I had VS2022, but project was incompatible with it, so I uninstalled it and got VS2019. I assume cmake kept info of the old compilers and now fails to work

-- The CXX compiler identification is MSVC 19.29.30154.0 
-- The C compiler identification is MSVC 19.29.30154.0

What do I do?

If you change your toolchain, you should also clear your build directory and start afresh again. If you don’t want to delete your whole build directory, it should be enough to just add the --fresh option to your cmake command line, and that will discard previously computed values, including toolchain details.
