Abhishekmishra2808 opened a new pull request, #3795:
URL: https://github.com/apache/nuttx-apps/pull/3795
## Summary
Makefile and CMake compiled TFLM with different flags: Make used
-DTFLITE_EMULATE_FLOAT and skipped -DTF_LITE_STATIC_MEMORY; CMake used
-DTF_LITE_STATIC_MEMORY and -O3 and skipped -DTFLITE_EMULATE_FLOAT.
## Impact
Build-system only for apps/mlearning/tflite-micro. Make and CMake now pass
the same TFLM preprocessor flags. No Kconfig or public API change. CMake TFLM
objects are no longer forced to -O3.
## Testing
```
$ ./tools/configure.sh sim:tflm
$ make -j$(nproc)
