    @kkoehne Great, thanks, yes "-nomake tests" solved my problem. As for tests, I will build them for the required module myself.

    @Phil7789 said in Set up additional include paths and library paths:

    include_target_directories

    it's target_include_directories(), also please try with forward slashes

    Are shlwapi.lib; user32.lib; Ws2_32.lib; automatically included in Qt or do I have to specify the full path for them too (I assume they're all system32 libs)?

    Not by Qt, but the default linker search path.

    @nicker-player
    This is not legal C++ code. The @ s are obviously intended so that something pre-processes this to change the @...@s. But nobody can tell you where/what that since you say nothing about where this is, or whether it has anything to do with Qt....

    Good Morning,

    Thank you all.

    Turned out that the problem had something to do with the OS.

    The example was developped on Linux whereas I'm working on windows.

    This is what I don't understand. It means it found the right Qt6CoreConfig.cmake file, but because of "Target Qt6::Core was not found" it does not want to set it to true

    The exact logic Qt6 and Qt6Core interacts is a bit convoluted. You can see what exactly is going on with the --trace command. My best guess is that something goes wrong in Qt6CoreDependencies.cmake.

    Anyhow, the canonical way to set up Qt6 with CMake is not Qt6_DIR, but adding /opt/Qt/6.3.0/macos to CMAKE_PREFIX_PATH - either the environment variable, or the CMake cache variable. Does that fix your issue?

    Hi,

    Did you build Qt yourself ?
    If not, how did you install it ?

    Is it possible to add some empty rows and make them unselectable? If their texts are empty, ignore selections.
