[cmake-developers] [CMake] Random behavior of CTEST_USE_LAUNCHERS

[Nils Gladitz]

Well what would be awesome is having the launcher extract individual 
diagnostic messages.
Then each diagnostic message could be categorized as warning, error or other
and flagged as ignored or visible.

One could even extract line (and column) information.

Then CDash could selectively:
- show only diagnostic messages which are not being ignored
- show all diagnostics (maybe with ignored diagnostics having distinct 
coloring)
- allow dynamic search to filter diagnostics

With line information one could even build external links for some web 
repository viewers.
