Binary distribution for Ubutu 22.04 is broken (on WSL2)

Describe the bug

ROOT installed from the binary distribtution for Ubuntu 22 is broken and can't start, at least for 6.26.08 and 6.26.10 (N.B. this is using WSL2).

Expected behavior

root should start normally.

To Reproduce

• Install dependencies via apt
  • N.B. python and python-dev do not exist on Ubuntu22; use python3 and python-is-python3 instead; likewise libglew1.5-dev should now be libglew-dev
• Download and unpack root_v6.26.10.Linux-ubuntu22-x86_64-gcc11.3.tar.gz in /opt
• cd /opt/root; source bin/thisroot.sh
• Then I get the following:

Thanks - yes, @amadio and I chatted a bit and his build without runtime_cxxmodules is much more successful. I don't know why this is causing so much trouble on WSL2.

[amadio]

Yes, I made the package after this bug was created. Not sure what causes trouble in WSL, could be just some dependency missing, but better have someone confirm this. Could also be due to changes in how pcms are searched, I'm not sure.

This is fixed in the current binary releases. Do not hesitate to re-open if this issue appears again.
