Subject: [PATCH] Explicitly mark another library as static

I've also figured out why this problem wasn't obvious.
It only happens when someone's used the CMake-standard BUILD_SHARED_LIBS option, which controls the default behaviour for add_library.
When MyGUI is built as a standalone project, this won't be set (unless someone's done it manually) so it's fine.
When MyGUI is built as part of a larger project (e.g. package manager like vcpkg or CPM, or as a nested project with FetchContent), it's likely to have been set by something else.

It might be a good idea to pick the default value of MYGUI_STATIC to match BUILD_SHARED_LIBS if it's set, but I've not done that in this PR.
