qt6Config.cmake but it set Qt6_FOUND to FALSE so package "Qt6" is considered to be NOT FOUND.  Reason given by package: Failed to find Qt component "SerialBus". Expected Config file at "C:/Qt/6.3.1/mingw_64/lib/cmake/Qt6SerialBus/Qt6SerialBusConfig.cmake" exists

What does it mean that 'Qt6SerialBus could not be found because dependency Qt6SerialPort could not be found. CMakeLists.txt:16 (find_package)' like stated in the warning?

I installed the SerliaBus module via the Qt Maintenance Tool and restarted my PC so it should have everything it needs to work. I Don't find any solution for my problem by scraping the forum or google.

Anyone has a idea how to fix this?

It means that CMake couldn't locate or load the logic for Qt6SerialPort, which is what Qt6SerialBus depends on.

How did you configure your project (command line, Qt Creator)? If you configured from the command line, how did you tell CMake about Qt?
Can you check that C:\Qt\6.3.1\mingw_64\lib\cmake\Qt6SerialPort\Qt6SerialPortConfig.cmake exists for you?
If it does, look for further warnings/errors for Qt6SerialPort in your cmake output. You can also launch cmake with --trace to make the output more verbose (but please be aware that this generates a lot of output, and potentially makes Qt Creator a bit unresponsive; better to do it from the command line and then piping the output to a file)
