    question:

    Note: Hunspell in Qt Virtual Keyboard is not enabled. Spelling correction will not be available.
    
    WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.
    Either set CMAKE_PREFIX_PATH or LLVM_INSTALL_DIR to the location of your llvm installation.
    On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
    On macOS, you can use Homebrew's llvm package.
    You will also need to set the FEATURE_clang CMake variable to ON to re-evaluate this check.
    WARNING: Clang-based lupdate parser will not be available. LLVM and Clang C++ libraries have not been found.
    You will need to set the FEATURE_clangcpp CMake variable to ON to re-evaluate this check.
    WARNING: QtWebEngine won't be built. node.js version 12 or later is required.

        This is user forum.
        If you want to have fast and reliable support then you need to become commercial customer - QtCompany will then provide you support directly.

          @jsulm now understood why response is slow to various questions as it dependent on user volunteering to answer.
