[CMake] Coverage tests with gcov under Linux

[Judicaël Bedouet]

I have just tested with an other machine (a Fedora core 6). It's
better but it's a tricky thing : gcc version is 4.1 (g++ (GCC) 4.1.2
20070626 (Red Hat 4.1.2-13)). First machine is an XUbuntu.

The file main.cxx is yet marked as UNTESTED under CDash. So, I tried
with CMake 2.4-6, which is provided by Fedora, and with this version,
I can see the line which is not covered.

As soon as I can, I will download the lastest CVS version to see if
the UNTESTED problem is resolved but I can't understand why under
XUbuntu I can't have coverage results.

Thanks,

J. Bedouet
