Failure to build Qt6,difficult to identify the cause

Qt is now configured for building. Just run 'cmake --build . --parallel'Once everything is built, you must run 'cmake --install .'
 Qt will be installed into '/home/eric/.conan/data/qt/6.0.0-alpha/bincrafters/testing/package/77b282c64d736324b5f76544d48b516ec2ec65e6'To configure and build other Qt modules, you can use the following convenience script:
 /bin/qt-cmake-privateIf reconfiguration fails for some reason, try to remove 'CMakeCache.txt' from the build directory-- Configuring incomplete, errors occurred!
