           get_filename_component(QT_QTPATHS_EXECUTABLE ${QT_LRELEASE_EXECUTABLE} DIRECTORY) 
        
           set(QT_QTPATHS_EXECUTABLE ${QT_QTPATHS_EXECUTABLE}/qtpaths)

problem is:

lrelease is part of the qttools module
qtpaths is part of the qtbase module

so, on nixos, these have different prefixes

fixed by using the commented code blocks

fixed by using the commented code blocks

is there a good reason this code is commented?
maybe use the current code as fallback?

Is this the reason that it can't find my kvantum theme? All I have is "Fusion" and "Windows" when I try to configure via the GUI.

Obviously this needs to be called with pkgs.qt6.callPackage and not the other two.
It compiles perfectly fine but doesn't find the Kvantum (or any other) themes.

Is this the reason that it can't find my kvantum theme?

no. qt themes should be in $QT_PLUGIN_PATH on runtime (not on compiletime)
