Does the cmake config files should be placed in system path?

[Mark81]

I have a working cmake Qt 6.8.1 project, after upgrading to Qt 6.8.2, my CMakeLists.txt does not work anymore.
The first error was:

[cmake] Running /home/mark/Qt/Tools/CMake/bin/cmake -S /home/mark/resources-manager -B /home/mark/software.resources-manager/build/Desktop_Qt_6_8_2-Debug in /home/mark/software.resources-manager/build/Desktop_Qt_6_8_2-Debug.
[cmake] -- Could NOT find Qt6SerialPort (missing: Qt6SerialPort_DIR)
[cmake] CMake Error at CMakeLists.txt:14 (find_package):
[cmake]   Found package configuration file:
[cmake] 
[cmake]     /usr/lib/x86_64-linux-gnu/cmake/Qt6/Qt6Config.cmake
[cmake] 
[cmake]   but it set Qt6_FOUND to FALSE so package "Qt6" is considered to be NOT
[cmake]   FOUND.  Reason given by package:
[cmake] 
[cmake]   Failed to find required Qt component "SerialPort".
[cmake] 
[cmake]   Expected Config file at
[cmake]   "/usr/lib/x86_64-linux-gnu/cmake/Qt6SerialPort/Qt6SerialPortConfig.cmake"
[cmake]   does NOT exist

This is weird: it uses the correct cmake (inside the Qt installation) but then it looks for config files in the system directories. So I checked the project configuration and I noticed this:

Why the modules' directories are in the system path?
Is it correct?

It does not find the Qt6SerialPort module but it is installed:

This is my CMakeLists.txt file:

endif()

Here my kit configuration, it seems ok:

Do you see anything wrong in my settings?

For some reasons I had to click on "Re-configure with initial parameters" and now the variables have the correct path.
