There are two parts to the Bosch library - the first it the BME680 driver, which, according to the license agreement can be redistributed in both source and compiled forms no problem. The other is the precompiled binary which forms the core of the BSEC library. I've integerated the BME680 library into the mynewt sensor framework. I've implemented the BSEC library as a separate mynewt module that you can optionally include into your project. This would either be commited into the main mynewt code, or available as a separate third party repository on github. The compiled library however, will not be distributed with the code and must be downloaded by the user and placed into the relevant folder in order for the project to compile.
Thanks for your comments @Kevin and @Andrey. I think for the BME680, I'll stick with USER_DEFINED for now until we can come up with a more general system. Ultimately, the gas sensor resistance is not really a final value to be used and so I think it's OK for it to fall under the USER_DEFINED category.
