title: why is my outdir from my kcov command always empty?
body: <p>so, i need to integrate kcov in my gitlab-ci to see code coverage on a test executable executable. the documentation from kcov states that i need to run "kcov /path/to/outdir ./myexec" to generate a report in an html file. however, even if the command succedes, /path/to/outdir is still empty and i dont know why since the tests pass and kcov returns no errors</p>
  
  <p>here is the .gitlab-ci.yml:</p>
  
  <pre><code> stage: coverage
   dependencies:
    - Build
   script:
   - mkdir build/test/kcov
   - cd build/test
   - kcov --include-path=../../src /kcov ./abuse-test
   - cd kcov
   - ls
   artifacts:
    paths:
      - TP3/build
      - TP3/src
  </code></pre>
  
  <p>my test exec is abuse-test, it is generated via cmake->make and is in a folder called TP3->build->test->abuse-test</p>
  
  <p>the output of the console in the ci is the following: </p>

  <p>the kcov documentation states: "/path/to/outdir will contain lcov-style HTML output generated continuously while the application run"</p>
  
  <p>and yet, when i browse the artefacts, i find nothing</p>
