- Declare SystemC as system library to supress warnings in headers.
- Add a BUILD_SHARED_LIBS option
- Remove hardcoded STATIC in various add_library calls to honor the
  BUILD_SHARED_LIBS option
- Remove _deps/ directory from the build directory in GitLab pipeline
- Remove *.tdb files after test stage in pipeline
