Qt for Python (PySide/Shiboken)

I used Qt registry to install shiboken generator as explained here https://qtinfo.dev/qtforpython/#/12 but it seems it is linked against a quite specific libicui18n version: ldd venv/lib64/python3.10/site-packages/shiboken6_generator/shiboken6 linux-vdso.so.1 (0x00007ffe78955000) libQt6Core.so.6 => /home/jeandet/Documents/prog/SciQLopPlots/venv/lib64/python3.10/site-packages/shiboken6_generator/Qt/lib/libQt6Core.so.6 (0x00007f7c0c997000) libclang.so.10 => /home/jeandet/Documents/prog/SciQLopPlots/venv/lib64/python3.10/site-packages/shiboken6_generator/libclang.so.10 (0x00007f7c09000000) libxslt.so.1 => /lib64/libxslt.so.1 (0x00007f7c0c92b000) libxml2.so.2 => /lib64/libxml2.so.2 (0x00007f7c08e76000) libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007f7c08c42000) libm.so.6 => /lib64/libm.so.6 (0x00007f7c0c84b000) libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f7c0c82b000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f7c0c826000) libc.so.6 => /lib64/libc.so.6 (0x00007f7c08a6a000) libicui18n.so.56 => not found libicuuc.so.56 => not found libicudata.so.56 => not found libdl.so.2 => /lib64/libdl.so.2 (0x00007f7c0c81f000) libglib-2.0.so.0 => /lib64/libglib-2.0.so.0 (0x00007f7c0892b000) libz.so.1 => /lib64/libz.so.1 (0x00007f7c0c805000) libgthread-2.0.so.0 => /lib64/libgthread-2.0.so.0 (0x00007f7c0c800000) librt.so.1 => /lib64/librt.so.1 (0x00007f7c0c7fb000) /lib64/ld-linux-x86-64.so.2 (0x00007f7c0d017000) liblzma.so.5 => /lib64/liblzma.so.5 (0x00007f7c0c7ce000) libpcre2-8.so.0 => /lib64/libpcre2-8.so.0 (0x00007f7c0888e000)
