However, I was looking to see if there's a way to use the C API with a statically compiled library rather than the DLL, as that would substantially simply use of the in-house software. (It would be nice to be able to just distribute the executable, and not worry about passing around library files as well; there's no installer as it's just an internal tool.)

If you're willing to get your hands dirty with CMake, you should be able to modify the add_library C API invocation from SHARED to STATIC to get the desired effect.  Attached is a patch that should get you what you want.



Hope this helps,
