Hi everyone, I’m new to cmake, now I can run `ctest -T Coverage` to get my code coverage, then I want to exclude `./test/*.c`, so I execute `-fprofile-exclude-files= . /test/*` and added `list(APPEND CTEST_CUSTOM_COVERAGE_EXCLUDE ".*test.*")` in `./build/CTestCustom.cmake`, but gcov still tries to find `./test/*.c` and returns error 5 .
