esp_mem.c in the builtin target via target_sources(builtin PRIVATE ...) called from the parent CMakeLists. This cross-directory source injection causes CMake's Ninja generator on Windows to produce unstable TARGET_PDB/RSP_FILE paths across reconfigures, changing the ninja command hash and forcing a re-archive of libmbed-builtin.a on every cmake run — even when no source changed. This broke test_rebuild_source_files. Fix by adding esp_mem.c to the IDF mbedtls component library (mbedtls_srcs) instead. The final ELF link uses --start-group, so builtin's platform.o resolves esp_mbedtls_mem_calloc/free from the component library regardless of archive order. esp_mem.c is IDF-specific code (heap_caps_calloc, sdkconfig.h) and belongs in the port layer, not in any submodule target.
