VS 2022 cross-compile in WSL2 fails (CMake error?)

Question

I'm trying to compile a fairly straightforward C++ project into ELF format for containerization, and I actually had it working briefly, but now, when I try to build ANY C++ code via WSL2, it fails in the CMake stage, before it can even configure itself. I have uninstalled and reinstalled VS 2022 17.4, and even rolled back the latest Windows 11 update from yesterday, just in case, but I still get the same error implying that a cmake library isn't loading properly (although I've even installed the MS cmake in my WSL environment):

Answer 1

Finally poked the right bush, and an answer scampered out...

Apparently the 17.4 update broke the cmake/WSL integration. So I'm off to uninstall/reinstall 17.2...
