Deprecated Qt function

[afabri]

We have a warning in this testsuite.

Lab_Demo/Plugins/PCA/Basic_generator_plugin.cpp:145:53: warning: ‘void QCheckBox::stateChanged(int)’ is deprecated: Use checkStateChanged() instead [-Wdeprecated-declarations]

But according to the Qt documentation we can replace only if we go for Qt 6.7 as minimal version, while we require only 6.4 here

[afabri]

@sloriot @lrineau do you have suggestions when is a good time to raise the minimal version?

[sloriot]

6.7 was released in april 2024. It will take some time before it will be in stable debian/ubuntu repos.

[afabri]

So we might reconsider this in May 2025.

[lrineau]

We could add the definition QT_WARN_DEPRECATED_UP_TO=0x60700 to the basic_generator_plugin target:

target_compile_definitions(basic_generator_plugin PRIVATE QT_WARN_DEPRECATED_UP_TO=0x60700)

That will disable the warning.
