Context:
I'm dipping my toe into GitHub's lovely CI/CD facility and having a bit of difficulty.
https://github.com/rdpoor/basic-cicd is a super-simple repo designed to run unit tests and coverage tests whenever the developer branch is pushed to github.
Summary:
The unit tests pass, but Codecov fails with the error:
['error'] None of the following appear to exist as files: ./build/gcov/*.gcov
However, when I run the same makefile in my local Ubuntu environment, it does create files in ./build/gcov/.... What am I missing?
Details:
You can clone the repo and try it yourself, but here are the important bits:

Here's a transcript of what happens when I run make all ; make coverage locally:
./basic-cicd$ make all ; make coverage

As you can see, a.c.gcov and 'b.c.gcovare both present in the./build/gcov/` directory.
(Side note: admittedly my Makefile needs some work: it runs the unit tests twice, once to check for errors, a second time to generate the coverage data. If you have a fix for that, generate a pull request and I'll happily update it!)
