      - name: Build TA-Lib
        if: steps.cache-talib.outputs.cache-hit != 'true'
        run: |

Summary

  1. Cache TA-Lib: Speeds up builds by avoiding redundant downloads.
  2. Build TA-Lib: Downloads and compiles the source if not cached.
  3. Install TA-Lib: Installs the compiled library.

This setup reduces CI runtime by caching and reusing builds.
