Thanks for the quick fix! With that patch, I get a successful build.
I have a few remaining warnings, which I don't claim are new in 3.11,
but they don't seem like incorrect warnings at first glance. The first
file may also have missing std::, resulting in calling the C function abs
rather than C++ std::abs, but that's still not float?
I've trimmed the build log; happy to send the whole thing if helpful.
The rest of it, aside from some harmless-looking cmake warnings, is
clean.
