Hi,
I am trying to use the Bosch BSEC library and the e-series device for an IOT project. The BSEC library is closed source and requires a static library to be linked during the compile. Does anybody have experience with this.
I have noted several previous attempts of people trying to do this, and I have tried following the steps on their posts, with no success.

https://community.particle.io/t/bsec-sensor-library/41166
I am running Particle Workbench v1.13.8
E-series OS version 2.0.0
The errors I get are;
Executing task in folder hivesense: make -f 'C:\Users\Ben\.particle\toolchains\buildscripts\1.10.0\Makefile' compile-user -s <

I have made a build.mk file as suggested in one of the posts. Its contents is;

My Particle Workbench file structure is;
From what I can gather the libalgobsec.a is not being linked and therefore the error message undefined reference to bsec_get_version’`
Any help would be muchly appreciated.
Cheers,
Ben.
