[CMake] link in dashboard title to notes file

[Tom Deblauwe]

Hello,

I'm running the svn version of cdash, and I submit a notes file when 
building/testing(with bullseye) with a ctest script. I set 
CTEST_NOTES_FILES to the correct file just before the "ctest_submit()" 
call. So it gets submitted ok, and when clicking on a build name in the 
dashboard page, I see the details, with the build name and then the 
"view notes" link. However, on the cdash website, there you have a nice 
notes icon next to the build name on the main dashboard listing. How can 
I have this too?

Best regards,
Tom,
