- Added new include directories for ImGui and SDL to the test CMake configuration, enhancing the testing environment.
- Updated the linkage to include ImGui and SDL targets, ensuring proper integration for GUI tests.

Benefits:
- Improved support for GUI testing by integrating necessary libraries.
- Streamlined the CMake configuration for better modularity in test setups.
