Cloned and built 4.11 from source on Windows.
When I build a project (non-Editor configuration), all engine plugins are being rebuilt, with a subfolder named after my project being generated in the engine plugin intermediate folders, and a binary of the form MyProjectName-PluginModuleName-Win64-Debug.lib in the binaries folder. Previously I’m fairly sure all projects using a plugin would just link against UE4-PluginModuleName-Win64-Debug.lib, which is generated once when I build the engine.
I’m getting a bunch of issues with seemingly unnecessary engine rebuilds and overly bloated project intermediate folders since moving to a source built engine, but the above seems like it might indicate what the root cause is. Anyone have an idea what’s going on here?
