Hey guys,
It is fairly easy to rebuild the mod as-is yourself. Also:
If you "require" the library to be built against 1.7.3, you can grab my personal copy here. I recreated several builds on Azure DevOps which you can find here, and run them especially when a new KSP release is rolled out.
N.B. this is just a plain compile from the master branch, just like sarbian's Jenkins pipeline (I literally copied the command that performs the compilation).
The only thing I actually update is bumping the version during the build from 1.2.6.0 -> 1.2.6.1 to distinguish the dll's
