websocketpp had some ill-formed usage of template parameters which was
finally removed in C++20. Hence build fails when building with C++20
support enabled.
The patch is already in the develop branch but no new release was
done.
There are no autobuilder failures because websocketpp is a header-only
library, and there are no packages in Buildroot that depned on
websocketpp.
A build issue was encountered when bumping an internal project to
C++20. This issue triggered quite some bug reports in the project [0]
and there are backports to other package managers like vcpkg [1] and
conan [2].
