`lcov` line mismatch when running unit test with `-DUSE_PYBIND11=ON`

## Description

`lcov` is complaining about a mismatch of lines.

While using Python 3.7 won't result in this error, Python 3.8-3.14 will display a line mismatch when generating the code coverage report, even though I have deleted the build folder.

Currently, I make it `--ignore-errors mismatch` for Python != 3.7
