multi support missing in 1.5 for ESP32

[evansf]

BSEC2.cpp compiles in Arduino but link fails with:
Library Bosch-BSEC2-Library has been declared precompiled:
Using precompiled library in D:\Data\PROJECTS\Sketchbook\libraries\Bosch-BSEC2-Library\src\esp32
libraries\Bosch-BSEC2-Library\bsec2.cpp.o:(.literal._ZN5Bsec218updateSubscriptionEP21bsec_virtual_sensor_thf+0x0): undefined
reference to `bsec_update_subscription_m'
...etc for additional multi calls.
I have reloaded from GIT using a zip file for V1.5.0 and the library.json file shows:
"version": "1.5.2400",
My board is ESP32 Dev
So, is there no multi support for ESP32? I need to instantiate for multiple BME688 devices (up to 4) at multiple I2S addresses on a single I2S hardware connection and on multiple I2S hardware connections.
NOTE: I compiled the bme68x_demo_sample.ino using the Adafruit ESP32 Feather board spec and it also fails.

This has been tested with the BME688 development kit for multi instance and is working fine.
This could be an issue with linking the BSEC static library.
