[CMake] Getting coverage to show up

[Mathieu Malaterre]

Hi there,

  I do not understand why the coverage for the gdcm project is 0%.
Here is the ctest script I am using:

http://www.cdash.org/CDash/viewNotes.php?buildid=86800

  And it shows up as:

http://www.cdash.org/CDash/viewCoverage.php?buildid=86800

  While if I type manually:

$ make NightlyCoverage
   Site: zorglub
   Build name: Linux-g++-4.2
Start processing tests
Performing coverage
   Processing coverage (each . represents one file):
    .................................................. processed: 50 out of 431

    .................................................. processed: 350 out of 417
    .................................................. processed: 400 out of 417
    .................   Covered LOC:         15162
        Not covered LOC:     36184
        Total LOC:           51346
        Percentage Coverage: 29.53%
Built target NightlyCoverage


  Thus CDash should display 29.53%, right ?

Thanks !
