mosquittopp.dll is linked against debug runtime

[ennorehling]

The mosquittopp.dll is linked against vcruntime140d.dll (the MS debug runtime). That makes it impossible to ship a game with it, because the Visual C++ Redistributable installers only install release libraries (vcruntime140.dll).

Since the plugin uses such a very old version of mosquitto (version 1.4.8) I haven't been able to find alternative libraries anywhere (or compile them myself).
