Linking a hand-maintained Makefile library into ESP-IDF exposes brittle CMake ordering and cross-compilation traps. This hard-won configuration shows how `ExternalProject_Add`, `BUILD_BYPRODUCTS`, and toolchain variables can produce a reliable static archive without letting CMake overwrite local work.

A practical macOS setup checklist for ESP-IDF that flags the obsolete `easy_install` step, Homebrew’s prerequisites, and the shell environment command that makes `idf.py build` work.
