Building static libraries with Fetchcontent

I’m trying to build a dependency statically to repackage it with another build system. Is there any way for me to set this to build statically? I can only find shared libraries in build/_deps/library-build/

If that dependency project “hardcodes” the SHARED argument in add_library(), then I reckon the only way to go about that is to patch their original CMakeLists.txt. If they don’t hardcode the library type, then perhaps they set the BUILD_SHARED_LIBS (or maybe you do?).
