It looks like I have figured out my issue. I noticed while copying my platformIO project folder that I got Windows errors about a filepath being too long. This led me to try and move my project directory up a few levels to a folder directly under the C:\ drive. After a few iterations of simplifying the project down and moving around, I was able to eventually build my same original repository version in this new higher level directory.
So, there must be something in CMake that was not happy with the character length of the filepath of the newly added MAX8647 driver files/folders which caused it to throw this error. Would’ve been alot more helpful if it would have thrown a warning or error indicating this instead of the “Error: Couldn’t find target config target-” error, though perhaps this json file was not generated due to filepath length and thus resulted in this error.
If there are any other details I can provide for this to be helpful, please let me know. But it looks like the root issue has at least been discovered.
Thanks,
Jared
