esp32-opencv build failed with error: 'recursive_mutex' in namespace 'std' does not name a type #14

@joachimBurket I have followed everything as stated in this wikipage here. The configuring and the generation part is fine. When I tried compiling, after making the alloc.cpp fix as stated in the documentation when I proceeded with the build I got the following errors regarding the std::mutex and thread related.

Attaching entire build log.

Please let me know how to fix this? What causes this and I have seen similar error when I tried to build opencv standalone with arm-none-eabi-gcc compiler.

Thanks, G Kowshik

Requires ESP32 with PARAM and ESP-IDF V4.4.x. This is a record of when I built a library for ESP32S3.

Thank you @nopnop2002 your excellent example saved a ton of time for me! There should be "idf.py build" before the last comment to make your guide perfect.
