Yeah, this is a known issue when building with ninja. The workaround for this is to remove src/csu/libcsu.a and then try again.

Had this issue today on WSL2 (ubuntu) and I just want to say that some other parts may cause problems like: python7, Ruby etc.
I used the same technique mentioned above for python7 but for Ruby I just disabled the submodule from CMakeLists because It just wouldn't work.

Before it gets lost, this is a bug in upstream CMake: https://gitlab.kitware.com/cmake/cmake/-/issues/24984
