   Thank you @rajeshadp for the Ermine statifier tip. That may be helpful for others.
   
   Apart from that, here's an update of the state of static builds now that we have ATS 10 released. ATS 10 has transitioned from automake to cmake. Our cmake configuration supports the use of the `-DBUILD_SHARED_LIBS=OFF` which configures the build to generate static libraries.
   
   ## How to Build Statically
   
   ```bash
   # Configure with static libraries
   cmake -B build -DBUILD_SHARED_LIBS=OFF -DCMAKE_INSTALL_PREFIX=/opt/ats
   cmake --build build
   cmake --install build
   ```
   
   ## What Gets Built
   
   With `-DBUILD_SHARED_LIBS=OFF`:
   - **Static**: All core TrafficServer libraries (tscore, inkcache, inknet, inkhostdb, etc.)
   - **Still Shared**:
     - Plugin API library (tsapi) - required for dynamic plugin loading.
     - Bundled thirdparty libraries (yaml-cpp, libswoc).
     - System libraries (OpenSSL, zlib, etc.).
   
   This hybrid approach ensures that:
   
   1. Core TrafficServer code is statically linked for easier deployment.
   2. Plugin loading capability is preserved.
   3. The resulting binary is more portable while maintaining functionality.
   
   For reference, see PR #10588.
