before this change, these [convenience libraries](https://www.gnu.org/software/automake/manual/html_node/Libtool-Convenience-Libraries.html) were implicitly built as static libraries by default, but weren't explicitly marked as STATIC in CMake. While this worked with default settings, it could cause issues if `BUILD_SHARED_LIBS` is enabled. So before we are ready for building these components as shared libraries, let's mark all convenience libraries as STATIC for consistency and to prevent potential issues before we properly support shared library builds.
