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.

Just run 'cmake --build . --parallel'Once everything is built, Qt is installed. You should NOT run 'cmake --install .'

After build I create new project with qmake (stackview) and run compile:
