Qt 5.10 version gets installed under /home and not found by cmake



  • Hi
    I have installed Qt 5.10. It ends up under /home/username/Qt/5.10.0. I believe I never chose the complete Qt to be installed under /home
    Other applications (plasma 5 probably) has installed Qt 5.6 as well but not in to the home directory.

    The problem is that cmake finds the Qt5Core_DIR at /usr/lib/x86_x64_-linux-gnu/cmake/Qt5Core and it seems that means the 5.6 version is used.
    I need to manually change this path in cmake.

    Question: How can I make sure the 5.10.0 version is found by cmake instead?
    Question2: Is it really expected that the Qt 5.10.0 version should end up under home/
    Question3: Can I move 5.10.0 or somehow force the 5.6 version to be upgrade to 5.10.0 as well?

    Hi and welcome to devnet,

    1. If you are using the command line use cmake -DCMAKE_PREFIX_PATH=/path/to/Qt/lib/cmake
    2. Yes, you can change that when you install Qt
    3. No, from what you describe Qt 5.6 comes with your Linux distribution, so don't try to replace it with a non system package.
