A Windows DLL has a single copy of its code and data for a given
process. But I guess that the problem is that Clang is statically linked
into every plugin. A proper solution for that is to build Clang as a
DLL. You can manually do that on MinGW, but not on VC++.

The `examples' directory is optionally added from the toplevel
CMakeLists.txt file. No need to add it again.
