I built a project using STMCubeMX from ST, and it built. I added a few source files, added a couple of include paths, both using the GUI. It still tried to build, but the include paths were not correct, so I rearranged the order using the GUI.
Now I get: "Error: C4065E: type of input file '../Inc' unknown"
Is there manual "tuning" I can do to the uvprojx file? Do I now have to regenerate the project?
Any recourse? Bueller?
which I have rearranged the order of the include file paths,
If such rearrangement has any effect at all, you shouldn't do it anyway, because that's dabbling with the symptoms, not curing the actual problem.
That's because the only situation in which the order of include path specification can have any effect is if there are multiple include files in the path which have the same name. That's just going to keep failing in terribly interesting ways, no matter how cleverly you rearrange your include path. So don't let that happen. Make your files' names unique instead.
