I do not get why my changes in hatch_cpp/toolchains/common.py appear not covered in coverage report while they are (I double checked by adding some debug print).

I also get the same locally when displaying coverage report in VS code.

Ah I see, the code is executed by subprocess.check_call in the test so pytest-cov cannot track the coverage in that case.

Ah I see, the code is executed by subprocess.check_call in the test so pytest-cov cannot track the coverage in that case.

But this can be fixed by enabling subprocess support in pytest-cov.

I pushed a new commit with that fix.
