- Removed default install path setting from CMakeLists.txt.
- Updated test CMakeLists to include Google Test and configure test paths.
- Refactored load_test and unittest files to use defined paths for dictionaries and test data.

- Ensured all tests are properly linked and configured for execution.
Updated multiple files to replace instances of DecodeRunesInString with DecodeUTF8RunesInString, ensuring proper handling of UTF-8 encoded strings. This change enhances the robustness of string decoding across the cppjieba library, including updates in DictTrie, HMMModel, PosTagger, PreFilter, SegmentBase, and Unicode files. Additionally, corresponding unit tests have been modified to reflect these changes.
