# Special handling for plugins.
#
# For static plugins, in order to make MSBuild auto-linking magic work, where 
# the linker implicitly takes everything from the root lib/ folder, the 
# static libraries have to be moved out of lib/magnum/blah/ directly to lib/.
# Possibly would be enough to do this just for Windows, doing it also on other
# platforms for consistency.
#
# For dynamic plugins, auto-linking is not desirable as those are meant to be 
# loaded dynamically at runtime instead. In order to prevent that, on Windows 
# the *.lib files corresponding to the plugin *.dlls are removed. However, we 
# cannot remove the *.lib files entirely here, as plugins from magnum-plugins 
# are linked to them on Windows (e.g. AssimpImporter depends on 
# AnyImageImporter). Thus the Any* plugin lib files are kept, but also not 
# moved to the root lib/ folder, to prevent autolinking. A consequence of the 
# *.lib file removal is that downstream projects can't implement Magnum plugins
# that would depend on (and thus link to) these, but that's considered a very 
# rare use case and so it's fine.
#
# See https://github.com/microsoft/vcpkg/pull/1235#issuecomment-308805989 for 
# futher info.
