We're facing the same issue in our CMake generated frameworks.... Your explanation was very helpful as indeed, with CMake we only generate one arch at a time.... I hope some workaround can be found.

At a high-level, what we would like to know is whether it is allowed to build a web extensions that can allow external connection from any website? If no, where is this documented? If yes, how can we enable this in the config? Thanks in advance!
