                  scikit-build could not get a working generator for your system. Aborting build.
  
                  Building Linux wheels for Python 3.11 requires a compiler (e.g gcc).
  But scikit-build does *NOT* know how to install it on ubuntu
  
  To build compliant wheels, consider using the manylinux system described in PEP-513.
  Get it with "dockcross/manylinux-x64" docker image:
  
    https://github.com/dockcross/dockcross#readme
  
  For more details, please refer to scikit-build documentation:

i want to use opencv version > 4.5.4, and in chaquopy with python version 3.8, opencv version 4.5.1 is working,
but I see no wheels for newer version, so is it possible for me to use opencv versions > 4.5.4 in my python script

See #620, and please post a comment there explaining why you need the new opencv version.
