Add copy feature

Enhanced the Makefile to use a centralized `BUILD_DIR` variable for executable paths, increasing consistency across the build process. Adjusted the project reference generation to dynamically pair test files with their respective libraries, ensuring a more accurate and maintainable build configuration. This change streamlines the build workflow and mitigates potential errors due to path mismatches or hard-coded library links.
