Cannot build pyside v6.8.2 on ubuntu 24.04

[ian-uson]

every time i run the build using setup.py, it fails to build with a runtime error:

[INFO]: Copying files...
setup.py/prepare_packages: [Errno 2] No such file or directory: '/home/user/projects/pyside-setup/build/qfp-py3.12-qt6.8.2-64bit-release/install/lib/python3.12/dist-packages/shiboken6'

raise RuntimeError(msg)
RuntimeError:

setup.py invocation was: /usr/bin/python3 setup.py install --qtpaths=/home/user/Qt/6.8.2/gcc_64/bin/qtpaths6 --internal-build-type=shiboken6

if it helps, i also get this message earlier:

qt.shiboken: (shiboken) No C++ classes found!
