The BSEC BME680 Arduino library currently does not compile for ESP32-S3. The linker throws an error not finding the libalgosec.a archive. This is becaue this file must reside in a separate folder "esp32s3".
I created a PR which solves this issue:

Hi cyberman54,
There was BSEC2 library version for ESP32-S3 in the topic https://community.bosch-sensortec.com/t5/MEMS-sensors-forum/BME688-BSEC2-for-ESP32-S3/m-p/61956, you could refer it.
