CONFIG -= embed_manifest_dll not sufficient to prevent embedding manifests in plugins when building through Visual Studio 2008

It seems that adding CONFIG -= embed_manifest_dll in the project file is not sufficient to prevent embedding a manifest in plugins when using qmake to generate a Visual Studio 2008 solution (qmake -tp vc).

Apparently, Visual Studio 2008 needs to have an entry like GenerateManifest="false" in its VCLinkerTool section. Otherwise, by default, a manifest is generated and may prevent the plugin from loading in some environments.

When using makefiles and NMAKE on win32 platforms however, CONFIG -= embed_manifest_dll works as decribed, and the manifest is not embedded in the plugin.
