Hi, 

websocket++ alias devel/websocketpp is incompatible with Boost
(devel/boost-libs) 1.87, and this breaks compilation of obs-studio.  It is the
nature of header-only libraries such as websocketpp that they themselves do not
apparently break as a port build, but their users do instead.

There seems to be an upstream pull request which is unmerged but has been
reviewed and tweaked here: https://github.com/zaphoyd/websocketpp/pull/1164  -
we may want to take most of its bits for our websocketpp port, but I haven't
yet tested if this would fix obs-studio.

I checked that my ports tree already includes these fixes, but apparently this
is insufficient:

    devel/websocketpp: unbreak with boost >= 1.87 and take maintainership

    Websocketpp 0.8.2 is not compatible with boost 1.87 or later without
    the patches. Although the port is header-only, patches for example and
    test .cpp files are also included, not only patches for headers. The
    test target is added as well.
